ds0-group

Release 12.0(7)XK

On the Cisco MC3810, the slot number is the controller number. Although only one voice port is

created for each group, applicable calls are routed to any channel in the group.

On the Cisco MC3810 when conﬁgured for transparent CCS, the channel type conﬁgured as the

ext-sig-master is considered the master side of the permanent virtual circuit (PVC) connection

which is responsible for establishing the PVC connection. After the master channel is conﬁgured, a

ﬁxed timer of 30 seconds starts. The voice-signaling driver then generates an off-hook signal on the

master voice channel after the timer expires. The call is treated as a regular call, and the master

channel does not hang up after the connection is made. If the call does not go through, or if theT1/E1

trunk is down,the 30-second timer on the master channel side restarts. A new off-hooksignal is then

generated at the master channel side after the timer expires.

Examples

The following example conﬁgures ranges of T1 controller timeslots for FXS ground-start and FXO

loop-start signaling on a Cisco 2600 or 3600 Series router:

router(config)# controller T1 1/0

router(config-controller)# framing esf

router(config-controller)# linecode b8zs

router(config-controller)# ds0-group 1 timeslot 1-10 type fxs-ground-start

router(config-controller)# ds0-group 2 timeslot 11-24 type fxo-loop-start

The following example conﬁgures DS0 groups 1 and 2 on controller T1 1 on the Cisco MC3810 to

support transparent CCS:

router(config)# controller T1 1

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
