(Optional) Enables or disables idle code suppression for the CID. It can be one of the following values:

•1 = On

•2 = Off (Default)

payload-type

(Optional) Assigns the payload type. I can be in the range from 0 to 255. Default = 256.

Note If you do not use the payload-type argument to assign the payload type, the dynamic payload is set to the static value of the DSPs codec type.

Command Modes

VoIP switching/trunking

Usage Guidelines

The G.723.1 codecs are supported for VISM-PR cards and are not supported for VISM cards.

Examples

The following example shows that the RTP trunking connection 26 is configured (modified) with G.726/32 codec type. VISM is also configured to send and receive packets and has a 20-ms packetization period, a bearer precedence of 3, a bearer ToS of 1, with VAD enabled, and a 400-ms VAD holdover time. Also, ECAN, CAS, DTMF tone transport, idle code suppression for CID, and redundancy are enabled, and the 255 payload type is configured:

cnfvbdcodec

To configure the voiceband data (VBD) upspeed codec on the current VISM card, use the cnfvbdcodec command in the VoIP switching/trunking operating mode.

cnfvbdcodec upspeed-codec payload-type
Syntax Description

upspeed-codec

Upspeed codec. It can be one of the following values:

•1 = G.711u (Default for T1 VISM cards)

•2 = G.711a (Default for E1 VISM cards)

•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-type

Assigns the payload type—provides a mechanism for a codec to upspeed using a particular payload type. I can be in the range from 0 to 255. Default = 256.

Command Modes

VoIP switching/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. In this case, an actual downspeed would be performed.

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 clear channel, the codec is not used in the fax/modem upspeed session because VISM cannot detect any tones using clear channel.

AAL2 modes obtain the upspeed codec from the AAL2 profile table. AAL1 does not support compression and therefore does not require upspeed.

The G.723.1 codecs are supported for VISM-PR cards and are not supported for VISM cards.

Note Cisco recommends that you do not use upspeed-codec argument values 5 or 6 with this command.

Examples

The following example shows that the VBD upspeed codec is configured as G.711u and the 255 payload type:
cnfvbdcodec 1 255

Limitations and Restrictions

The following limitations and restrictions are valid for software Release 3.1(0) for VISM/VISM-PR:

•Software Release 3.1(0) for VISM/VISM-PR requires you to use 64 Mb VISM cards or VISM-PR cards exclusively.

•The switched AAL2 PVC operating mode is not supported in software Release 3.1(0) for VISM/VISM-PR.

•Cisco recommends that you use the cnfcodecjtrdelay command to configure the jitter-delay argument to 20 msec when using DSP firmware versions 3.4 and 3.6.

•Table 9 describes the design constraint which is identified in software Release 3.1(0) for VISM/VISM-PR.

Table 9 Known Design Constraint

DDTs Issue

Description

CSCdv37382

The addcid command can put VISM into the fail state. If non-AAL5 cells are sent to an AAL5 PVC of VISM, this can cause the VISM SAR chip to hang and VISM to go into failed state. This is because, in case of AAL5, the last bit of the Payload type indicator is used to determine which cell contains the end of that payload. All cells which have this bit set to 0 are held in the reassembly buffer until the cell with this bit set to 1 arrives. In case of non-AAL5 cells, this bit will never get set to 1, and ultimately this buffer will overflow. So, care should be taken that only AAL5 cells are sent to AAL5 PVCs of VISM.

Software Release 3.1(0) for VISM/VISM-PR introduces the new VISM-PR card. Complete the following steps to gracefully upgrade from VISM cards to VISM-PR cards. You must ensure that the VISM and VISM-PR cards have the minimum boot code version of vism_8t1e1_BT_3.1.00.fw.

The following versions of VISM software Release 3.1(0) are available:

•300.001.000.000—without CALEA

•003.051.000.000—with CALEA

Note You do not have to complete these instructions in order to use software Release 3.1(0) for VISM/VISM-PR; however, see the "VISM Features" section for a list of features that are not available to you if you do not perform this upgrade procedure.

VISM cards and VISM-PR cards use the same back cards. There are no new back cards introduced with this release. In the following procedure:

•Perform the firmware upgrade in the following procedure on the VISM cards; do not remove the VISM cards and replace them with VISM-PR cards at this time.

•Two VISM cards are involved in a redundancy group, initially with the primary card in the active state and the secondary card in the standby state.

•Old-rev refers to the firmware before the upgrade (2.2).

•New-rev refers to the firmware after the upgrade (3.1).

Step 1 Log in to the active PXM1 card (slot 7 or 8).

Step 2 Save the existing configuration as a contingency plan by entering:

savesmcnf <SM slot#>
This will save the existing configuration in the C:CNF directory. This file can be used during the downgrade procedure, if necessary.

Step 3 Execute the PXM install command:

install sm <SM slot#> <new-rev>
where:

SM slot# is the slot number of the primary VISM card and new-rev is the file name of the new firmware (for example, vism_8t1e1_300.001.000.000.fw).

This command causes the secondary VISM card to reset and come up in the standby state, running the new-rev firmware. The primary VISM card is unaffected by this command.

Step 4 Execute the PXM newrev command:

newrev sm <SM slot#> <new-rev>
where:

SM slot# is the slot number of the primary VISM card and new-rev is the filename of the new firmware.

This command causes the primary VISM to reset and the secondary VISM card to become the active VISM running the new-rev firmware.

Step 5 Execute the PXM commit command:

commit sm <SMslot#> <new-rev>
where:

SM slot# is the slot number of the primary VISM card and new-rev is the filename of the new firmware.

The two VISM cards are now back to their original condition except that both cards are now running the new-rev firmware.

Step 6 Log in to the active VISM card and use the display commands (dspendpts, dspcasvar, etc.) to confirm that the configuration has been preserved through the upgrade process.

Note For more than one primary VISM card in a redundancy group, ensure that the secondary card is in the standby state and repeat Step 4 and Step 5 for each VISM card in the redundancy group.

It is also recommended that a further verification be performed by making some minor modifications to the configuration, checking that the changes have been executed correctly, and then changing the configuration back again.

Note If the VISM card is not part of a redundancy group, Step 1 to Step 3 are sufficient.

VISM to VISM-PR Hardware Upgrade

Complete the following steps to upgrade your system from VISM cards to VISM-PR cards.

Caution 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 configure 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 your chassis.

Step 2 Install a VISM-PR card in the slot you removed the VISM card from in Step 1.

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 you removed the VISM card from in Step 4.

Step 6 Log into 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 insure that the correct card type is shown.

Step 7 Log into 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 and repeat the dspcd command to insure 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 your chassis.

Step 10 Install a VISM-PR card in the slot you removed the VISM card from in Step 9.

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 insure the correct card type is shown.

Installing VISM Software Updates with PXM1 Cards

Software Release 3.1(0) for VISM/VISM-PR provides a procedure for the graceful upgrade (one in which the existing VISM configuration is preserved throughout the upgrade procedure) from the earlier VISM 2.0 release.

Caution Installing VISM software updates from VISM Release 2.2 with CALEA to VISM Release 3.0 without CALEA is not graceful.

Caution Temporary traffic loss occurs during Step 4 and Step 5 of the VISM graceful upgrade procedure of the Upgrade Procedure for software Release 3.1(0) for VISM/VISM-PR.

Initial Conditions

The following initial conditions are required before the graceful upgrade procedure can be started:

•The MGX 8000 Series shelf must be configured with at least two VISM cards in a redundant configuration (refer to the add redundancy, addred, command in the MGX 8830, MGX 8850, MGX 8250, and MGX 8230 command references for more information).

•The VISM cards must be running VISM 2.0 and be configured to the desired configuration.

•The software Release 3.1(0) for VISM/VISM-PR must have been already downloaded to the MGX shelf.

•Ensure that you have the version of VISM software that supports CALEA, if you are using the CALEA feature.

Upgrade Procedure

Upgrades are available for the following releases:

•From VISM 1.5 to VISM 3.1

•From VISM 2.1 to VISM 3.1

•From VISM 2.2 to VISM 3.1

•From VISM 3.0 to VISM 3.1

Installing VISM Software Updates with PXM1E or PXM45 Cards

Complete the following steps to update the VISM software when you are using PXM1E or PXM45 cards in your MGX 8000 Series chassis:

Step 1 Log on 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 Use the saveallcnf command to save the existing configuration as a contingency plan.

Step 4 Use the loadrev sm-primary-slot-num new-rev command, where sm-primary-slot-num is the slot number of the VISM/VISM-PR card you to which you want to install the new software, and new-rev is the new firmware version number for the VISM software.

Step 5 Use the runrev sm-primary-slot-num new-rev command to execute the download.

Step 6 Use the commitrev sm-primary-slot-num new-rev command to commit the new download to the VISM/VISM-PR card.

You have completed the steps. Proceed to the VISM Boot Code Upgrade Procedure with PXM1E and PXM45 Cards.

VISM Boot Code Upgrade Procedure with PXM1 Cards

There is a new backup boot code change from VISM Release 2.2(0) to software Release 3.1(0) for VISM/VISM-PR. Complete the following steps to upgrade the new backup boot code when you are using PXM1 cards in your MGX 8000 Series chassis:

Note This procedure re-programs the VISM boot code for previous VISMs using the VISM runtime image version 1.0 to 2.0.

Step 1 Telnet to MGX shelf and cc to the VISM card.

Note VISM must be in the active state in order to update the VISM boot code.

Step 2 Access the server where the VISM boot code resides and TFTP the VISM boot code to the VISM card with the following procedure:

a. Type tftp <IP address of the MGX shelf>

b. Type bin at the tftp prompt.

Caution Ensure that you perform Step 2 b. If you to not perform Step 2 b. the boot code will be corrupted and not recoverable.

c. Type install [bt] [sm <slot>] <version> at the PXM prompt.

Caution Do not touch the VISM card until the status comes back ('Sent xxx bytes in yyy seconds'). Failure to follow this recommendation will corrupt the boot code and it will not be recoverable.

When the boot code is being written to PROM, you will see comments displayed at the VISM prompt. This is normal and expected behavior.

Step 3 Use the resetcd command for VISM from the PXM card for the latest boot take effect.

Step 4 Type the version command to verify the correct boot code.

Note Step 4 is optional.

You have completed upgrading the new VISM backup boot code.

VISM Boot Code Upgrade Procedure with PXM1E and PXM45 Cards

There is a new backup boot code change from VISM Release 2.2(0) to software Release 3.1(0) for VISM/VISM-PR. 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 VISM Firmware and Boot Code Download Procedure for PXM1E and PXM45.

Step 2 Log on to the PXM1E or PXM45 card.

Step 3 Use the burnboot sm-primary-slot-num new-rev command, where sm-primary-slot-num is the slot number of the VISM/VISM-PR card you want to upgrade and new-rev is the firmware version number of the new VISM software, to upgrade the VISM/VISM-PR boot code.

The VISM/VISM-PR card automatically resets and becomes active with the latest boot code image. You have completed the boot code upgrade procedure.

VISM Downgrade Procedure

Use this procedure to downgrade VISM software from software Release 3.1(0) for VISM to the earlier VISM Releases 3.0, 2.2, 2.1, and 2.0. By following the downgrade procedure described here, the configurations will be retained after downgrade.

Note It is important to note that 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 software from software Release 3.1(0) for VISM/VISM-PR to Release 3.0, 2.2, 2.1, or 2.0:

Step 1 If the VISM card is in a redundancy group, remove the redundancy.

delred <SM slot#>
Step 2 Download the old-rev firmware onto the MGX shelf.

Step 3 Execute the PXM clrsmcnf command:

clrsmcnf <SM slot#>
where:

SM slot# is the slot number of the VISM card to be downgraded.

The VISM card will be reset on executing this command. Wait for the card to come active.

Step 4 Execute the PXM restoresmcnf command:

restoresmcnf -f <filename> -s <SM slot#>
where:

The filename is 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.

The SM slot# is the slot number of the VISM card to be downgraded.

The VISM card will be reset again. When the card comes active, it will have the old-rev firmware running and will have the old configuration.

Step 5 Reconfigure redundancy group, if required.

CSCdx75181

VoIP trunking: With CALEA enabled, unable to add 248 RTP connections on a VISM E1 PR card.

If you are using the VoIP trunking operating mode on a VISM PR E1 card, with CALEA enabled and you try to add 248 RTP connections on two cards, one with CALEA enabled, the other with CALEA disabled, the result may be that on the card with CALEA enabled some of the connections seem to utilize more than 300 + 5% (RTCP) = 315 cells.

CSCdx76297

CAC also needs a minor change for CALEA VAD on calls.

CSCdx84300

While running calls at a high rate with RSVP, the VISM card may crash.

CSCdx86422

VISM does not respond to AUEP if mgcp protocol version mismatch.

CSCdx88658

Headline: The ECAN should be configured to bypass for COT tones.

Conditions: 2010 Hz COT tone is received from the TDM side on an endpoint with ECAN enabled.

Symptom: The echo canceller does not bypass for 2010 Hz COT tone (as well as other COT tones).

Workaround: None.

CSCdx90362

Symptom: IP_FREE_MESSAGE appears on HOST shellConn.

Condition: Problem is seen under heavy control traffic loads. In one particular test bed, due to misconfiguration bearer data is fed in control LCN and this problem shows up.

Workaround: Code is fixed to deal with this problem. To avoid running in this problem keep the control traffic low (6-7 calls per second).

CSCdx90604

HIMR: Bearer failing completely for AAL1 grooming.

CSCdx91260

HIMR: The clrrtpcnt command does not clear RTP packet loss counter for trunked cons.

CSCdx94130

Symptom: If DTMF digits with an on time of less than 45 ms are sent, the VISM randomly fails to detect some of the digits.

Condition: Calls may fail if a network element sends DTMF digits with short durations.

Workaround: If possible, use DTMF digits with ON time greater than or equal to
45 ms.

CSCdx96032

The t38T30ECM object is missing in TFTP file on VISM-PR.

CSCdy00014

VISM 2.2 VDNS is broken if you cnfdnssrvr, resetcd, cnfdnssrvr again.

CSCdy00491

Symptom: IP connectivity to VISM is lost. Ping does not work on VISM and MGCP messages do not reach VISM.

Conditions: Occurs under heavy load from DM (RSVP), and from HOST (CC,IP).

NY: VISM cards go to the failed state when high rate E1 SS7 calls are made.

CSCdy23462

VISM resets after PXM45 switchcc with AAL2 SVC calls.

CSCdy23876

Symptom: When a call agent is setup to send and request DTMF digit notification, the VISM does not notify the call agent when it receives DTMF tones, and does not send out DTMF tones when the call agent notifies the VISM of DTMF digits.

Workaround: DTMF Relay does work without call agent notification; however, if interworking is involved. (H.323 / SIP interworking) then call agent notification is required. In this case DTMF digits can still be sent in-band but only if a noncompression codec is used.

CSCdy32004

New t38 MIB t38T3ECM is shown as ? for the dspt38params command.

CSCdy32628

NY: Announcement StopPlay request does not stop announcement.

CSCdy62539

MGCI messages with improper versions handled incorrectly in VISM.

CSCuk34707

When a call agent is setup to send and request DTMF digit notification, the VISM does not notify the call agent when it receives the DTMF tones, and does not send out DTMF tones when the call agent notifies the VISM of the DTMF digits. DTMF Relay does work without call agent notification, however if interworking is involved H.323/SIP interworking), then call agent notification is required. In this case DTMF digits can still be sent in-band but only if a noncompression codec is used.

DDTs Issue

Description

CSCds66369

Title: VISM telnet sessions lock, unable to cc to card until reset.

Description: The VISM card allows up to two sessions. Both of these sessions have become locked, which prevents the user from being able to cc to the card. This condition has been reported twice and is not reproducible in the lab.

Workaround: Reset the card.

CSCdt85106

Title: G.726-16k, 24k and 40k cannot be configured as Vbdcodec.

Description for VISM 2.2: G.726-16k, G.726-24k, and G.726-40K should not be configured as Vbdcodec for upspeeding during fax/modem calls. This feature is not available in VISM2.2 release.

Workaround: If configuring with VISM CLI commands, do not configure G.726-16k, G.726-24k, and G.726-40K with cnfvbdcodec. If configuring with SNMP, do not configure G.726-16k, G.726-24k, and G.726-40K for the vismUpspeedCodec MIB object.

Description for VISM 2.1: VISM does not allow G.726-16k, G.726-24k, and G.726-40K to be configured as Vbdcodec for upspeeding during fax/modem calls.

Workaround: None.

CSCdx24153

OAM cells drop in AAL2 trunking with G.711u codec, and VAD disabled in combination with VISM-PR E1 cards.

CSCdx65569

AAL2 SVC upspeed to clear channel fails when there are more than 24 CIDs.

AAL1 SVC-DSP failed to detect tones in AAL1 encapsulation. Mid-call DTMF is not working for AAL1 SVC grooming solution. Tones are transmitted to the other end instead of to the call agent.

CSCdx72468

DTMF relay fails between the 5400 and VISM.

CSCdy26382

Headline: VISM encapsulates UDPTL for T.38 over RTP.

Symptom: T.38 Fax will not be successful when VISM interoperates with other gateways like AS5400.

Conditions: VISM wrongly encapsulates the T.38 data packets (UDPTL) over RTP instead of directly encapsulating on UDP.

Workaround: None.

CSCdy36418

Title: VISM-PR card must be reset after initial installation into MGX shelf.

Symptom: Any VISM-PR card must be reset after initial installation into an MGX slot. Although the PXM displays the correct card type for the VISM-PR card (using dspcds command), when logged into the actual VISM-PR card, the dspcd command displays the card type as a VISM legacy card instead of a VISM-PR card. The VISM-PR card must be reset from the PXM in order for the card type to be displayed as a VISM-PR card and also to function as a VISM-PR card.

Conditions: Symptom occurs on MGX 8850 with VISM-PR cards running release 3.1.

Workaround: Complete the following steps:

1. Replace VISM legacy card with VISM-PR card and wait for it to become active.

2. Once active, switch to the VISM-PR card using the cc command.

3. Execute the dspcd command to verify the card type (if problem exists it will be shown as a VISM legacy card).

4. If shown as a VISM legacy card, reset the VISM-PR card from the PXM using the resetcd <slot#> command and wait for it to become active.

5. Once active, switch to the VISM-PR card and execute the dspcd command once again to verify that the card type is now displayed as a VISM-PR card.
