R1 Modified Signaling for the Cisco AS5200 and AS5300 Access Servers

Feature Summary

Enabling R1 Modified Signaling allows a Cisco AS5200 or Cisco AS5300 universal access server to talk to central office trunks that also use R1 Modified Signaling. R1 Signaling is an international signaling standard that is common to channelized T1/E1 networks; however, Cisco only has made this feature available in Taiwan. You can configure a channelized T1/E1 interface to support different types of R1 Modified Signaling, which is used in older analog telephone networks.

Note This type of signaling is not the same as ITU R1 signaling; it is R1 signaling modified for Taiwan specifically.

Note In the future, R1 Modified Signaling will be supported by the Cisco AS5800 access server, and will be available in Turkey as well as Taiwan.

Benefits

Cisco now supports native R1 signaling on both E1 and T1 interfaces. This version of software supports R1 signaling customized for Taiwan only. This feature allows enterprises and service providers to fully interoperate with the installed Taiwanese telecommunications standards, providing interoperability in addition to the vast array of Cisco's IOS troubleshooting and diagnostic capability. This will provide customers with a seamless, single-box, solution for their Taiwan signalling requirements.

List of Terms

line signaling---States of call setup on the Trunk A/B/C/D signaling bits.

R1 Trunk---A type of trunk to carry telephony traffic.

register signaling---Multi-frequency tone signaling in the voice channel.

Restrictions

The following are restrictions to the use of R1 Modified Signaling:

Because different line signaling uses different A/B/C/D bit definitions to represent the line state, users need to know the configuration of the T1/E1 trunk before configuring the cas-group. If the wrong type of provision is configured, the access server might interpret the wrong A/B/C/D bit definitions and behave strangely.
Cisco access servers with Microcom modems cannot support this feature.

Platforms

This feature is supported on the Cisco AS5200 and Cisco AS5300 universal access servers.

Note This feature will also be supported by the Cisco AS5800 universal access server in the future.

Prerequisites

The following are hardware and software prerequisites to enable R1 Modified Signaling:

Cisco AS5200 or Cisco AS5300 access server (without a Microcom modem)
Cisco IOS Release 11.3(3)T or later
MICA feature module

Cisco AS5200 access server. The network topology would be the same for T1 and/or a
Cisco AS5300 access server.

Configuration Tasks

This section describes how to enable R1 Modified Signaling on your Cisco AS5200 or Cisco AS5300 access server.

Table 1 describes how to configure this feature on a T1 interface, and Table 2 describes how to configure this feature on an E1 interface.

Note In both tables, the sample prompts and output are for the Cisco AS5300, but the commands and the output would be the same on the Cisco AS5200.

Command Reference

The following command applies to R1 Modified Signaling.

cas-group

To configure R1 channel-associated signaling, use the cas-group controller configuration command. Use the no form of this command to disable channel associated signaling for one or more timeslots.

cas-group channel timeslots range type r1-modified {ani-dnis | dnis}
no cas-group channel timeslots range type r1-modified {ani-dnis | dnis}

Syntax Description

channel	Specifies a single channel group number. Replace the channel variable with a number between 0 and 30.
range	Specifies a timeslot range, which can be from 1 to 24 for T1, and from 1 to 31 for E1. You can specify a timeslot range (for example, 1-31), individual timeslots separated by commas (for example 1, 3, 5), or a combination of the two (for example 1-7, 8, 17-31). The 16th time slot is reserved for out-of-band signaling.
ani-dnis	Indicates R1 Signaling will collect ani and dnis information.
dnis	Indicates R1 Signaling will collect only dnis information.

Default

ani-dnis.

Command Mode

Controller configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 11.3 P.

Examples

The following example would configure R1 Signaling on a Cisco AS5200 (T1 interface) and specify the collection of both ani and dnis information:

5200(config-controller)# cas-group 1 timeslots 1-24 type r1-modified ani-dnis

Related Commands

debug modem csm

Debug Command

The following debug command applies to R1 Modified Signaling.

debug modem

If you are having trouble, use the debug modem command to enable the modem management Call Switching Module (CSM) debug mode:

debug modem csm [slot/port]

Syntax Description

slot	(Optional) Specifies the slot number you want to debug.
port	(Optional) Specifies the port number you want to debug.

Default

All slots and ports will be debugged.

Command Mode

EXEC mode

Usage Guidelines

This command first appeared in Cisco IOS Release 11.3.

Sample Output

The following is the output of debug modem csm for an incoming call:

5300# debug modem csm
