Configuring E1 R2 Signaling
R2 signaling is an international signaling standard that is common to channelized E1 networks. You can
configure a channelized E1 interface to support different types of R2 signaling, used in older analog
telephone networks.
Note
The Cisco implementation of R2 signaling has dialed number identification support (DNIS) turned on
by default. If you enable the automatic number identification (ANI) option, the collection of DNIS
information is still performed. Specifying the ANI option does not disable DNIS collection. DNIS is the
number being called. ANI is the caller’s number. For example, if you are configuring gateway A to call
gateway B, then the DNIS number is assigned to gateway B, and the ANI number is assigned to gateway
A. Also, note that ANI is similar to caller ID.
Configure
To configure E1 R2 signaling, use the following commands, beginning in global configuration mode:
Command
Purpose
Step 1
AS5350>
enable
Password:
password
AS5350#
Enters enable mode (also called privileged EXEC
mode) and enters the password. You are in enable
mode when the prompt changes to
AS5350#
or
AS5400#
.
Step 2
AS5350#
configure terminal
Enter configuration commands, one per line.
End with CNTL/Z.
AS5350(config)#
Enters global configuration mode. You are in
global configuration mode when the prompt
changes to
AS5350(config)#
or
AS5400(config)#
.
Step 3
AS5350(config)#
controller e1 0/0
AS5350(config-controller)#
Enters controller configuration mode to configure
your E1 controller port.
Specifies E1 feature card slot, port number, and
channel. On the E1 feature card, port number
values range from 0 to 1.
Step 4
AS5350(config-controller)#
ds0-group 1
timeslots 1-30 type r2-analog r2-compelled
ani
Configures the time slots that belong to each E1
circuit for R2 signaling. Sets R2 signaling to R2
ITU Q411, the tone signal to R2 compelled
register signaling, and ANI to address information
provisioned option.
R2 line signaling options include
r2-analog
,
r2-digital
, and
r2-pulse
.
Tone signaling options include
dtmf
(default),
r2-compelled
,
r2-non-compelled
, and
r2-semi-compelled
.
You can also set
ani
(ANI address information
provisioned) for any of the above options.
Step 5
AS5350(config-controller-cas)#
cas-custom 1
Enters the channel number to customize.
