Configuring E1 R2 Signaling
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, which is used in
older analog telephone networks. Note that this feature is only available for MICA modems.
Note
the 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 router A to call router B, then the DNIS number is assigned to
router B, the ANI number is assigned to router A. Also, note that ANI is similar to Caller ID.

Purpose
Enter enable mode (also called
privileged EXEC mode).
Enter the password.
You have entered enable mode when the
prompt changes to
.

Enter global configuration mode. You
have entered global configuration mode
when the prompt changes to
5300(config)#.
Enter controller configuration mode to
configure your E1 controller port. The
E1 controller ports are labeled 0 to 3 on
the Quad cards and 0 to 7 on the Octal
cards.
Configure the timeslots 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 the ANI addr info
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 addr info
provisioned) for any of the above
options.
Enter the channel number to customize.
