Configuring T1-CAS Analog Emulation (H.323)
Identify the port number and then enter the configuration information provided by
Step 1
your telco, as in the following example:
c4224(config)# controller T1 1/port#
c4224(config-controller)# framing esf
c4224(config-controller)# clock source internal
c4224(config-controller)# linecode b8zs
Assign time slots to the DS-0 group and identify the emulation type.
Step 2
You can define each DS-0 group to use FXS, FXO, or E&M, using the following
command:
c4224(config-controller)# dso-group group groupnumber
timeslots timeslotnumber type emulationtype

For example, the following command configures the first DS-0 group with one
time slot using FXS emulation in loop-start mode:
c4224(config-controller)# dso-group 0 timeslots 1 type fxs-loop-start
