E1 bandwidth

Unanswered Question
Jul 9th, 2003

Can Router 3640-IOS 12.0(7) support E1 bandwidth? When we connect E1 bandwidth by two 2500 or 2600, they are working fine but when we connect 3640 to either 2500 or 2600, it fails.

Please help!

I have this problem too.

I upgrade IOS to 12.1(1)T suggested by the link but we still can not make it work. We found out when we connect to E1 by WIC 1T card and IOS 12.0(7) version, connection is up!
