New Features Introduced in Release 3.3.30
This section describes the following new features:
• G.723 codec for VoATM
• Enhanced Support for Controlling the EcanControl for Clearchannel Codec
• Codec Upspeed for Fax Modems
• Interoperability with 1AESS Switch
G.723 codec for VoATM
Release 3.3.30 supports the G.723 codec with upspeed option for VoATM circuits. G.723 codecs with a packetization period of 30 ms can reduce the bandwidth requirements for voice traffic and improve the bandwidth utilization of existing AAL2 trunks. To support fax/data modem traffic, an upspeed procedure can change from G.723 to G.711 after detection of fax/data modem tones. For more information about the upspeed option, see the "Codec Upspeed for Fax Modems" section.
A new custom profile supports the G.723 codec for VoATM. Table 2 shows the default values for custom profile 211.

Enhanced Support for Controlling the EcanControl for Clearchannel Codec
In Releases 3.3.10 and earlier, when a channel is configured to use clearchannel as the voiceband data (VBD) codec, the value of Ecan cancellation is not changed. Therefore, if the initial call was set up with echo cancellation on, it remains remain on even after upspeed to clearchannel.
Cisco recommends having Ecan cancellation off with clearchannel because the CCD vbd codec should be used for carrying transparent bit streams. With Ecan cancellation off, transparent bit streams are passed transparently through VISM without modification by echo cancellers.
In Release 3.3.20, as a fix for DDTS CSCef12950, when a channel is configured to use clearchannel as VBD codec, echo cancellation is set to off for that channel.
However, some fax adapters (Gammalink and Brooktrout) require Ecan cancellation to be on to eliminate echo on the tail circuit. To accommodate such fax adapters, Release 3.3.30 adds a parameter to the VBD codec commands to enhance control of the Ecan cancellation.
By default the EcanControl parameter is set to true for Clearchannel (Ecan Cancellation is turned off). For fax adapters that require echo cancellation, set EcanControl to false (Ecan cancellation remains unchanged).
Release 3.3.30 modifies the following commands to enhance echo cancellation control for clearchannel as the VBD codec.
• cnfvbdcodec—Configures Ecan Validation in VOIP mode
A new argument enables or disables Ecan validation for a clearchannel voiceband data (VBD) codec.
• dspvbdcodec—Displays Ecan Validation in VOIP mode
A new line displays the Ecan control state.
• cnfprofelemvbd—Configures Ecan Validation in AAL2 mode
A new argument enables or disables Ecan validation for a VBD profile.
• dspprofparams—Displays Ecan Validation in AAL2 mode
A new line displays the Ecan control state.
cnfvbdcodec
To configure voiceband data (VBD) upspeed codec on the VISM card, use the cnfvbdcodec command.
cnfvbdcodec <upspeedCodec> | <payload> <ecan_control> |
Syntax Description
upspeedCodec
|
Upspeed codec. Values are
•1 = G.711u (default for T1)
•2 = G.711a (default for E1)
•3 = G.726-32K
•4 = Clear channel
•5 = G.723.1-H (valid for template number 4 only)
•6 = G.723.1-L (valid for template number 4 only)
•7 = G.726-16K
•8 = G.726-24k
•9 = G.726-40K
|
payload
|
(Optional) Payload type. This entry provides a mechanism for the codec to upspeed. Range is 0-256. Default is 256.
|
ecan_control
|
(Optional) Enables or disables Ecan validation. Values are
•1 = Enable (default)
•2 = Disable
Note For clear channel VBD codec only
|
Command Modes
VoIP switching/VoIP trunking
Usage Guidelines
VISM uses the configured codec even if, for example, the configured codec is G.726-32k and VISM is preconfigured with G.711.
If you configure clear channel, VISM does support a mixed system clock—VISM cannot be originated at a T1 line and terminated at an E1 line, or originated at an E1 line and terminated at a T1 line.
When VISM is configured with clearchannel VBD codec, the ecan_control parameter enables or disables Ecan validation. If ecan_control is enabled (default), then while upspeeding to clearchannel VBD codec, Ecan is disabled. If ecan_control is disabled, then while upspeeding to clearchannel VBD codec, Ecan is not disabled and the behavior remains as it was in release 3.2.11.
In AAL2 modes the VISM obtains the upspeed codec from the AAL2 profile table. AAL1 modes do not support compression and therefore do not require upspeed.
The G.723.1 codecs are supported for VISM-PR cards only.
Note We recommend that you not use upspeedCodec argument values 5 or 6 with this command.
Examples
In the following example, the VBD upspeed codec is configured as clearchannel, is assigned payload type 182, and Ecan validation is disabled:
nodename.1.27.VISM8.a > cnfvbdcodec 4 128 2
nodename.1.27.VISM8.a >

Interoperability with 1AESS Switch
Release 3.3.30 extends VISM signaling capabilities to include interoperation with 1AESS switches.
1AESS Signaling Overview
The Lucent 1AESS local exchange telephone switching system was widely deployed in the 1970s across what was then the Bell System. Most 1AESS switches are replaced by the next-generation digital switches, such as the Lucent 5ESS and Nortel DMS-100. While few 1AESS switches remain, those still in service are generally heavily built-out. About 2 to 5 percent of lines are on 1AESS switches.
Service providers that offer wholesale dial, Internet/intranet, and access virtual private networks (VPNs) require remote access and expect to provide widely available service at the lowest cost. To do so, they must have Signaling System 7 (SS7) trunks to each local exchange in a service area. And for Internet service providers (ISP) or competitive local exchange carriers (CLEC) that want 100 percent dial coverage, an interface to the remaining 1AESS switches is mandatory.
Even though 1AESS switches use out-of-band SS7 signaling, they cannot disable robbed-bit signaling (RBS). Therefore, gateways that connect to the 1AESS switch must send a steady A/B bit status on specific SS7-controlled lines to prevent the 1AESS tandem from bringing trunks down and placing them in the out-of-service state. Any fluctuation in the received A/B bits might force the entire line on a 1AESS switch into the out-of-service state. To address the sensitivity of 1AESS switch to A/B bits, the connected MGX switch must send a steady stream of A/B bits towards 1AESS switch that corresponds the activity (call setup, call tear down, COT operations) on the DS0.
Configuring VISM for 1AESS Signaling
For VISM to interoperate with the 1AESS switch, you configure the VISM module to send a specific, steady A/B/C/D bit pattern to the 1AESS switch when the call is active (seize pattern) and another steady A/B/C/D bit pattern when there is no call (idle pattern). The cnflnsig command has a new signaling_type option for enabling this feature, and the dspln command displays the corresponding LineSignalingType.
Note The 1AESS feature is supported in VOIP switching mode only. Do not configure 1AESS signaling in any other mode (CSCek38088).
cnflnsig
To configure the signaling mode for a VISM/VISM-PR line, use the cnflnsig command.
cnflnsig <line_number> <signaling_type>
Syntax Description
line_number
|
Number of the line you want to bring to the out-of-service state. Range is 1-8.
|
signaling_type
|
Signaling type of the line. Values are
•1 = Channel-associated signaling (CAS)
•2 = Common channel signaling (CCS)
•3 = No signaling
•4 = 1AESS (only for T1)
|
Command Modes
VoIP switching/VoIP trunking, AAL2 trunking, AAL1 switching, switched AAL2 SVC, switched AAL2 PVC, VoIP and AAL1 SVC, and VoIP trunking/AAL2 trunking
Usage Guidelines
Confirm your entry when using this command to ensure that the signaling type is not changed while endpoints are configured for the line indicated by the line_number argument.
This command is not allowed when CIDs or CCS channels are present.
Configure the line type as either E1MF or E1MFCRC for E1 lines. Otherwise, this command is invalid.
Examples
In the following example, line 1 is configured for 1AESS:
nodename.1.27.VISM8.a > cnflnsig 1 4
nodename.1.27.VISM8.a >

New Features Introduced in Release 3.3.25
This section contains the description of the following new features:
• "SPVC Capacity Expansion" section
• "VISM-PR Alarm Events Reported in the MGX Log File" section
• "Configurable Loopback Cell Priority" section
• "History Statistics Enhancement" section
SPVC Capacity Expansion
In this release, you can now configure a maximum of 248 PVCs on a VISM-PR-8E1 card and a maximum of 192 PVCs on a VISM-PR-8T1 card. The cards must be running in the AAL2 trunking mode.
Prior to Release 3.3.25, you could configure a maximum of 64 PVCs on a VISM-PR card.
With the increase in SPVC capacity now supported, you have the option of assigning each DS0 to a separate PVC.
VISM-PR Alarm Events Reported in the MGX Log File
Prior to Release 3.3.25, VISM-PR reported the Receive Line alarms to the PXM log file.
In Release 3.3.25, in addition to the Receive Line alarms, VISM-PR reports the following alarms in the PXM log file:
•Transmitted Line alarms
•Transmitted and Received PVC alarms
•Transmitted and Received Ds0 alarms
The reporting of these alarms is applicable to all of the VISM-PR modes.
The following new commands support this feature:
• cnflnalmlog
• cnfpvcalmlog
• cnfallalmlog
• dspalmlog
By default, the alarm log is disabled on all the lines, and the timer is set to 0.

Configurable Loopback Cell Priority
The ATM OAM loopback cell is used to monitor the end to end connectivity of the PVC in an ATM network.The cell loss priority (CLP) bit in the ATM header is used to set the priority of the cell. A cell with CLP set to 0 has higher priority compared to a cell with CLP set to 1. During traffic congestion events, the lower priority cells are eligible first for discard.
The ATM OAM loopback cells in the VISM-PR card have the cell loss priority (CLP) bit set to 1 by default. These cells can be discarded during traffic congestion even though the class of service is configured to be constant bit rate (CBR). This discard can cause the SPVCs to go into alarm as a result of an OAM loopback timeout, which could result in the dropping of all calls on the SPVCs.
In Release 3.3.25, you can set the CLP bit of an OAM loopback cell to 0 on a VISM-PR card. This setting is propagated across the network to preserve the calls during traffic congestion.
CLP bit configuration is applicable to the OAM loopback cells in all configured PVCs of a VISM-PR card.
To configure the loopback cell priority, complete the following steps:
Step 1 Ensure you are logged in to a VISM-PR card and are operating in the VoIP switching/trunking or AAL2 trunking mode.
Step 2 To set the CLP bit in the OAM cell, enter the cnfoamloopbkclp command.
nodename.1.27.VISM8.a > cnfoamloopbkclp <ClpSetFlag>
Replace the <ClpSetFlag> argument with one of the following values:
•1 = Enable (default). The CLP bit of the OAM cell is set to 1.
•2 = Disable. The CLP bit of the OAM cell is set to 0.
Step 3 To display the CLP bit settings for the OAM loopback cell, enter the dspvismparam command.
The following example shows the CLP bit of the OAM cell is set to 0.

History Statistics Enhancement
In Release 3.3.25, the VISM-PR card can collect the following new statistics:
•OAM Loopback Timeout counts
•New OAM Loopback Timeout duration
•Active OAM Loopback Timeout Duration
•OAM Loopback Timeout Threshold
When all of the statistics are enabled, VISM-PR performance is not affected. All of the statistics are enabled by default except for the statistics upload file, which is enabled through CWM.
The following two commands are modified to include these new statistics:
•dsphistorystats
•dspconcnt
You can collect history statistics on PVCs 1-64. PVCs above the 64th PVC are not tracked in history statistics and cannot be displayed with the dsphistorystats command.
For more information about collecting history statistics and the commands, refer to the Cisco Voice Interworking Services (VISM) Configuration Guide & Command Reference, Release 3.3 located at the following URL on Cisco.com:
http://www.cisco.com/en/US/products/hw/switches/ps1938/products_configuration_guide_book09186a0080301d30.html

Limitations and Restrictions
The following limitations and restrictions are valid for software Release 3.3.30 for VISM/VISM-PR:
•In VISM Release 3.3.20 and later, the packetization period for G726-32K codec in custom profile 210 is 5 msec. In VISM Release 3.3.10 and earlier, this value was 10 msec. Because of this change, VISM Release 3.3.20 and later cannot interoperate with VISM Release 3.3.10 and earlier if the two releases have CIDs configured for custom profile 210 in AAL2 mode.
The packetization period change also made it difficult to upgrade from VISM Release 3.3.10 and earlier to VISM Releases 3.3.20 through 3.3.30, when CIDs were configured for G726-32K codec in custom profile 210 in AAL2 mode. The workaround was to clear the card configuration, upgrade the software, and then reconfigure the card.
VISM Release 3.3.30 resolves the upgrade problem (CSCek34084). You can now upgrade from all VISM releases to Release 3.3.30 normally, even when CIDs are configured with custom profile 210 in AAL2 mode. However for VISM Release 3.3.10 and earlier, you must increase the bandwidth of PVCs for CIDs that use custom profile 210 prior to the upgrade. This is because the upgrade automatically decreases the packetization period to 5 msec for CIDs using custom profile 210, but does not automatically increase the PVC bandwidth for those CIDS.
•If you are upgrading the VISM-PR image to Release 3.2.1x or later and the PXM1E or PXM45 image from Release 4.x or earlier to Release 5.x, first upgrade the VISM-PR cards. Then, upgrade the PXM1E or PXM45 cards in the same node.
Do not configure the new VISM features until you have fully upgraded the network. After you upgrade your network to PXM1E or PXM45 Release 5.x or later and VISM-PR to Release 3.2.1x or later, apply the standard upgrade process.
•Cisco recommends that you use the cnfcodecjtrdelay command to configure the fixed jitter-delay argument to 20 ms when using VISM-PR 3.3.30.
•In a PNNI network, upspeeding SVC fax or modem calls requires an increase in bandwidth between the voice codec and the vbd codec. For fax calls to go through, you must disable policing.
•Switched AAL2 PVC mode is not recommended as this mode requires a meshed PVC network topology, which does not scale.
•The following commands are not supported:
–cnfmaxconfnum
–dspconferences
–dspmaxconfnum
•GR-303 is not supported for the LAPD commands.
•In AAL2 SVC mode, all active calls on the VISM cards are dropped upon PXM hard and soft switchover.
•For VISM-PR cards that are running on a PXM45 chassis, you can add connections to a maximum of 11 VISM-PR cards.
To add more cards and connections, you must enable the expanded memory option on the PXM45 card by using the cnfndparms (option 4) command.
•When configuring VoIP for modem or fax upspeed (passthrough), set the EventNegoPolicy parameter of the cnfvoiptransparams command to the value all.
This configuration is required for all related upspeed codecs to function correctly. An upspeed codec is defined as the codec that is switched to G.711a/u law, Clear Channel, or G.726.
•For a list of open issues and mitigations in VISM Release 3.3.27, see "Caveats in Release 3.3.30" section.
Upgrade Procedures
This section describes the following upgrade procedures:
• Prerequisites
• VISM/VISM-PR Upgrades with PXM1
• Upgrading VISM-PR with PXM1E and PXM45
• Downgrading VISM/VISM-PR
• Upgrading VISM to VISM-PR Hardware
VISM/VISM-PR Release 3.3.30 provides a procedure for the graceful upgrade (one in which the existing VISM/VISM-PR configuration is preserved throughout the upgrade procedure) from one of the following releases:
•From VISM 3.2.11 to VISM 3.3.30
•From VISM 3.3 to VISM 3.3.30
•From VISM 3.3.20 to VISM 3.3.30
•From VISM 3.3.25 to VISM 3.3.30
Prerequisites
To ensure that the VISM/VISM-PR configuration is preserved throughout the upgrade procedure, you must complete the prerequisites listed in this section.
Before starting the graceful upgrade procedure, complete the following prerequisites:
•Configure your MGX 8000 Series shelf with at least two VISM cards in a redundant configuration.
For more information on adding redundancy, refer to the add redundancy, addred, command in the Cisco MGX 8250, Cisco MGX 8230, and Cisco MGX 8850 PXM1-based Command Reference documentation and the Cisco MGX 8830 and Cisco MGX 8850 PXM1E/ PXM45-based Command Reference documentation.
•Ensure that the VISM cards are running at least Release 2.1, and the VISM-PR cards are running at least Release 3.0.
•Download software Release 3.3.30 for VISM/VISM-PR to the MGX 8000 Series shelf.
•If you are using the CALEA feature, ensure that you have the version of VISM/VISM-PR software that supports CALEA.
VISM/VISM-PR Upgrades with PXM1
This section describes the procedures for upgrading VISM/VISM-PR software when the VISM/VISM-PR is used with a PXM1 card.
Downloading VISM/VISM-PR Boot Code and Firmware to PXM1
To download the VISM/VISM-PR boot code and firmware to the PXM1 card, use TFTP.
Step 1 Log in to your TFTP server.
Step 2 Download the bootcode and firmware images from the Cisco website.
Step 3 Download the selected revision of service module boot code into the service module.
a. tftp <node_name or IP address>
b. bin
c. put <backup boot> POPEYE@SM_1_0.BT
d. quit
Step 4 Download the selected firmware file.
a. tftp <node_name or IP address>
b. bin
c. To upgrade all VISM cards:
put <FW file> POPEYE@SM_1_0.FW
quit
d. To upgrade an individual VISM card:
put <FW file> POPEYE@SM_1_<slot number of card to upgrade>.FW
quit
Note Do not enter two put commands in the same TFTP session.
Step 5 Proceed to the "Upgrading VISM/VISM-PR Firmware with PXM1 Card" section to install the download.
Upgrading Boot Code with PXM1 Cards
Complete the following steps to upgrade the new backup boot code when you are using PXM1 cards in in a Cisco MGX 8230, Cisco MGX 8250, and Cisco MGX 8850 chassis:
Step 1 Log in to the active PXM1 card (slot 7 or 8 for Cisco MGX 8250 and Cisco MGX 8850 chassis; slot 1 or 2 for Cisco MGX 8230 and Cisco MGX 8830 chassis).
Note VISM/VISM-PR must be in the active state to update the VISM/VISM-PR boot code.
Step 2 Execute the PXM1 install command.
nodename.1.27.VISM8.a > install [bt] [sm <slot>] <version>
Caution Do not touch the VISM/VISM-PR card until the status comes back ('Sent xxx bytes in yyy seconds'). Failure to follow this recommendation corrupts the boot code, which cannot be recovered.
When the boot code is being written to PROM, you see comments displayed at the VISM/VISM-PR prompt. This behavior is normal and expected.
Step 3 Type the version command to verify the correct boot code.
Note Step 3 is optional.
Upgrading VISM/VISM-PR Firmware with PXM1 Card
Software Release 3.3.30 is for VISM and VISM-PR cards. Ensure that the VISM and VISM-PR cards have the minimum boot code version of vism_8t1e1_VI8_BT_3.2.00.fw.
The following versions of VISM software Release 3.3.30 are available:
•003.003.030.200.FW—without CALEA
•003.053.030.200.FW—with CALEA
In this procedure the following conditions apply:
•If two VISM or VISM-PR cards are part of a redundancy group, initially the primary card is in the active state, and the secondary card is in the standby state.
•Old-rev refers to the firmware, Release 3.2 and prior.
•New-rev refers to the firmware after the upgrade, Release 3.3.30.
Perform the firmware upgrade on the VISM or VISM-PR cards. Do not remove the VISM cards and replace them with VISM-PR cards at this time.
Step 1 Log in to the active PXM1 card (slot 7 or 8 for Cisco MGX 8250 and Cisco MGX 8850 chassis; slot 1 or 2 for Cisco MGX 8230 and Cisco MGX 8830 chassis).
Step 2 Save the existing configuration as a contingency plan by entering:
nodename.1.8.PXM.a > savesmcnf <SM slot#>
This command saves the existing configuration in the C:CNF directory. This file can be used during the downgrade procedure.
Step 3 To obtain the correct version of VISM/VISM-PR firmware, enter the dspfwrevs command.
nodename.1.8.PXM.a > dspfwrevs

VISM-8T1E1 05/10/2005 19:59:52 4037880 003.003.020.000 sm150.fw
Step 4 Execute the PXM install command.
nodename.1.8.PXM.a > install sm <SM slot#> <new-rev>
Replace <SM slot#> with the slot number of the primary VISM or VISM-PR card.
Replace <new-rev > with the version of the new firmware (for example, 003.003.030.200.FW).
The install sm command causes the secondary VISM or VISM-PR card to reset and come up in the standby state, running the new-rev firmware. The primary VISM or VISM-PR card is unaffected by this command.
Caution Ensure that you perform
Step 4. If you do not perform
Step 4, the boot code is corrupted and not recoverable.
Step 5 Execute the PXM newrev command.
nodename.1.8.PXM.a > newrev sm <SM slot#> <new-rev>
Replace <SM slot#> with the slot number of the primary VISM or VISM-PR card.
Replace <new-rev> with the version of the new firmware.
The newrev command causes the primary VISM or VISM-PR card to reset. The secondary VISM or VISM-PR card becomes active and runs the new-rev firmware.
Step 6 Execute the PXM commit command.
nodename.1.8.PXM.a > commit sm <SM slot#> <new-rev>
Replace <SM slot#> with the slot number of the primary VISM or VISM-PR card.
Replace <new-rev> with the version of the new firmware.
The two VISM or VISM-PR cards are now back to their original condition, except that both cards are now running the new-rev firmware.
Step 7 Log in to the active VISM or VISM-PR card and use the display commands (for example, dspendpts, dspcasvar, and so forth) to confirm that the configuration has been preserved through the upgrade process.
Note For more than one primary VISM or VISM-PR card in a redundancy group, ensure that the secondary card is in the standby state, and repeat Step 5 and Step 6 for each VISM/VISM-PR card in the redundancy group.
Step 8 Perform the following verifications:
•Make minor modifications to the configuration.
•Check that the changes have been executed correctly.
•Change the configuration back again.
Note If the VISM or VISM-PR card is not part of a redundancy group, complete only
Step 1 to Step 4.
Upgrading VISM-PR with PXM1E and PXM45
This section describes the procedures for upgrading VISM-PR software when the VISM-PR is used with a PXM1E or PXM45 card.
To upgrade the VISM-PR image to Release 3.2.1x or later and the PXM1E or PXM45 image from Release 4.x or earlier to Release 5.x, first upgrade the VISM-PR cards. Then, upgrade the PXM1E or PXM45 cards in the same node.
Do not configure the new VISM features until you have fully upgraded the network. After you upgrade your network to PXM1E or PXM45 Release 5.x or later and VISM-PR to Release 3.2.1x or later, apply the standard upgrade process.
Downloading VISM-PR Boot Code and Firmware to PXM1E and PXM45
To download the VISM-PR boot code and firmware to the PXM1E or PXM45 card, use FTP.
Step 1 Access the boot code and firmware images on Cisco.com.
Step 2 To download the images, enter the ftp command.
ftp node-ip
The node-ip argument is the IP address of the node to which you want to download the image.
Step 3 Enter your user name and password.
Step 4 Enter bin.
Step 5 Change to the C:FW directory.
cd C:FW
Step 6 Download the images to your C:FW directory.
a. To download one file at a time, use the put image-version command.
b. To download multiple files at the same time, use the mput <image-version> <image-version> command.
The image-version argument is the image that you accessed in Step 1.
Step 7 To exit the download procedure, enter bye.
Upgrading Boot Code with PXM1E and PXM45 Cards
Complete the following steps to upgrade the new backup boot code when you are using PXM1E or PXM45 cards in your MGX 8000 Series chassis:
Step 1 Complete the steps in the "Downloading VISM-PR Boot Code and Firmware to PXM1E and PXM45" section.
Step 2 Log in to the active PXM1E or PXM45 card.
Step 3 To upgrade the VISM-PR boot, enter the burnboot command.
nodename.1.7.PXM.a > burnboot <slot> <revision>
Replace <slot> with the number of the VISM-PR card that you want to upgrade.
Replace <revision> with the version of the bootcode you downloaded from Step 1.
The following example shows sample results from the burnboot command.
nodename.1.7.PXM.a > burnboot 12 3.2(0.0)
The card in slot 12 will be reset.
burnboot:Do you want to proceed (Yes/No)? yes
For VISM-PR cards without redundancy, the card automatically resets and becomes active with the latest boot code image.
For VISM-PR cards with redundancy, the active card takes approximately 60 seconds to reset as standby. For the original standby card, complete Step 2- Step 3. This card now resets and becomes the standby again, and the standby card is now active.
Upgrading VISM-PR Firmware with PXM1E and PXM45 Cards
Complete the steps in this section to upgrade the VISM-PR firmware. Ensure that the VISM-PR cards have the minimum boot code version of vism_8t1e1_VI8_BT_3.2.00.fw.
The following versions of VISM-PR software Release 3.3.30 are available:
•003.003.030.200.FW—Without CALEA
•003.053.030.200.FW—With CALEA
Caution If you plan to upgrade PXM cards and VISM-PR modules, upgrade the PXM cards first. Wait until the PXM cards are operating in active and standby modes with the correct software before upgrading the VISM-PR modules. Failing to upgrade the node in the correct order can fail VISM connections, causing significant service disruption.
Perform the firmware upgrade on the VISM-PR cards.
Step 1 Log in to the active PXM1E or PXM45 card.
Step 2 Ensure that the card is in the redundant mode, where the active card is the primary card.
Step 3 To save the existing configuration, enter the saveallcnf command.
nodename.1.7.PXM.a > saveallcnf
Step 4 To load the new software, enter the loadrev command.
nodename.1.7.PXM.a > loadrev <sm-primary-slot-num> <new-rev>
Replace <sm-primary-slot-num> with the slot number of the VISM-PR card on which you want to install the new software.
Replace <new-rev> with the new firmware version number for the VISM-PR software.
Caution Temporary traffic loss occurs.
Step 5 Ensure that the redundant card is returned to the standby state by executing the dspcds command.
Note You must wait for the redundant card to return to the standby state. If you issue the runrev command too early, an error message is generated. The rev change does not occur.
Step 6 To execute the download, enter the runrev command.
nodename.1.7.PXM.a > runrev <sm-primary-slot-num> <new-rev>
Replace <sm-primary-slot-num> with the slot number of the VISM-PR card on which you want to install the new software.
Replace <new-rev> with the new firmware version number for the VISM-PR software.
Caution Temporary traffic loss occurs.
Step 7 Ensure that the primary card completes booting up and goes into the standby state by executing the dspcds command.
Note You must wait for the primary card to finish booting up and get to standby state. Issuing the commitrev command early might be accepted without an error. However, the active and standby cards might not be swapped back to their original states. For example, the original primary card might be left in standby, and the original redundant card might be left as active.
Step 8 To commit the new download to the VISM-PR card, enter the commitrev command.
nodename.1.7.PXM.a > commitrev <sm-primary-slot-num> <new-rev>
Replace <sm-primary-slot-num> with the slot number of the VISM-PR card on which you want to install the new software.
Replace <new-rev> with the new firmware version number for the VISM-PR software.
The commitrev command switches the primary card from a standby state to an active state and the redundant card from an active state back to a standby state.
Step 9 To verify the card states, execute the dspcds command.
Downgrading VISM/VISM-PR
Use this procedure to downgrade VISM/VISM-PR software from software Release 3.3.30 to an earlier VISM/VISM-PR release. If you use the downgrade procedure described here, you can retain the configurations after the downgrade.
Note The configurations that existed with old-rev firmware should have been saved earlier. You cannot downgrade from VISM-PR to VISM.
Complete the following steps to downgrade the VISM/VISM-PR software:
Step 1 If the VISM/VISM-PR card is in a redundancy group, remove the redundancy.
nodename.1.7.PXM.a > delred <SM slot#>
Step 2 Download the old-rev firmware onto the MGX shelf.
Step 3 Execute the PXM clrsmcnf command.
nodename.1.7.PXM.a > clrsmcnf <SM slot#>
Replace <SM slot#> with the slot number of the VISM/VISM-PR card to be downgraded.
Wait for the card to become active. The VISM/VISM-PR card resets after you execute this command.
Step 4 Execute the PXM restoresmcnf command.
nodename.1.7.PXM.a > restoresmcnf -f <filename> -s <SM slot#>
Replace <filename> with the name of the old configuration file that was saved while the old-rev firmware was running. The file can be found in the C:CNF directory on the MGX shelf.
Replace <SM slot#> with the slot number of the VISM/VISM-PR card to be downgraded.
The VISM/VISM-PR card resets again. The card becomes active, running the old-rev firmware with the old configuration.
Note For PXM1E/PXM45 cards, you cannot restore the configuration for an individual VISM-PR service module. You can save and restore the configuration of all cards in a chassis using the saveallcnf and restoreallcnf commands.
Caution The
restoreallcnf command reconfigures all of the cards in the chassis.
Step 5 Reconfigure the redundancy group, if required.
Upgrading VISM to VISM-PR Hardware
Complete the following steps to upgrade your system from VISM cards to VISM-PR cards.
Caution For this procedure, you must install the redundant (standby) VISM-PR card first. Failure to follow this recommendation results in traffic loss. In addition, do not remove an active VISM card from your chassis. Ensure that you change an active VISM card to the standby state before you remove it and replace it with a VISM-PR card.
Step 1 Remove the redundant (standby) VISM card from its slot in your chassis.
Step 2 Install a VISM-PR card in the same slot.
Step 3 Administratively configure the VISM-PR card you installed in Step 2 as primary (active).
Step 4 Remove the now redundant VISM card from your chassis.
Step 5 Install a VISM-PR card in the slot from which you removed the VISM card in Step 4.
Step 6 Log in to the redundant (secondary) VISM-PR card and execute the dspcd command. Verify that the output from the dspcd command lists the card type under FunctionModuleType as a VISM-PR card. If the card type still indicates the VISM card, execute the resetcd slot-num command from the PXM and repeat the dspcd command to ensure that the correct card type is shown.
Step 7 Log in to the active VISM-PR card and execute the dspcd command. Verify that the output from the dspcd command lists the card type under FunctionModuleType as a VISM-PR card.
If the card type still indicates the VISM card, execute the resetcd slot-num command from the PXM. Repeat the dspcd command to ensure that the correct card type is shown.
Step 8 If you have no other VISM cards in your chassis, you have completed the hardware upgrade procedure; do not proceed to Step 9. If you have more VISM cards in your chassis, proceed to Step 9.
Step 9 Remove a standby VISM card from its slot in your chassis.
Step 10 Install a VISM-PR card in the same slot.
Step 11 Repeat Step 9 and Step 10 to remove any remaining VISM cards in your chassis and replace them with VISM-PR cards.
Step 12 Repeat Step 6 and Step 7 on the remaining VISM-PR cards to ensure that the correct card type is shown for each.

Description

CSCei51973
|
Headline: Fax retrains to a lower data rate in case of VISM <-> IOS interop
Symptom: With a T38 Fax Relay call between VISM-T1/VISM-PR-T1 (Template 3;G711u) and 5300, 2421 and 3745 IOS platforms, the fax transmission retrains from 14400bps to 12000bps. The fax transmission is successful but only at the lower data rate.
Conditions: With a T38 Fax Relay call between VISM-T1/VISM-PR-T1 (Template 3; G711u) and 5300, 2421 and 3745 IOS platforms, the fax transmission retrains from 14400bps to 12000bps. The fax transmission is successful but only at the lower data rate. This occurs only when the IOS (5300, 2421 & 3745) platforms originate fax calls. The fax calls operate correctly when VISM/VISM-PR originates the call. Also, for VISM interop with 5400 and 3810 this problem is not observed.
Workaround: Because the fax call does not fail, only the speed at which the fax is transmitted is affected, so this is not a major issue.

|
Headline: Card resetting after fax calls are run in VOIP trunking mode.
Symptom: Card resets after fax calls are run across VISM PR E1 cards.
Conditions: Single PVC for bearer and control traffic.
Workaround: None.
|
CSCek49386
|
Headline: Voice calls in VOIP Trunking E1 CAS failing with g729ab codec
Symptom: In VISM PR E1 cards, VOIP trunking calls are run with CAS signalling. The voice calls are not going through on all endpts, pass % is around 90%.
Conditions: VOIP trunking mode, CAS signaling, rtpcons with G.729 ab and pp 10ms, vbdcodec PCMA, VAD disabled, and ECAN on.
Workaround: With all other codecs, the voice calls have 100% success rate.
|
CSCek50971
|
Headline: CAP MIB Update for not supporting vismRtpTriRedundancy, lossless Codec
Symptom: vismRtpTriRedundancy and lossless type in vismRtpCodecType are not supported in the VISM.
Conditions: VISM with the latest 3.3 image.
Workaround: None
|
CSCek51873
|
Headline: VISM resets when UDP attack, when access vismparam
Symptom: VISM resets while accessing the cli dspvismparam, when udp attack is occurring.
Conditions: Releases 3.3.10, 3.3.25, 3.3.30.
Workaround: dspvismparam should not be used while the udp attack is going on. However, after udp attack is stopped, dspvismparam is successful.
|
CSCin96578
|
Headline: DTMF digit detection failure w G723 codecs in VoIPTR mode

Description
|
CSCei29995
|
Symptom: VISM-PR reports latency of zero when it interoperates with platforms: 2421, 3745, and 5400.
Conditions: This issue is seen intermittently in VISM-PR interop testing with 2421, 3745, and 5400.
Workaround: None.
|
CSCei51973
|
Symptom: Fax retrains to a lower data rate in case of VISM <-> IOS interop.
Conditions: With a T38 Fax Relay call between VISM-T1/VISM-PR-T1 (Template 3; G711u) and 5300, 2421, and 3745 IOS platforms, the fax transmission retrains from 14400 bps to 12000 bps. The fax transmission is successful but only at the lower data rate.
This conditions occurs when the IOS (5300, 2421, and 3745) platforms originate fax calls. The fax calls run successfully when VISM/VISM-PR originates the call.
With VISM interoperating with 5400 and 3810 platforms, this problem is not observed.
Workaround: None.
|
CSCej06477
|
Symptom: When 248 PVCs are configured and CIDs with G711a and VAD off are added per PVC, some PVCs go into failed state.
Conditions: The problem occurs if all 248 PVCs are added and each PVC has one CID on it.
Workaround: None.
|
CSCej12076
|
Symptom: VISM stops transporting DTMF after BW change.
Conditions: CIDS are in alarm state and are not able to transmit DTMF digits.
Workaround: None.
|
CSCej45540
|
Symptom: The UDP port used by the static RTP stream is used later by a dynamic RTP stream, which causes the datamover to send all of the data from the C7 signaling stream to the incorrect DSP channel.
Conditions: This issue occurs because after 1 to 2 hours, more than 248 dynamic RTP connections are set up. The 249 dynamic RTP connections use UDP port 49684, which is used by slot 2, C7 signaling channel. If the call rate is less, the time it takes to the dynamic RTP connection is more.
Workaround: Delete the RTP connections for the C7 signal, and add them back with a local UDP port greater than 49748.
|
CSCej61968
|
Symptom: Even after successfully recovering from DSP failure, VISM sends a 900 DSP Failure message in response to AUEP message CA.
Conditions: This issue occurs with a DSP failure.
Workaround: None.

DDTS Issue
|
Description
|
CSCeh72843
|
Symptom: CLI dspconcnt shows false AAL5 statistics when AAL2 CIDs have been deleted and re-added.
Conditions: This symptom occurs with the following conditions:
•AAL2 trunking
•CIDs added, deleted and re-added
•Releases 3.3.10 and earlier
Workaround: Do not delete and re-add CIDs.
Issue the clrsmcnf command and reconfigure the card if CIDs are changed and statistics are needed.
|
CSCei25172
|
Symptom: VISM lines are stuck in AIS.
Conditions: VISM-PR-8T1 is configured for AAL2 trunking and has CID. When the DS3 links go down and come back up, the VISM line remains stuck in AIS alarm.
Workaround: Disconnect and then reconnect the VISM cable.
|
CSCei30249
|
Symptom: VISM resets itself upon receiving RTP packets with different SSRCs on each RTP packet.
Conditions: The symptom happens only when VISM receives RTP packets with different SSRCs on each RTP packet.
This condition occurred with 12.3.4T6 on one of its IAD 2431 to create the problem.
Workaround: Fix the issue on the other side of the RTP session so that the correct SSRCs are used.
|
CSCei54326
|
Symptom: VISM stops sending RTCP packets after cnfgwoos forceful.
Conditions: RTCP packets are not sent from VISM for any of the calls when the VISM meets the following conditions:
1. One hundred or more active calls exist.
2. The gateway is forcefully taken out of service: cnfgwoos 2
3. The gateway is put back in service: cnfgwis
Workaround: Take the gateway gracefully out of service: cnfgwoos 3
|
CSCei54618
|
Symptom: Discrepancy in the VISM statistical information.
Conditions: The issue was observed with the CTM /MGM 5.0 Element Management on the MGX 8850 with VISM-PR-8T1/E1 Release 3.3.10.
Workaround: Use SNMP to get the current real-time and last 15 minute statistics for unavailable seconds (UAS) statistics.
Further Problem Description: The incorrect report value is of the UAS that is calculated by the VISM-PR.
|
CSCei61996
|
Symptom: VQT Stats: Latency is different between each direction of a call. During the early stage of a call, the A-->B and B-->A directions of a call report different values of latency.
Conditions: This symptom occurs with the following conditions:
•VAD ON
•Fixed jitter buffer
•Timestamp disabled
•VoIP switching mode
Workaround: Use one of the following workarounds:
1. Fixed jitter buffer mode with timestamp enabled
2. Adaptive jitter buffer mode
3. VAD disabled
|
CSCei85965
|
Symptom: CIDs are put in OOS as a result of insufficient bandwidth.
Conditions: Subsequent CIDs will be put in OOS after a card reset.
Workaround: Increase the bandwidth on the PVC.

Description
|
CSCef12950
|
Symptom: VISM does not disable the ECAN when the codec used is Clear Channel.
Conditions: This symptom occurs when Clear Channel is set as the upspeed codec for fax/modem calls. In addition, this occurs when Clear Channel is used as a voice codec and if ECAN is enabled during call setup.
Workaround: Do not enable the ECAN through the MGCP, if the codec to be used is Clear Channel. VISM does not reject the MGCP command if ECAN is turned on and the preferred codec is Clear Channel.
|
CSCeg25307

Symptom: Increasing the jitter buffer has no effect in one-way delay.
Conditions: No significant change on one way delay was observed with fixed jitter buffer settings between 60 ms and 100 ms. The expected behavior is that increasing the jitter buffer would also increase the one-way delay value. Tests were performed in AAL2 Trunking mode.
Workaround: None.
|
CSCeg61617
|
Symptom: VISM crashes hours after running PRI backhaul load.
Conditions: While running PRI backhaul load on a fully loaded VISM-PR, the card would reset after running between 12-80 hours.
Workaround: The problem is fixed in VISM Patch Release 3.3.0.202. If you are running PRI backhaul load on VISM-PR, it is recommended that you upgrade to this patch release.
Contact Cisco TAC to obtain VISM Patch Release 3.3.0.202.
|
CSCeg82063
|
Symptom: VISM is not passing packets even if received at the ATM level as shown with the dspsarcnt command.
On the contrary dsprtpconnstat does not show any RTP packets received or rejected.
Conditions:
1. VISM should run 3.2(11.202) or above.
2. The CPE should use a different UDP port as source form the UDP, one used as destination. Code 3.2(11.202) introduced this check for security reasons.
Workaround: Revert back to 3.1.
|
CSCeg85887
|
Symptom: Card resets when running T.38 load in template 4.
Conditions: When configured to template 4, VISM DSPs crash if running T.38 GW mode load.
Workaround: Configure the VISM card to template 3, which supports T.38 fax relay.
|
CSCeg86053
|
Symptom: In 3.3.10 release, when using ATM Fax Relay feature, VISM checks for at least 200 cps to be available before it can upspeed the CID to Fax Relay mode.
However, it utilizes only 50 cps once in Fax Relay mode.
Conditions: This affects fax calls on VISM when using a template in AAL2 trunking mode. The configured bandwidth is lesser than that used by fax passthrough.
Workaround: Configure the PVC with extra bandwidth of 140 cps, which allows the fax calls on VISM to upspeed to Fax Relay mode.
|
CSCeg86125
|
Symptom: When VISM is working with Arris MTAs through DTMF relay and the DTMF digits duration is no more than 50 ms, Arris MTA fails to outpulse the digits correctly. MTAs from other vendors work fine.
Conditions: This only happens to Arris MTAs when the DTMF digits are less than or equal to 50 ms. For digits longer than 50 ms, it works fine.
Workaround: None.
|
CSCeh35201
|
Symptom: VISM crash with E1 CCS load. ATMizier not responding.
Conditions: This reset happens in AAL2 Trunking mode with CCS channels that are configured with signaling PVCs.
Workaround: Do not configure CCS channels with signaling PVCs. Use Clear Channel codec with bearer PVCs to transport signaling.
|
CSCeh36322
|
Symptom: Six extra packets cause metallic voice.
When 6 out-of-order RTP packets are received, PSTN side hears robotized voice with the following configuration:
•dejitter buffer mode: fixed without timestamp
•initial delay: 20 ms
•codec: G.711A
•packetization period: 20 ms
Conditions: This problem happens in fixed without timestamp dejitter mode and the above specific configuration.
This issue does not happen when less than or more than 6 packets are received.
This issue is cleared by another extra packet being added or one packet being dropped.
Workaround: Use fixed with timestamp dejitter buffer mode.
|
CSCeh47379
|
Symptom: CCS AAL2 Trunking load of 200 V.110 calls cause reset.
VISM-E1/VISM-PR-E1 cards might intermittently reset. For a non-redundant configuration, the card resets and comes back active. If redundancy is configured, the card fails over to a redundant card. PXM log shows reset reason as Watchdog Timeout.
Conditions: VISM-E1/VISM-PR-E1 might intermittently reset if all of the following conditions are met:
1. Card is configured for AAL2 Trunking mode.
2. Statistics upload feature for VISM-E1/VISM-PR-E1 is enabled, including CID statistics. By default, statistics upload feature is disabled.
3. VISM-E1/VISM-PR-E1 has 200 or more CIDS configured.
Workaround: One of the following workarounds can be applied, depending on the customer's requirements related to statistics upload to minimize an impact to their statistics upload capability.
1. Disable statistics upload feature all together for all narrow band service module (NBSM) cards.
2. Enable statistics upload feature only for other NBSMs only.
3. Enable statistics upload feature for VISM-E1/VISM-PR-E1, but only for PVC and/or line statistics (no CID statistics enabled).

Open Caveats
Table 22 describes the open caveats in VISM/VISM-PR Release 3.3 as of September 27, 2004.
Table 22 Open Caveats for VISM/VISM-PR Release 3.3
DDTS Issue
|
Description
|
CSCec54765
|
Symptom: VISM regenerates incorrect DTMF on-times in VoIP Trunking mode.
Conditions: When DTMF digits with on-times of less than 50 ms are detected on the near-end VISM, the digits are regenerated with inconsistent on/off times on the far end VISM.
Workaround: Ensure the DTMF digits that are detected have an on-time value greater than 50-60 ms (preferably greater than 60 ms).
|
CSCed59217
|
Symptom: VISM-PR keeps sending DTMF digits when no digit is pressed.
Conditions: By random press of the digits on both on-net and off-net phone or the combination of various digits at the same time, the VISM-PR card sends out the DTMF payload type 101 packets every 50 ms (like retransmission) even when digit is entered from the TDM side.
Workaround: Press another digit in the normal fashion to clear the problem.
|
CSCed83268
|
Symptom: Lower than expected throughput on V.90 modem calls over AAL2. Some modem calls speed shift to V.34 speeds and/or retrain.
Conditions: This symptom occurs with VISM to VISM calls as well as VISM to VXSM calls.
Workaround: None.
|
CSCee92429
|
Symptom: Voice quality issue due to AAL2 packet drops.
Conditions: Configure 248 CIDS with G.711a 5 ms with VAD off and subcell muxing enabled from one VISM-PR-E1 to another VISM-PR-E1.
Delete some CIDS on one VISM-PR and re-add. The following errors are seen on other side thus causing voice quality issue:
•AAL2 HEC errors
•AAL2 invalid OSF cells
•AAL2 invalid length
Workaround:
1. Turn subcell muxing off and/or turn VAD on.
2. Use G.729 or other 10 ms/20 ms codecs.
|
CSCef02022
|
Symptom: VISM advertising the NTE capability with DTMF relay disabled.
Conditions: When DTMF Relay is disabled on the VISM, the NTE capability is still advertised by the VISM.
Specifically, when the VISM is configured for DTMF relay off (cnfvoiptransparams 2 1 1 1), VISM response to the call agent still advertises the VISM bearer capability to use NTE for digits 0-15.
Workaround: None.
|
CSCef32606
|
Symptom: DSPs stop responding to ping after re-download is initiated when DSPs failed.
Conditions: This condition is random. Some DSPs might or might not re-download. This symptom happens when you have connections that are associated with the DSPs prior to the failure. DSP status is not in active state.
Workaround: Reset the card.
|
CSCef39465
|
Symptom: When the cell rate on one of the VISM connection exceeds its PCR value, HEC Errors and Invalid OSF cell counters starts incrementing on all of the connections on the VISM card.
Conditions: This problem happens only in AAL2 trunking mode and with subcell multiplexing on.
Workaround: Having a sufficient PCR value on all the VISM connections so that the cell rate on any of the connections exceeds the PCR value is the only solution.
|
CSCef55005
|
Symptom: When running high traffic load scenarios with eight fully loaded E1 spans in VoIP switching mode, traffic might include upspeed to G.711, clear channel, or nailed up G.711 voice connections.
Packet loss might be encountered on occasion.
Conditions: This symptom occurs when concurrent traffic load of G.711 or clear channel with VAD off is sustained on lines with greater than 220 DS0s.
Workaround: For G.711 use VAD on because this issue does not occur with VAD on. Currently for clear channel the recommendation is not to load more than seven spans when utilizing 3.3 release.
|
CSCef55425
|
Symptom: Path confirmation failures—G.729a codec, adaptive jitter delay.
Conditions: At 11 calls per second, 3% of the voice calls fail with path confirmation errors (subsequent).
VISM configuration is ISDN-G729a with template 1. Jitter buffer is adaptive with initial delay set at 60 ms.
Workaround: Configure fixed jitter buffer delay of any value should resolve this problem for G.729a codec.
|
CSCef69692
|
Symptom: Mibwalk stuck in loop on catsAal2PvcHistoryTable.
Conditions: Multiple PVCs with multiple bucket interval updates for statistics causes this symptom to occur.
Workaround: No workarounds exist for the mibwalk. Except, run the mibwalks right after a card reset.
Note SNMP gets for objects within the table work correctly.
|
CSCef72611
|
Symptom: Path confirmation failures with CCD calls and VISM 3.1(3.x).
Conditions: Voice quality degrades (hiss) when running Clear Channel codec when the originating and terminating VISM cards are running different images, for example 3.1.3.x and 3.2.x.x.
This problem is not seen with any other codec or when running the Clear Channel codec on both VISM cards that are running the same version.
Workaround: Configure VISM to utilize a different codec during upgrades. And/or upgrade both VISM cards to the same version before running Clear Channel voice traffic.
|
CSCef81423
|
Symptom: BTS VoIP Switch T1 CAS 15 CPS load causes card resets.
Conditions: This problem exists only during CAS call load. VISM supports call rates up to a maximum call load of 10 cps.
Workaround: Ensure the call rate for a fully loaded VISM card that is configured for CAS voice traffic does not exceed the supported rate of 10 cps.
|
CSCeg47932
|
Symptom: 64 character VISM domain name causes VISM card to hang.
Conditions: After adding a 64 character VISM domain name using the cnfvismdn command, the card resets. When the card becomes active and you execute the dspvismdn command, the response shows (null) instead of the vism domain name.
If you try to execute the cnfvismdn command again, the prompt hangs indefinitely.
This problem is similar to caveat CSCee68257, regarding the call agent domain names instead of the VISM domain name.
This symptom occurs on VISM cards with Release 3.3 and a 64 character VISM domain name.
Workaround: Clear the configuration and enter only vism domain names with a maximum length of 63 characters.
