The VISM/VISM-PR card prompt is displayed when you successfully log in to a VISM/VISM-PR card. It has the following format:

nodename.1.9.VISM8.a

The VISM/VISM-PR card prompt contains the following data:

•Name of the MGX 8000 Series platform to which you are connected

•Number of the shelf—always 1

•Slot number

•Card type

•Card state—active (a) or standby (s)

You have completed logging in to the PXM and VISM/VISM-PR cards and can now perform the mandatory initial VISM/VISM-PR card configuration.

Logging Out of VISM/VISM-PR and PXM Cards

To log out of the VISM/VISM-PR or PXM card, enter one of the following commands:

•bye

•exit

•logout

Using the Command-Line Interface

Command-line interface (CLI) commands can be followed by a string of required or optional argument identifiers and argument values.

For a list of commands in a particular category, type a ? followed by the prefix of the command.

nodename.1.1.VISM8.a > ? clr
Command Logging State Priority
-------------------- ------- ------ -------------------------
clralm No Any Group 1
clralmcnt No Any Group 1
clralmcnts No Any Group 1

clrsarcnts No Any Group 1
clrsarmsgcnt No Any Group 1
clrscrn No Any Any User
clrslipcnt No Any Group 1
clrtaskinfo No Any Service Group (-1)

If you do not know the syntax of a command, type the command name and then press Enter. The syntax displays with the parameter ranges.

nodename.1.21.VISM8.a > addlapdtrunk

ERR : incorrect number of parameters (not enough)

Syntax : addlapdtrunk "Line_Num Lapd_Rudp_Index"
Line_Num -- Value: 1 - 8
Lapd_Rudp_Index -- Value: 1 - 64

possible errors are :
Incorrect number of parameters

nodename.1.21.VISM8.a >

The entire string, from the command to the last argument value, is referred to as a command line. Spaces are used to separate all elements in a command line. Type the command and any necessary argument identifiers and argument values, and then press Enter.

Note You must press the Enter key at the end of each CLI command line to complete the command.

For example, the Add Endpoint command, addendpt, adds an endpoint to VISM/VISM-PR and has three required arguments. An endpoint defines one end of a connection. The addendpt command format is as follows:

nodename.1.21.VISM8.a > addendpt <endpt_num> <ds1_num> <ds0_num>

When you type a command, use argument values to represent the arguments. For example, to add an endpoint with number 10 on DS1 number 4 and DS0 number 3, you would use this command line:

nodename.1.21.VISM8.a > addendpt 10 4 3

Some commands require you to type an argument identifier before the argument value. For example, the Clear Alarm command, clralm, requires you to enter an identifier, -ds1, before the argument value. The clralm command format is as follows:

nodename.1.21.VISM8.a > clralm -ds1 <LineNum>

To clear alarms on line 4, you would use this command line:

nodename.1.21.VISM8.a > clralm -ds1 4

Configuring the VISM/VISM-PR Card

You must complete the following configuration tasks when you initially configure your VISM/VISM-PR card.

• Allocating Resources

• Configuring the TDM Side

Allocating Resources

To allocate resources—virtual ports, controller resources, and codec templates—to your VISM/VISM-PR card, complete the following step:.

Step 1 To add a virtual port, enter the addport command (no arguments).

This command adds an ATM port on a VISM/VISM-PR card. This command does not have arguments. When you add the ATM port, the bandwidth, VPI range, and VCI range are determined.

The VPI range is a single VPI value, the slot ID. The added port is not detected by the controller until you create a resource partition (see Step 3).

Step 2 To verify that the port was added successfully, enter the dspport command.

nodename.1.27.VISM8.a > dspport
Provisioned BW : 5651320 cps
Used BW : 0 cps
Available BW : 5651320 cps

Step 3 To specify the controller resources, enter the addrscprtn command.

nodename.1.28.VISM8.a > addrscprtn <controller_id>

Replace <controller_id> with the following values:

•1 = PXM1 (PAR)

•2 = PXM1E/PXM45 (PNNI)

A port supports only one controller at a time.

All resources of a port are associated with the resource partition you specify. When you add a resource partition, the associated controller detects the port as limited by the resource partition.

Step 4 To specify the codec template used with your VISM/VISM-PR card, enter the cnfcodectmpl command.

nodename.1.28.VISM8.a > cnfcodectmpl <template_number>

For the VISM card, replace <template_number> with one of the following values listed in Table 5-2.

Table 5-2 Codec Templates

Step 5 Type a y at the following message:

The card will be reset, do you want to proceed (Yes/No)? y

The card resets and returns the prompt.

Note Although the prompt indicates that you are accessing the VISM/VISM-PR card, once you type a character or press Enter, the session automatically falls back to the PXM card. Use the cc command to change back to the VISM/VISM-PR card.

Step 6 To display the codec you selected in Step 4, enter the dspvismparam command.

Replace <residualEchoControl> with one of the following values:

Note The value of 3 is omitted.

•1 = Cancel only

•2 = Suppress residual

•4 = Comfort noise

Note We recommend that you use Comfort noise.

Step 3 To specify the ECAN algorithm maximum tail length, enter the cnfecantail command.

nodename.1.28.VISM8.a > cnfecantail <lineNum> <maximumTail>

Replace <lineNum> with the value used in Step 1.

Replace <maximumTail> with one of the following values:

•24 ms

•32 ms (default)

•48 ms

•64 ms

•80 ms

•96 ms

•112 ms

•128 ms

Note Although the default ECAN tail is 32 ms, we recommend that you use 64 ms.

Step 4 To show the ECAN configurations for line 1, enter the dsplndsp command.

nodename.1.28.VISM8.a > dsplndsp <lineNum>

VismLineNum: 1
ECANEnable: enable
MaximumTail: 64 milliseconds
ResidualEcho: SuppressResidual

Configuring Connection Admission Control

Connection admission control (CAC) is a set of actions that ascertain if a connection request can be accepted or must be rejected.

By default, CAC is enabled.

Use the steps in this section to complete the following procedures:

•Define CAC parameters.

•Configure voiceband data policies for fax/modem carrier loss and fax/modem CAC failure events.

Step 1 To enable or disable CAC, enter the cnfcac command.

nodename.1.28.VISM8.a > cnfcac <enableFlag>

Replace the <enableFlag> with one of the following values:

•1 = Disable

•2 = Enable

Step 2 To ensure that CAC is enabled or disabled, enter the dspvismparam command.

Step 3 To enter card level CAC parameter values for voice activity detection (VAD) duty cycle and VAD tolerance, which are used in CAC algorithms, enter the cnfcacparams command.

nodename.1.28.VISM8.a > cnfcacparams <VAD_duty_cycle> <VAD_Tolerance>

Replace each of the above arguments with a value listed in Table 5-5. The following example shows the typical values for VAD duty cycle and VAD tolerance:

nodename.1.28.VISM8.a > cnfcacparams 61 100

Table 5-5 Parameters for cnfcacparams Command 

Parameter
Description

VAD_duty_cycle

VAD duty cycle is the ratio of speech and holdover duration to the total duration expressed as a percentage.

Holdover is the period after silence begins, and silence suppression is turned on. In VISM/VISM-PR, the holdover time is 250 ms.

A typical value for this parameter is 61 which means that 61% of the time is taken by speech and holdover. Range is 1-99. Default is 61.

VAD_Tolerance

VAD tolerance is the expression for VAD over-subscription drop ratio, where tolerance = 10000 x over-subscription drop ratio (expressed as a percentage).

A typical value for VAD tolerance is 100. Some examples are:

•10000 (tolerance) = 1% (over-subscription drop ratio)

•100 = 0.01% (default)

•10 = 0.001%

•1 = 0.0001%

Range is 0-10000.


Step 4 To specify card level default policies for a fax/modem carrier loss and a fax/modem CAC failure, enter the cnfvbdpol command.

Note This command is not applicable in the AAL1 switching mode.

nodename.1.28.VISM8.a > cnfvbdpol <sysCarrLossPol> <sysCacRejPol>

Replace the above arguments with the values listed in Table 5-6.

Table 5-6 Parameters for cnfvbdpol Command 

Parameter
Description

sysCarrLossPol

Card level carrier loss policy.

•1 = Revert to the previous codec.

•2 = Maintain the upspeed codec.

sysCacRejPol

Card level CAC reject policy.

•1 = Delete the connection.

•2 = Maintain the connection and revert to the previous codec.


Configuring Jitter Mode

You can dejitter the voice payload to improve the quality of the egress voice stream.

Note If your application uses the AAL2 trunking operation mode, changes to the jitter modes are affected only when you delete the CIDs and re-add the CIDs.We recommend that you use the fixed jitter mode for AAL2 trunking.

Complete the following steps to specify and configure jitter mode:

Step 1 To set the jitter mode, enter the cnfjtrmode command.

nodename.1.28.VISM8.a > cnfjtrmode <jtr_mode>

Replace <jtr_mode> with one of the following values:

•1 = Fixed. We recommend fixed mode if latency jitter is constant.

•2 = Adaptive. We recommend adaptive mode if latency jitter is variable.

Note This command changes the mode for all codec types.

Step 2 To display the codec delay mode and initial delay, enter the dspcodecjtrdelays command.

nodename.1.1.VISM8.a > dspcodecjtrdelays
codecType delay mode timestamp initial delay
