Configuring and Troubleshooting ISRs with HWIC-2CE1T1-PRI with PVDM2-24DM for incoming async calls
Now we all know that ISRs are becoming more and more popular for customer deployments. In many environments, customer need to configure an ISRs that can accept incoming calls from both Async and ISDN users. Such a setup is commonly used to provide network connectivity to users who travel and are telecommuters, and also for Small Office-Home Office (SOHO) sites.
As we all know that many customers are migrating from their old NM-xCTE1-PRI modules to HWICs and VWICs because NM-xCTE1-PRI modules are End-Of-Sale as of December 29, 2008. Pl. visit following url for EOS announcements and migration path.
https://www.cisco.com/en/US/prod/collateral/routers/ps5855/eol_c51_484362.html
That said, HWICs are the perfect replacements for old NMs for data calls. This document describes how to configure an Access Server to accept incoming Async calls on ISDN T1 PRI circuits. The configuration provides the minimum setup required for the Integrated Service Routers ( ISRs) to accept the call. You can add additional features to this configuration based on your needs.

Certain show commands are supported by the Output Interpreter Tool ( registered customers only) , which allows you to view an analysis of show command output.
Note: Before issuing debug commands, please see Important Information on Debug Commands.
· debug dialer—displays DDR debugging information about the packets received on a dialer interface. This information can help to ensure there is interesting traffic that uses the dialer interface.
· debug isdn q931—shows call setup and tear down of the ISDN network connection (Layer 3).
· debug modem—displays modem line activity on an access server. The output displays when the modem line changes state.
· debug modem csm—enables you to troubleshoot Call Switching Module (CSM) problems on routers with internal digital modems. With this command, you can trace the complete sequence of switching incoming and outgoing 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 authentication—displays PPP authentication protocol messages, including CHAP packet exchanges and Password Authentication Protocol (PAP) exchanges.
· debug ppp error—displays protocol errors and error statistics associated with PPP connection negotiation and operation.

Can we move our AS5350 RAS setup on ISR-G2 Series will it be efficient to handle , below are our existing modules on the AS chassis
AS5350-AC |
AS5350 NP108 DFC |
AS5350 E1 8 PRI DFC |
I am testing the RAS setup on PRI line with :
Cisco2911
HWIC-2CE1T1-PRI
PVDM2-36
Now incoming ISDN calls are coming through the router however getting issue on Async calls.
I am not able to get any debug output for incoming and out going calls.
Below is related conf on router
interface Group-Async1
ip unnumbered Dialer1
dialer in-band
dialer idle-timeout 300
dialer rotary-group 1
async mode interactive
no keepalive
