Configuring and Troubleshooting VWIC2-xCTE1-PRI Modules for Inbound ISDN Multilink PPP Data Calls

We have seen more and more customers are now moving away from traditional NM-xCTE1-PRI and HWIC-xCTE1-PRI modules which supports data and modem calls (not voice calls) to VWIC2-xMFT-T1/E1 modules which supports Data and Voice calls together on same PRI lines. We have seen increased deployment of VWIC2-xMFT-T1/E1 modules on Integrated Service Routers that supports voice and data calls on same PRI line.

This document describes how to configure ISDN PRI interfaces on VWIC2-xMFT-T1/E1 modules with PVDM2-xx to support data calls on multiservice access routers. This feature enables Multilink PPP data (dial-in, dial-on-demand routing [DDR], and DDR backup) and voice call traffic to occur simultaneously from the supported ISDN PRI interfaces.

Supported Modules

This feature supports the following modules:

–NM-HD

–NM-HDV2

–Onboard DSPs

•This feature is supported on the following voice cards:

–VWIC-XMFT-X interface modules

–VWIC2-XMFT-X interface modules

Note Data calls are supported only on the NM-HDV2-2T1/E1 and NM-HD-2V-E network modules, and the VWIC-2MFT-E1, VWIC-2MFT-T1 and VWIC2-T1/E1 voice cards.

Use the isdn switch-type ? command in interface configuration mode or global configuration mode to view the list of supported ISDN switch types. See the following example:

Router(config)# isdn switch-type ?

primary-4ess Lucent 4ESS switch type for the U.S.

primary-5ess Lucent 5ESS switch type for the U.S.

primary-dms100 Northern Telecom DMS-100 switch type for the U.S.

primary-dpnss DPNSS switch type for Europe

primary-net5 NET5 switch type for UK, Europe, Asia and Australia

primary-ni National ISDN Switch type for the U.S.

primary-ntt NTT switch type for Japan

primary-qsig QSIG switch type

primary-ts014 TS014 switch type for Australia (obsolete)

Restrictions for Integrating Data and Voice Services for ISDN PRI Interfaces

•This feature is supported only on C5510 DSP-based platforms.

•ISDN backhaul is not supported.

•This feature does not support modem calls.

•For platforms that support HDLC resources on the motherboard, the available on board HDLC resources are limited to 31 if all resources are not enabled.

•The Cisco 2801 platform does not support full channelized data or full integrated data and voice over T1/E1 PRI interfaces. However, data back up through one PRI channel, or one group of PRI channels for data backup, is supported on this platform.

•Only PPP with multilink is supported for multiple channels. HDLC is not supported for multiple channels.

•This feature is not supported from a BRI interface.

• following dialer commands are not supported with the integrated data and voice feature:

–dialer aaa

–dialer callback-secure

–dialer callback-server

–dialer dns

–dialer order

–dialer persistent

–dialer redial

–dialer vpdn

–dialer watch-disable

–dialer watch-group

–dialer watch-list

–dialer watch-list delay

Use the following commands to troubleshoot integrated data for ISDN interfaces:

debug dialer events—Used to display debugging information about the packets received on a dialer interface.

debug isdn q931—Used to check outgoing dial-peer matching for an ISDN incoming call. Enable this command on both sides of the call. The output indicates whether the messages are generated by the calling party router (indicated by TX ->) or by the called party router (indicated by RX <-).

debug voip ccapi inout—Used to show how a call flows through the system. From the output, you can see the call setup and teardown operations performed on both the telephony and network call legs.

show isdn active and show isdn status—Used to show the active data and voice calls.

debug ppp negotiation—displays information on the PPP traffic and exchanges, and negotiates Link Control Protocol (LCP), Authentication, and Network Control Protocol (NCP). A successful PPP negotiation first opens the LCP state, then authenticates, and finally negotiates NCP. Multilink Parameters such as Maximum Receive Reconstructed Unit (MRRU) are established during LCP negotiation.

debug ppp error—displays protocol errors and error statistics associated with PPP connection negotiation and operation.

debug ppp authentication—displays PPP authentication protocol messages, including CHAP packet exchanges and Password Authentication Protocol (PAP) exchanges.

debug voip dialpeer all—displays dialpeer selection based on the incoming digits

This document is called:

Configuring and Troubleshooting VWIC2-xCTE1-PRI Modules for Inbound ISDN Multilink PPP Data Calls

Components Used

The information in this document is based on these software and hardware versions in the lab environment

·Cisco 3845 with VWIC2-2MFT-T1/E1 and PVDM2-64 running IOS® Software Release 12.4(24)T1

·Cisco 2811 with WIC-1B-U-V2 running IOS® Software Release 12.4(7h)

My question now is: Is a PVDM2 module actually needed to support ISDN data-only calls???
