Hi
What's difference between:
controller e1 0/0/0
ds0-group 0 timeslots 1-15,17-31 type r2-digital r2-compelled ani
and
controller e1 0/0/0
cas-group 0 timeslots 1-15,17-31 type r2-digital r2-compelled ani
Thanks
Solved! Go to Solution.

Here's info from cisco doc:
!--- From Cisco IOS Software Release 12.0(5)T and later,
!--- the command cas-group is renamed ds0-group

Hi Peterson,
Hope all is well :)
The first one listed;
controller e1 0/0/0
ds0-group 0 timeslots 1-15,17-31 type r2-digital r2-compelled ani
is a "standard E1"
And the second one listed;
controller e1 0/0/0
cas-group 0 timeslots 1-15,17-31 type r2-digital r2-compelled ani
is a "CAS - T1"
CAS is the transmission of signaling information within the voice channel. Various types of CAS signaling are available in the T1 world. The most common forms of CAS signaling are loop-start, ground-start, and E&M. The biggest disadvantage of CAS signaling is its use of user bandwidth to perform signaling functions. CAS signaling is often referred to as robbed-bit-signaling because user bandwidth is being "robbed" by the network for other purposes. In addition to receiving and placing calls, CAS signaling also processes the receipt of DNIS and ANI information, which is used to support authentication and other functions.

Hi Rob.
So, in second case I'm using a controller E1 with 23 channels, correct?
