Configuring Cisco MC3810 Series Concentrators to Use High-Performance Compression Modules

ds0-group

Cisco IOS Release 12.1(2)T

Examples

The following example configures DS0 groups 0 and 1 with different CAS signaling on controller T1 0:

router(config)#

controller T1 0

router(config-controller)#

mode cas

router(config-controller)#

framing esf

router(config-controller)#

linecode b8zs

router(config-controller)#

ds0-group 0 timeslot 1-10 type fxs-ground-start

router(config-controller)#

ds0-group 1 timeslot 11-24 type fxo-loop-start

The following example configures DS0 groups 1 and 2 on controller T1 0 to support transparent CCS:

router(config)#

controller T1 0

router(config-controller)#

mode ccs cross-connect

router(config-controller)#

ds0-group 1 timeslot 1-10 type ext-sig-master

router(config-controller)#

ds0-group 2 timeslot 11-24 type ext-sig-slave

Command Description

codec complexity

Matches the DSP complexity packaging to the codec(s) to be supported.
Voice channels in DS0 groups must be in the idle state before codec
complexity can be changed.

mode ccs

Configures the T1/E1 controller to support CCS cross-connect or CCS
frame-forwarding.
