Configuring E1 R2 Signaling

Take a Channel or Interface Out of Service

You can take a specified channel or an entire PRI interface out of service or put it into one of the other
states that is passed in to the switch.
To do so, complete one of the following tasks in interface configuration mode:
Command
AS5350(config-controller)# isdn service dsl
number b_channel number state state-value
AS5350(config-controller)# isdn service dsl
number b_channel 0 state state-value
These are the supported state values:

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.
The Cisco implementation of R2 signaling has DNIS support turned on by default. If you enable the ANI
Note
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, the ANI
number is assigned to gateway A. Also, note that ANI is similar to caller ID.
