Creating DS0 Groups on E1 Trunk
To create DS0 groups, logical voice port in digital trunk, just use the command
cas-ds0 group.
The numbering for the logical voice port created as a result of this command is
trunk-id:ds0-group-no
, where
trunk-id
is defined as the platform-specific
address for a particular trunk. Usually the
trunk-id
is expanded to
slot/sub-
slot/port
.
For example, ‘cas-ds0-group 1’ automatically creates the voice port 0/1/0:1
when issued in the configuration mode for module 0/1/0.
To map individual DS0s, define additional DS0 groups under the E1 trunk,
specifying different time slots. Defining additional DS0 groups also creates
individual DS0 voice ports.
