On E1 ATM circuits make sure scrambling is on, also make sure that the Framin
g you have configured on the routers is what the Telco switch is set for. You m
ay need to make sure that the IMA group index coming in from the network is dif
ferent then the one the router sends to the network. Cisco boxes need to have d
ifferent a group index.
The main thing when I have worked on E1 IMA is that the framing is the same, an
d on the 3640 it isa different default then on the 7200 series routers.
Hope this helps,

We have Cisco 7200s in the hubs and 3600s with 4 port IMAs at the
remote sites. I can loop the line on the 3600 and from the 7200 ping
the local interface....the ping travels across the pvc to the 3600 and
back. But when we normalize the circuit, we have interface up and
line protocol down. The hub router is working fine with other PVCs.
Anyone every have any problems with the 4 port IMA on an E1 circuit?
