Serial0 is up, line protocol is down

[ndinc]

New T-1 install through our fiber network (ethernet. Its a DS transport (basically a P2P).

AL light on WIC - Orange
CD light on WIC - Green

The 2600 say
"Serial0 is down, line protocol is down"

The 1700 (remote office)
"Serial0 is up, line protocol is down"

Is there anything I should be looking at right away?

Thanks.

service-module t1 fdl ansi" on remote but not on main office??? Does this need to be there?? Also if P2P then dont you need one side as clock source internal??

 

[ndinc]

No "service-module t1 fdl ansi" doesnt need to be there, I will remvoe it. Residual from an off the shelf router config.

Do I have a clock source statement? if so, clarify and I will remove.

I will remove and report back.

Thanks for the quick reply.

 

[ndinc]

Nothing...

Changed the encapsulation to PPP from HDLC
Reomved other garbage..

Still nothing...

Clock Source (i re read you previous post). I just might need a clock source. Whats the syntax in IOS for that?

Thanks again.

 

[JOAMON]

I think its service-module t1 clock source internal when in interface config mode but I am not in front of a router right now to confirm. Clocking wont keep the line from comming up it would just cause the timing to be off causing packet loss. Also....when you removed the previous statement from the serial interface you know you have to shut it down and wait a few seconds and then bring it back up for the new settings to take over.

 

[artesian2000]

Physical handoff on both sides is a t-1?
service-module t1 timeslots 1-24? Not sure if by default that is enabled if you are using t-1.

I got the serial side up no problem.

Clock works

No I am having a problem wiht routing...

Thanks for your help
