Enabling E1 R1 Modified Signaling allows a Cisco AS5800 universal access server to talk to central office trunks that also use R1 Modified Signaling. R1 Modified 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.
Cisco Systems supports native R1 Modified Signaling on both E1 and T1 interfaces. This version of software supports R1 Modified 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 signaling requirements.
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.
The following restrictions are for the use of R1 Modified Signaling:
This feature is supported on the Cisco AS5800 universal access server.
The following are hardware and software prerequisites to enable R1 Modified Signaling:
For information on upgrading your Cisco IOS images, modem portware, or modem code, go to the following locations:
None.
The following diagram illustrates a service provider using R1 Modified Signaling with E1 and a Cisco AS5800 access server.
This section describes how to enable R1 Modified Signaling on your Cisco AS5800 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.

The following is a sample R1 Modified Signaling configuration in Taiwan:

The following command applies to R1 Modified Signaling.
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}
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 Modified Signaling will collect ani and dnis information. |
dnis | Indicates R1 Modified Signaling will collect only dnis information. |
ani-dnis.
Controller configuration
This command first appeared in Cisco IOS Release 11.3 P.
The following example would configure R1 Modified Signaling on a Cisco AS5800 (T1 interface) and specify the collection of both ani and dnis information:
5800(config-controller)# cas-group 1 timeslots 1-24 type r1-modified ani-dnis
5800(config-controller)# ^Z
