Cisco IOS Release 12.1(3a)XI supports the Cisco Catalyst 4000 Access Gateway module.

New Software Features in Cisco IOS Release 12.1(3a)XI

There are two new software features supported by the Catalyst 4000 Access Gateway module for Cisco IOS Release 12.1(3a)XI. Under the control of Cisco CallManager, the Access Gateway module can support conferencing and transcoding services.

The conferencing service allows an external Cisco CallManager to use the DSP farm to mix participants into multiple conferences. The conferencing service adds G.711 voice streams to form unicast conferences.

The Cisco CallManager controls the conference with Skinny Client Control Protocol (SCCP).

The conferencing service supports:

Ad hoc or meet-me conferences

Up to 24 channels or voice streams

Partitioning the 24 channels into a set of conferences is done at the Cisco CallManager.

A maximum of six participants per conference

A maximum of eight simultaneous conferences

G.711 a-Law or u-Law encoding only

The transcoding service allows an external Cisco CallManager to use the DSP farm to compress or decompress WAN packets of voice streams between G.723.1 or G.729a to or from G.711. G.711 is the uncompressed format for LANs.

The transcoding service supports:

Up to 16 full-duplex channels on 8 DSPs

G.711 a-Law or u-Law to or from either G.729a or G.723.1

Capability to revert to one of several backup Cisco CallManagers in case the main one fails

New Hardware Features in Cisco IOS Release 12.1(3a)XI

Cisco IOS Release 12.1(3a)XI supports the Cisco Catalyst 4000 Access Gateway module.

New Software Features in Cisco IOS Release 12.1(3a)XI

There are no new software features supported by the Catalyst 4000 Access Gateway module for Cisco IOS Release 12.1(3a)XI.

Important Notes

The following sections contain important notes about Cisco IOS Release 12.1(3)XI8 that can apply to the Catalyst 4000 Access Gateway module.

Tighten Screws on VICs and WICs

You must tighten the screws on the VICs and WICs mounted on the Access Gateway module. If the screws are not properly tightened, the VIC or WIC may malfunction.

TDM Clocking

The TDM clock reference on the Access Gateway module can be derived from one of seven sources. These are the free running on-board clock and two recovered clock sources from each VIC slot that contains an E1/T1 card.

The default reference is the on-board clock. The frame-clock-select command can be used to select one of the E1/T1 ports as the primary reference. This command can also be used to select up to 3 prioritized backups that can be used if the primary clock fails. Switch over to a backup source is non-revertive, the system does not switch back to a higher priority clock if it recovers after a failure.

The command has the following syntax:

[no] frame-clock-select priority E1/T1 slot/port

The clock source with priority 1 is the primary reference and the clock with priority 4 is the lowest priority backup.

The clock reference selection using the frame-clock-select command is independent of the clock selection between line or internal on an E1/T1 controller. Framing and CRC errors due to clock slips may be observed on E1/T1 interfaces if the on-board clock is used as the reference.

Need to Support 56 Kbps Operation for Slot 3 WIC

The 8260 Rev1A device, which is being used in the Access Gateway module hardware, has a defect that can cause data corruption when configuring the MCC SI Ram for 2 entries (7 bits forming the 56kbps channel and 1 bit being discarded).

As a workaround, 3 SI RAM entries would have to be used, but the Access Gateway module does not have enough room available. Therefore, only 64kbps channels will be supported on the Access Gateway module.

If absolutely required, we could implement this feature in Access Gateway module slots 1 and 2 using the SCCs and limit it to 2 channels or super-channels per Access Gateway module slot. This requires more design work and will not be addressed unless really needed.

Customers that need 56kbps should use the WIC-56K4 WIC.

Caveats

Caveats describe unexpected behavior or defects in Cisco IOS software releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious.

This section contains only open and resolved caveats for this current Cisco IOS maintenance release.

All caveats in Cisco IOS Release 12.1(3) and Cisco IOS Release 12.1(3)T are in Cisco IOS Release 12.1(a)XI8.

For information on caveats in Cisco IOS Release 12.1, see Caveats for Cisco IOS Release 12.1, which lists severity 1 and 2 caveats and is located on CCO and the Documentation CD-ROM.

Open Caveats—Release 12.1(3a)XI8

There are no open caveats specific to Cisco IOS Release 12.1(3a)XI8 that require documentation in the release notes.

Resolved Caveats—Release 12.1(3a)XI8

Basic FAX is not working in IP Telephony mode when using the FXS/G.711 interface.

CSCdr79627

Before erasing a file from the flash file system, all telnet sessions to the Access Gateway (except the one from where the erase command will be executed) must be closed. Otherwise a system crash might occur.

CSCds02511

Fast switching is disabled on serial interfaces when IP RTP header compression is configured.

CSCdr94851

The show voicecard conference and show voicecard transcode commands can be inaccurate on extremely busy networks.

During periods of heavy usage, when calls are repeatedly connected and torn down, problems are encountered if you perform the show commands for transcoding or conferencing.The conference bridge or transcoder resource might have been released and then reused.The results are an incomplete display of the actual resource.

There are also times when the console gets stuck in a loop when trying to track an invalid resource.

CSCds02576

Caller ID is not supported on analog and digital ports (T1CAS and Analog FCS) in this release.

CSCds06790

When the conference bridge resource limit of 24 conferees is reached, the twenty-fifth conferee causes the conference originator to be dropped. The conference originator is also dropped when the maximum users on a conference bridge is extended beyond six.

CSCdr76149

In IP Telephony mode, the Access Gateway module only supports two codecs: G711u and G711a. The default codec appears as G729r8. The codec needs to be set to G.711 using the command line interface.

CSCds08253

Hook-flash does not work properly.

CSCds18197

The Access Gateway module does not support fxs-ground-start signalling in ds0-group command. See the following example:

CSCds17582

During normal IP gateway operation, T1 CAS and analog FXS work fine. But if a VoIP call is placed over the network and requires hardware transcoding, the voice interface stops working. Symptons are no dialtone from Chopin, signaling still goes through, but no talk path. This happens as long as one hardware transcoded call is up. This condition disappears once the transcoded call is released.

CSCds18197

The Access Gateway module does not support fxs-ground-start signalling in ds0-group command. See the following example:

Gateway(config-controller)#ds0-group 0 time 1 type ?

Need to support 56kb/s operation for slot 3 wic.

Reason for this action:

The 8260 Rev1A device (which is being used in the FCS Access Gateway module hardware) has a defect that can cause data corruption when configuring the MCC SI Ram for 2 entries (7 bits forming the 56kbps channel and 1 bitbeing discarded). As a workaround, 3 SI RAM entries would have to be used, but the Access Gateway module does not have enough room available. Therefore, only 64kbps channels will be supported on the Access Gateway module.

If absolutely required, we could implement this feature in Access Gateway module slots 1 and 2 using the SCCs and limit it to 2 channels or super-channels per Access Gateway module slot. This requires more design work and will not be addressed unless really needed.

Customers needing 56kbps should use the WIC-56K4 WIC.

Open Caveats—Cisco IOS Release 12.1(3a)XI
