E1 R2 Signaling
R2 is an international signaling standard for channelized E1 networks used in Europe, Asia, and
South America, equivalent to channelized T1 signaling in North America. There are two elements to R2
signaling:

T1 CAS Signaling
Channel-associated signaling (CAS) occurs in-band within the data channel, rather than on a separate
signaling channel as is the case (on the D channel) with ISDN PRI. For T1 CAS, specify parameters such
as frame type and line code.

Configure Dial Peers

Your next step in preparing to set up dial peers is to determine the configurable options that you want to
enable.
Configurable Options
Configurable options are the attributes to be applied to calls handled using that dial peer. These typically
