Chapter 5 Configuring the Voice Interfaces
To configure T1-CAS E&M emulation with MGCP using Cisco CallManager
Administrator, perform the following steps and configure the route pattern and
dial plan:
Identify the port number and then enter the configuration information provided by
Step 1
your local carrier, as in the following example:
Gateway(config)# controller T1 1/port#
Gateway(config-controller)# framing esf
Gateway(config-controller)# clock source internal
Gateway(config-controller)# linecode b8zs
Step 2 Assign time slots to the DS-0 group and identify the emulation type.
You can define each DS-0 group to use FXS, FXO, or E&M, using the following
command:
Gateway(config-controller)# ds0-group group groupnumber timeslots
<timeslotnumber> type emulationtype
Replace emulationtype with e&m-wink-start or e&m-delay-dial.
Replace groupnumber with the DS-0 group number and replace timeslotnumber
with the number of DS-0 time slots to allocate to the group. For example, the
following command configures the first DS-0 group with one time slot using FXS
emulation in loop-start mode:
Gateway(config-controller)# ds0-group 0 timeslots 1 type
fxs-loop-start
You can configure DS-0 hunt groups by assigning a range of time slots to a DS-0
group and then configuring multiple voice peers with the same destination pattern
pointing to multiple voice ports.
For example, the following command assigns 12 time slots to DS-0 group 1:
Gateway(config-controller)# ds0-group 1 timeslots 1-12 type
fxs-loop-start
