Configuring and Troubleshooting an Integrated Service Routers ( ISRs) with PRIs for Incoming Multilink Async and ISDN Calls

Contents

Introduction

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 and ISDN 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.

Prerequisites

Requirements

There are no specific requirements for this document.

Components Used

The information in this document is based on these software and hardware versions:

·       Cisco ISR router 3845 with HWIC-2CE1T1-PRI and PVDM2-24DM digital modem module.

·       One T1 PRI.

·       A PC that runs Microsoft Windows. This PC has an analog modem and a phone connection to the Public Switch Telephone Network. The PC dials the T1 PRI that is connected to the ISR 3845.

·       Cisco 1800 or 2800 ISR series routers with ISDN BRI circuits. These routers are the ISDN mlppp dialin clients. You can apply this client configuration to any router with a BRI interface. Client side configuration is not the intended purpose of this document.

·       Local Authentication, Authorization and Accounting (AAA). If you have a AAA Radius or Tacacs+ Server, you can use either of them to provide AAA for the incoming calls. Refer to Implementing the Server-Based AAA Subsystem for more information.

Note: The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Configure

In this section, you are presented with the information to configure the features described in this document.

Verify

This section provides information you can use to confirm your configuration is working properly.

Certain show commands are supported by the Output Interpreter Tool ( registered customers only) , which allows you to view an analysis of show command output.

·       Show network-clocks -- The network clock source must be derived from an external source, for example, PSTN, or PBX. To display the current configured and active network clock sources, use the show network-clocks command

·       show isdn status—ensures that the router communicates properly with the ISDN switch. In the output, ensure that Layer 1 Status is ACTIVE, and that the Layer 2 Status state = MULTIPLE_FRAME_ESTABLISHED appears. This command also displays the number of active calls.

·       show ppp multilink—displays information on active multilink bundles. Use this command to verify the multilink connection.

·       show dialer [interface type number]—displays general diagnostic information for interfaces configured for DDR. If the dialer comes up properly, the Dialer state is data link layer up message must appear. If physical layer up appears, the implication is that line protocol came up, but the Network Control Protocol (NCP) did not. The source and destination addresses of the packet that initiated the dialing are shown in the Dial reason line. This show command also displays the configuration of the timer, and the time before the connection times out.

·       show caller user username detail—shows parameters for the particular user, for example, the IP address assigned, PPP and PPP bundle parameters. If your version of the Cisco IOS software does not support this command, use the show user command.

·       show dialer map—displays configured dynamic and static dialer maps. You can use this command to check whether a dynamic dialer map is created. You cannot route packets without a dialer map.

Troubleshooting Commands

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.
