I have a WIC-1DSU-T1 in a 3640 (IOS 12.2T). It configures fine but doesn't see the T1. I am trying to make a frac T1 (4 DSOs). I replace it with an external CSU/DSU and and use a V.35 WIC and that works. Also tried a NM-2CT1-CSU and it works too. Any suggestions to make the WIC-1DSU-T1 work? thanks

service-module t1 timeslots 1-3 speed 64
service-module t1 framing esf
service-module t1 linecode b8zs
ip address 10.1.1.1 255.255.255.0
