cas-group (controller e1)

To configure an E1 controller on a Cisco AS5200 with channel associated signaling (also known as robbed bit signaling), use the cas-group controller configuration command. Use the no form of this command to disable channel associated signaling for one or more timeslots.

no cas-group channel timeslots range type signal

channel	Single channel group number, in the range 0 to 30.
timeslots range	One or more ranges of timeslot values, in the range 1 to 31. You can specify timeslot ranges (for example, 1-31), individual timeslots separated by commas (for example 1, 3, 5), or a combination of the two (for example 1-3, 8, 17-31). The 16th timeslot is not specified in the command line, because it is reserved for transmitting the channel signaling.
type signal	Specifies the type of channel associated signaling. Choose one of the following signal types to configure: · e&m-fgb--Specifies ear and mouth channel signaling with feature group b support. · e&m-fgd--Specifies ear and mouth channel signaling with feature group d support. · fxs-loopstart-- Specifies foreign exchange system loopstart signaling support. · fxs-groundstart--Specifies foreign exchange system ground start signaling support. · sas-loopstart--Specifies specific access station loopstart signaling support. · sas-groundstart--Specifies specific access station ground start signaling support.
