Configuring and Troubleshooting E1 R2 Signaling for Data Calls

Cisco - Configuring and Troubleshooting E1 R2 Signaling for Data Calls

Introduction

This document provides a configuration example and troubleshooting techniques for E1 R2 signaling for data calls.

Prerequisites

Requirements

Before attempting this configuration, it is recommended that you read the E1 R2 Signaling Theory document. For information on E1 R2 signaling for voice applications, refer to the document E1 R2 Signaling Configuration and Troubleshooting.

Components Used

This configuration was developed and tested using the software and hardware versions below. This configuration shows a back-to-back lab setup between a Cisco 3640 router and a Cisco AS5300 access server.

  • The AS5300 is simulating the client and is running Cisco IOS® Software Version 12.2(3).

  • The 3640 is acting as a server and is running Cisco IOS Software Version 12.1(10).

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.

Conventions

For more information on document conventions, see the Cisco Technical Tips Conventions.

Background Information

E1 R2 signaling allows a Cisco universal access server to talk to central office trunks that also use E1 R2 signaling. R2 signaling is an international signaling standard that is common to channelized E1 networks. There is no single standard for R2 signaling. The ITU-T Q.400-Q.490 recommendation defines R2, but a number of countries implement R2 in entirely different ways.

Cisco Systems addresses this challenge by supporting many localized implementations of R2 signaling in its Cisco IOS software. R2 custom localization means that R2 signaling is supported for a wide range of countries and geographical regions. Cisco is continually supporting E1 R2 signaling variants in new countries.

Note: Only Modem ISDN channel aggregation (MICA) and Nextport digital modem modules support R2 functionality. No R2 support is provided for Microcom modems or non-modem applications.

Configure

In this section, you are presented with the information to configure the features described in this document. This configuration is valid for the following scenarios:

  • Modem dialin connections over E1 R2

  • E1 R2 back-to-back connections

  • E1 R2 connections between Cisco router

Note: The configuration of the E1 controller is the same for data or voice calls. The only difference is:

  • For data calls you need to configure the modems to accept the calls.

  • For voice calls you need to configure the voice ports to accept the calls.

Note: To find additional information on the commands used in this document, use the Command Lookup Tool (registered customers only) .

Network Diagram

This document uses the network setup shown in the diagram below.

Configurations

Configuring E1 R2 for data calls involves two general steps:

  • Configuring E1 R2

  • Configuring the modems and related issues

The E1 R2 configuration is based on information obtained from the Telco. Refer to the document E1 R2 Signaling Configuration and Troubleshooting for additional information on the E1 R2 specific configuration.

The modem configuration is similar to that for any access server with, for example, a PRI line.

Troubleshoot

This section provides information you can use to troubleshoot your configuration.

For more information on troubleshooting E1 R2 failures, refer to E1 R2 Signaling Configuration and Troubleshooting.

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.

  • show controllers e1 - displays the controller state that is specific to controller hardware. For details, refer to Understanding the show controllers e1 Command.

  • show diag - on the Cisco 3600, displays hardware information for the router, verifies if all hardware is recognized.

  • debug modem csm - debugs the Call Switching Module (CSM) used to connect calls on the modem.

  • debug cas - provides real-time traces of the CAS signaling bit status.

  • debug modem - displays the modem line activity on an access server.

  • show modem version - displays version information about the modem firmware, controller, and DSP code.
