Slow Point to Point T1 Access Please Help

Hello,

We have a point to point T1 line going between our main office and a branch, and the connection is very slow, I pasted the configurations below of both routers. At the branch location we have 15 workstations accessing the database over the T1 line, at our corp. office. The database is by advantage (sybase now) and I believe it utilizes mostly UDP for connections, it's a dos application that is installed locally on each system and then connects to the database in the corporate server. We have another 4 branches that have the same configs but most of them have 10 workstations. I'm new to cisco and the guy who configured the routers is not here anymore can you please take a look and make any suggestions on how to make it work faster. Also under available bandwidth it doesn't show the full 1.5 it shows 1.1 I believe is that normal? I appreciate any help, thanks a lot in advance! ###########Simi Valley Config#################

Can you clear the counters of the serial ports of both routers wait 30 minutes and copy another sh int serial for both?

Corp2's T1 is dirty as hell. Telco problem.

Just cleared the counters, will repot the stats in 30 min. Thanks for the reply!

Thank you for the reply, do you think it coud be wic card itself? or how can we tell that it's telco's problem, because this line is brand new and when they installed it they tested it and it was fine. Thanks

I also took a look at the 2nd router that connects 3 other branches, 1 serial didn't have any errors or aborts, but the other 2 had a lot of them, is it the WIC cards going bad or a line problem?

Was the "show interface" snapshots taken when people were actually trying to access the database? -- it's utilization is near zero. Also, it would help to know the topology.

It would appear from the configurations you sent that there is more than one corporate router. If this is true, how is the database server configured to send traffic back to "simi." At first glance, I'm guessing there might be some ICMP redirects happening -- but you need to provide a complete "picture" of your network. (you might want to remove the password and community strings as well before posting)

What's the Round trip delay of the circuit when you ping from the routers to the IP on the serial port of the remote end?
