Dear all
i have a central point and a brach office, these two points connected via E1 .
th ebandwidth between these two point was 64K , now i have increased two 256K via timeslot.
right now my serial line protocol is down
here sho interface 2/0:5

Hello,
Please confirm with telco that they provisioned 256K via timeslots 22-25.
Sometime they say "yes, done" then turns out something was't done.
Failing that have them come on site and prove the circuit is working.
Hope this helps, please rate post if it does!

acctullay they ar sure that telco has done its job.
do u have any idea about the configuration?

If telco has said timeslots 22-25, you have configured correctly and the router has no fault.
Now as I was saying before, I have experienced many many times that in talking, telco was sure, then when faced with evidence, had to admit the job wasn't done right. Do not accept the circuit upgrade and do not pay for it until it is proved working.

Hi,
As it is evident from the output, youe serial link is up but the line protocol is down, it strongly indicates towards an access circuit issue.
There can be two reasons:
1. There is a config mismatch (of timeslots) in Telco's device, and your device.
2. The Telco has not actually comissioned the link.

My point exactly, and I got rated a '2' for saying that :(
Nevermind.
