t-1 controller/interface config 3745

[jerry.mcrae]

we had a private PPP T-1 installed. one end of the circuit is a ds3 that is allocated out as seperate PPP T-1 on a 7204 b/c we have a VOIP phone system with many small branch offices. it looks like i have the ds3 controller and the serial interface configured correctly other than the fact the line protocol is down on the serial interface. on the other side we have a 3745. i have a t1 controller in slot 1 of the 3745 up - but i cant configure the interface.(config)#int s1/0

Can you post the output of "show ip interfaces brief" and "show controllers" for the T1?

What is in your config refering to the T1 controller?

Hi

Can you try this config and check whether you are getting interface serial 1/0:0 up ?

controller T1 1/0

no shut

framing esf

linecoding b8zs

clock source line

channel-group 0 timeslots 24 speed 64

Once you get the serial interface up in your config you can configure up the same using normal ip addres under it..

interface serial 1/0:0

ip address 10.x.y.z 255.255.255.0

regds

[jerry.mcrae]

(config-controller)#channel-group 0 timeslots 24 speed 64

%Timeslot 24 already used by other ds0-group

sh run ---->controller T1 1/0

shutdown

framing esf

linecode b8zs

ds0-group 1 timeslots 1-24 type e&m-wink-start

i cant get rid of the ds0-group cmd - thats why the interface is shut down. it says it still in use but its not.

Hi Jerry,

So what happens when you do the following:

conf t

controller t1 1/0

no ds0-group 1

Jerry,

You should be able to remove the ds0-group command after shutting down the controller.

conf t

controller t1 1/0

shut

no ds0-group 1

Pls. rate all helpful posts.

i tried to shut the interface and this is what i get.

(config-controller)#no ds0-group 1

Voice port(s) still in service

%This CAS group is not down, can not be changed

[jerry.mcrae]

i had to disable the voice port that the ds0-group 1 command created then i could shut the controller and remove the ds0-group then add the proper channel-group command to the controller.
