The software no longer lists the individual executable file (.EXE) version numbers in the Software/Firmware Configuration screen. A "—" character in the File Version column signifies that the file version matches the system software release, for example, Version 5.2. If a version number appears in the File Version column for an .EXE file, it is strictly for reference purposes; it does not appear in the Software/Firmware Configuration screen.

The checksum values for .upg files (protocol files) are displayed by accessing the Display File screen. Go to Maintenance Menu > Disk Utilities > Display File, and type: c:boot/<filename>. The .upg file checksum value is displayed in the first four bytes of the second row.

The VCO.MIB file is not installed on the switch; it is intended for the SNMP host system.

New and Changed Information

VCO/4K system software Version 5.2(2) is a maintenance release which includes several caveat resolutions. Refer to the "Caveats" section for more information on resolved caveats.

This release contains an enhancement for the Password Configuration screen, which allows you to change SNMP read and write community strings of up to ten characters. See the "Changeable SNMP Community Strings" section.

Diskettes containing Version 5.2(2) system software are not provided. You must complete the procedures in the following sections to make your diskettes:

Changeable SNMP Community Strings

The Password Configuration screen allows you to change SNMP read and write community strings with the previous release, VCO/4K system software Version 5.2(1). The Version 5.2(2) release increases the password length from eight to ten uppercase and/or lowercase alphanumeric characters.

Complete the following steps to configure SNMP community strings:


Step 1   Access the Password Configuration screen. Refer to the Cisco VCO/4K System Administrator's Guide for more information on the Password Configuration screen.

Step 2   Delete the following two usernames:

Step 3   Add and save the two usernames you deleted in Step 2.

The password of the snmpget serves as the SNMP GET community string, and the password of the snmpset serves as the SNMP SET community string.

Step 4   Establish passwords for the usernames added in Step 3. Refer to the Cisco VCO/4K System Administrator's Guide for instructions.


Note    Passwords must consist of up to ten uppercase and/or lowercase alphanumeric characters. If you type a password more than twelve characters, the tenth character is overwritten until you stop typing. Follow all existing user password restrictions described in the Cisco VCO/4K System Administrator's Guide.

The passwords are displayed as asterisks (*) on your screen.

Step 5   Change your passwords as often as necessary.



The SNMP community string configuration is complete. The VCO/4K system compares the passwords of the snmpget and snmpset usernames with the community strings given by incoming SNMP request messages—community strings used by the network management station (NMS) for GET and SET commands.

Changeable SNMP Community Strings Restrictions and Limitations

Limitations and Restrictions

If you are using the VCO/4K product for Communication Assistance for Law Enforcement Act (CALEA) conferencing, you must administratively detach each CALEA one-way port when the CALEA conference is completed. CALEA one-way conference ports remain in the Class of Service (COS) state of 2C if you do not detach them, which makes them unavailable for other calls. Refer to the Cisco VCO/4K System Administrator's Guide for information about administratively detaching ports.

Table 3 lists the design constraints which have been identified in VCO/4K system software and related software. Unless noted, these limitations and restrictions apply to all Cisco VCO/4K releases up to and including 5.2(2). Cisco Systems currently has no plans to address the following known design constraints.

Table 3   Known Design Constraints up to and Including Version 5.2(2)

DDTs Issue  Description 

Do not pull the active side NBC3 on an operating production switch. If you pull an active NBC3, it can impact traffic and the system will generate errors. If you suspect a problem with an NBC3 card and you wish to remove it, first switch sides to make it the standby side.

The ICC and SPC automatically reset after downloads. After a download to the ICC or the SPC, the card resets itself for the new download to take effect.

The system does not allow the operational mode to be set back to standard once it has been set to extended. This is due to larger values which could be set in extended mode and are not valid in standard mode.

The mode is stored in one of the database files. If you must return to standard mode during testing, do so by reverting to the saved database files which were copied before you set the extended mode.

CSCdm18135

If a resource group contains SPC-CONF, the system hunts by means of the Rotary method only (regardless of whether you select Rotary or Cyclic in the Hunt Type field from the Resource Group Summary screen).

CSCdm45047

The Disk Utilities screen option I, Format Disk, is unavailable for users of system software V5.x and higher. If you attempt to format a floppy disk in the A:/ drive, the "Formatting A Drive Is Not Permitted" message appears.

CSCdp49217

FTP hangs while running FTP scripts to the VCO.

CSCdp78129

ICC quiet tone: the administration diagnostic screen indicates that the port is attached/listening to 4C0, when it is actually generating the quiet tone itself and is not attached to 4C0.

CSCdp84909

The VCO receives alarms FRM506/FRM531 under the rare circumstances of the SWI buffer not being allocated for sending messages to the NBC, during very high volume traffic. Loss of traffic may result.

CSCsf31137

After a warm start, the system sends a $DC report to start call processing before IPRC prompt downloading is complete.

CSCsf41717

Avoid using the Software/Firmware Configuration screen to view the contents of floppy diskettes (device A:).

CSCsf51960

If you use an Ethernet system host interface with up to four hosts and high loads, the system may fail. Higher loads may support even fewer host connections. Use minimum host connections for high load switches.

CSCsf52581

Aux1 alarms triggered by the hardware (power supply, fan unit, or ring voltage failure) are not displayed on the System Alarms Display screen. Therefore, remote users cannot determine if a major hardware alarm is set.

CSCsf62790

A load seize on inpulse rules with record and speak tokens at 22 seizures causes IPRC cards to go OOS.

CSCsf62917

There is a mismatch between the online and diskette disk utilities. Underscores and special characters are not supported in directory and file names.

CSCsf62982

You do not get major alarm ALM011: No Hosts Available when all hosts connections are lost if TeleRouter is enabled. TeleRouter causes this problem. If TeleRouter is disabled and all host connections are lost, the alarm appears.

CSCsf63022

TeleRouter Routing Action ($D5) reports do not appear in the system trace file, but they are sent to the host.

CSCsf63245

If you attempt to update the gateway routing tables before you install and enable Ethernet, the gateway routing tables get corrupted.

CSCsf63261

If you use SNMP to configure resource groups on redundant systems, the port.tbl file gets corrupted and ports are missing from the resource groups.

CSCsf63398

If you add or delete a tone generator card while another tone generator is outpulsing, the switch may be unable to do further outpulsing and may even fail.

CSCsf84601

Can't delete large files from administration console.

CSCsf84771

A shutdown to the system results in a reboot. If you need to prevent a reboot, you must follow one of the following workaround procedures:

  • Remove the Combined Controller on a VCO/4K. Rebooting attempts are prevented.
  • Reboot the system from a floppy disk. The system enters and remains in the installation state, and prevents further reboots.

CSCsf84962

All inpulse rules are aborting on port $47F, when using the physical address $47F as a trunk resource. Inpulse rule aborting occurs because $47F is adjacent to the tone card. Do not use physical address $47F.

CSCsf85137

If a DSP SRM is not physically installed on the SPC, but the DSPs are configured in the database, the system displays the SPC with a status of M (maintenance) rather than the expected O (out of service) status.

CSCsf85214

Spans that have been taken OOS before a reboot must be manually taken OOS after the reboot is complete. It is also recommended that the system is not run with cards defined and OOS; remove cards from the database. This workaround will improve overall performance.

Important Notes

This section contains important information for operating the VCO/4K system efficiently. The following sections are included to enhance configuration and performance:

Mandatory Database Conversion for Upgrade from Version 5.1(4) and Lower

If you are upgrading from VCO/4K system software Version 5.1(4) or lower, you must complete a database conversion immediately after upgrading to VCO/4K system software Version 5.2(0) and higher. Refer to the Cisco VCO/4K Software Installation Guide for database conversion procedures.


Note   The database conversion is performed by the system without the usual advisory system messages.

Live Upgrade

You can use Live Upgrade to upgrade to system software Version 5.2(2); however, refer to the following two sections for version-specific workaround procedures.


Caution   Do not operate conferences on the VCO/4K system while performing a Live Upgrade. Failure to follow this guideline may result in loss of calls. Ensure that the host is not sending Conference Control ($6D) commands to the VCO/4K system during the system reset/file synchronization phase of the Live Upgrade procedure. Refer to Step 5 through Step 11 in the "Perform a Live Upgrade" section of the Cisco VCO/4K Software Installation Guide for more information.

Live Upgrade Procedures from Version 4.2 and Higher

Complete the following steps to use Live Upgrade if you are using system software Version 4.2 and higher. This procedure is a workaround for DDTs issue CSCdp23217—Live Upgrade failure with a Process Event Handler.


Caution   If you are using system software from Version 5.0.0.25 through Version 5.1.0.26, you must complete the following steps, and the steps in the "Live Upgrade Procedures from Version 5.0.(0.25) through Version 5.1.(0.26) with SPCs" section, so that you do not lose all calls.


Caution   Do not access the Software/Firmware Configuration screen at any time during Live Upgrade procedures. Failure to follow this instruction results in Live Upgrade failure. Proceed to Step 1; do not deviate from these procedures.


Step 1   Boot the standby side of the switch.

Step 2   Wait for file synchronization and perform a switchover.

Step 3   Boot the new standby side and wait for file synchronization.

Step 4   Follow the Live Upgrade procedures in the Cisco VCO/4K Software Installation Guide.



Live Upgrade Procedures from Version 5.0.(0.25) through Version 5.1.(0.26) with SPCs

Complete the following steps to use Live Upgrade from system software Version 5.0.(0.25) through Version 5.1.(0.26). This procedure prevents DSP failure on switchover and is a workaround for DDTs issue CSCdm22671.


Caution   Follow this workaround procedure when using Live Upgrade from Version 5.0.(0.25) through Version 5.1.(0.26). Failure to do so will result in the loss of all calls that require SPC resources. Use this procedure to minimize the volume of lost calls, limiting them to calls that are active on the SPC and that are taken out of service in order to reflash.


Step 1   Load the new SPC.DWN on the active side of the system.

Step 2   Take one SPC out of service (OOS).

Step 3   Place the same SPC in the active state.

Step 4   Wait for the download to complete and all DSPs to become active on the SPC.

Step 5   Repeat Step 2 through Step 4 for all other SPCs, one at a time.

Step 6   Follow the Live Upgrade procedures in the Cisco VCO/4K Software Installation Guide.



ICC-T1 ISDN Span as Primary Timing Source

When an ICC-T1 ISDN span is configured as the primary timing source, the incoming clock on the ICC-T1 ISDN fails to synchronize if you are upgrading from an existing database—prior to system software Version 5.1(1)—to a new database in VCO/4K system software Version 5.2(1).

To utilize your existing ICC-T1 ISDN (NI2, 4ESS, 5ESS, NTI, NTT) span as the primary timing source, complete the following steps when you upgrade to 5.2(2).


Note   You do not need to perform the following procedure if you are adding a new T1 span as the primary timing source to the database or if you are currently running system software Version 5.1(1) or higher.


Note   When you upgrade your software to 5.2(2), Cisco Systems recommends that you perform this procedure on the ICC-T1 ISDN spans configured as the primary and secondary timing source.


Step 1   Take the existing ICC-T1 ISDN span, configured as the primary timing source, out of service (OOS).

Step 2   From the ICC ISDN Span Configuration screen, perform the following steps:

    a. Change the REF CLOCK field parameter from LOOP to 1544.

    b. Press Enter.

    c. Change the REF CLOCK field parameter from 1544 to LOOP.

    d. Press Enter.

Step 3   Return the ICC-T1 ISDN span (from Step 1) back in service.

Table 4   Resolved Caveats for Version 5.2(2)

DDTs Issue  Description 

CSCdm94205

SPC does not know when DSPs are dead when using MRC.

CSCdr49239

Adding 8 SPC-DTMF, SPC-CPA, or SPC-MFRC types to a resource group will produce the Alarm Set For Loss Of ALL message for that type of resource. You must add 7 or 9 DSPs to service circuit resource groups to work around this issue.

CSCdr71390

Using the Next Screen key followed by the Previous Screen key with the Card Maintenance screen results in bypassing the previous screen and displaying the first screen.

CSCdt41477

If SPC-CONF resources are used to set up a conference, voice path problems and voice quality degradation occurs after multiple switchovers. Use SPC-ENHCNF instead of SPC-CONF or reseat the SPC as a workaround for this issue.

CSCdt83631

The Subrate Connection Display screen fields are not large enough to enter the rack, level, slot, group, and span of ICC cards. The Display Filter field, and when the command ADD is selected, the Source and Dest Fields are affected—the Slot field is not large enough to enter the group and span of an ICC card.

CSCdu28879

The Card Alarm Display screen shows Remote Alarm and D channel Failure on normal ICC-E1 CAS spans that have carrier failure and OOF. On ICC-T1 CAS spans, the Card Alarm Display screen shows Remote Alarm, D channel Failure, and Card Failure when it should show Carrier Failure and OOF. Carrier failure and OOF are shown in the Display Card Data screen under the Diagnostics menu and these same alarms should show in the Card Alarm Display screen under the Maintenance menu.

CSCdu34234

When a Voice Port Control ($6C) command is issued to play a voice prompt, in conjunction with an outbound ISDN port, and before the voice prompt stops playing—no Voice Port Status ($DE) report sent—and another $6C command is issued to stop the voice prompt, the voice prompt will stop but will leave the ISDN port in the CP_ATT state instead of returning it to the CP_SETUP state. Both the ISDN Port Control ($49) command issued to cross connect this port to another port or a Conference Control ($6D) command issued to add it to conference are rejected. The VCO/4K system returns the network status byte $20 or $1E.

CSCdu65580

You may encounter a call chain corruption on the standby side while running a call transfer load on the VCO/4K. This has the potential to reset the standby side. The active side is not affected. A call transfer load consists of a complex call scenario where two calls (a call started by using a virtual incoming port and an incoming call from the network) are interchanged using the Change Incoming Port ($6B) command on the VCO/4K.

CSCdu74201

When using an inbound SS7 port to receive a call and making an outbound call using an SS7 port and then connecting them together, two start records are used and kept for the length of the call instead of one start record. This reduces the total amount of start records available for call processing.

CSCdu75941

The system may stop PRI/N downloads after 10:03 minutes, which may lead to repeated download attempts in order to complete the download process.

CSCdu85266

The Standard DTMF Digit ($D1) report is reporting the incorrect (according to the published documentation) values for *, 0, and #. It is reporting the values documented in the Enhanced D1 report.

CSCdu85623

If the Change Port Status ($90) command is sent to deactivate a PRI port which is in the CP_STAB state, the associated NBC $15 message will inappropriately identify ports 19 and 21 of a E1 PRI NET5 span as D channels. This may result in the card reporting a parsing error to the system software and cause the following message to be entered in the logfile: PRI INTERNAL ERROR CODE 1,15.

CSCdv05076

Both sides crashed causing core file on the active side.

CSCdv16247

A single-span PRI/N card (PRI/N, NTTPRI) added under generic 5.2.1 will not clear alarms for newly added spans. You must change the span framing type to D3/D4 and then back to ESF, which resets the framing type to 2 (which is ESF).

CSCdv19403

A glare condition on ISDN PRIs configured as USER (access type) causes the start record/end record (SR/ER) to remain allocated to the virtual port (the port originally involved in the outbound) and is never de-allocated. This SR/ER is never assigned to a new call and the system may run out of SR/ER as the number of "stuck" records increase with the glare condition.

CSCdv63138

SNMP functions (such as gets) do not work on SPC DSPs above 4; attempts return a null response.

CSCdv65189

Using the Conference Control ($6D) command to delete a talk-only port from a second conference is rejected with a network status byte of $29 (internal error), and the port becomes unusable. The Display Port Data Screen displays the port in the first conference, the second conference port is not displayed.

CSCdv69069

A T1/E1 you configure as your incoming timing source may return as your external timing source.

CSCdv69993

SNMP trap on alarm 42 occurs with ICC and SPC cards.

CSCdw01835

Variable length community strings on VCO/4K SNMP. There is a limit of eight character passwords and a processing speed issue with moderate use of SNMP.

CSCdw16770

When a VCO/4K is configured with two SPCs and both have SPC-DTMF, SPC-CPA, and SPC-CONF DSPs configured and active, you may get the following messages when you unseat or take out of service one of the SPCs:

  • ALM050: Loss Of All DTMF Receivers
  • ALM047 Loss Of All Call Prog. Analyzers
  • ALM078: Loss Of All CONFERENCE ports

These messages occur even though they are invalid, due to the second active SPC retaining the same resources.

CSCdw16830

ICC-T1 COS A2, E&M signaling ports stuck in the CP_GARD state when an alarm is detected on the span. The ports remain in the CP_GARD state after the alarm clears. You must place the span in the out of service state and then place it in the in service state to clear this situation.

CSCdw25481

The counters for attempts and completions may not be correct in the Port Status screen of the Diagnostic Menu.

CSCdw40478

When you change the master timing from incoming to external, the VCO/4K may fail over to internal timing, yet the Master Timing Link Selection screen displays the current timing source as external. You must first set the master timing to internal, then change it to external.

CSCdw46077

The Port Supervision Control ($72) command does not work with ICC cards.

CSCdw49214

When a card with a port range around FF is activated, a master timing selection of external will fail over to internal timing. You must change the Master Timing back to External through either the Master Timing Link Selection screen under the Maintenance Menu or with a Change Active Controllers ($C0 02) command from the host. This workaround does not stop the VCO/4K from failing over to internal but restores the master timing to an external source.

CSCdw62289

SPC DSPs stop responding when running MF/DTMF digit collection.

Open Caveats

Table 5 describes possible unexpected behavior by Cisco VCO/4K Version 5.2(2). Unless noted, these caveats apply to all Cisco VCO/4K system software releases up to and including 5.2(2).

Table 5   Open Caveats up to and Including Version 5.2(2)

DDTs Issue  Description 

CSCdp64900

The SPC-OUTP fails to work the first time after defining in the database.

CSCdr39175

Single power supply causes Major alarm on fully populated switch.

CSCdr98769

VCO shows incorrect Alarm Occurrences MIB value (systemAlarmOccur).

CSCds21994

OID incorrect for VCO/4K.

CSCds24360

Changing protocol to Foreign Exchange Office Loop Start (FXOLS) on a span basis is not possible.

CSCds45890

When using an inpulse rule with the token TONE ENAB 3, there are intermittently inpulse rule aborts due to the generic not responding to a $4B command with a $4D report. When this happens, there is no dial tone played through the port.

CSCds89831

T309 Timer does not stop after D-Channel is reestablished following a reboot.

CSCdt05993

ICC-E1/NET5-UK goes out of service under load. This event is preceded by an ICC Congestion Alarm Clear message.

CSCdt51511

ICC revision level COAR drops all the existing calls when the card is set to maintenance.

CSCdu38965

Adding and deleting an IPRC to a Version 5.2 VCO/4K system database causes the following errors: FRM340, FRM503, and FRM510.

CSCdu48116

If a NOTIFY message from the network is received by the VCO/4K system and the ISDN state is active (10), the system passes the NOTIFY message to the host in bytes 26 through n of an ISDN Port Change of State ($EA) report. In all other states, the system ignores the NOTIFY message from the network.

CSCdv05327

The ICC downloads in system software V5.1.4, V5.2, and V5.2.1 produce an idle pattern of FF, which may cause an alarm indication signal (AIS) alarm. The ICC downloads should produce an idle pattern of 7F.

CSCdv67971

An entire ICC may stay out of service after a complete reboot of a VCO/4K system. You must unseat and reseat the ICC card to allow the card to enter the in service state.

CSCsf63269

The RELEASE DTG token does not work: The RELEASE outpulse rule token does not release the DTG/DTG2 and causes the system to log an error during inpulse rule execution.

CSCsf84766

Subrate error during Live Upgrade—from 4.2.0.23 to 5.0.51.24 a "Subrate RS ack numbers: expected ==0x2, got==0x1" error message was printed to the log.

CSCsf84879

Standby crash when SPCs added and modified using SNMP.

CSCsf85166

When the system is running in extended mode, the api_stat.c routine to format the rack, level, and slot in the $83 command from tokens does not work correctly.

CSCec52889

Problem:

When the host sends a $69 or $49 command with an empty IP field and the SPC-outpulse is used to complete the outpulsing, calls fail.

Workaround:

Avoid having the host outpulse an empty field the using the SPC-outpulse or direct the host to use a different outpulse rule to outpulse an empty field.
