Can TCCS work with no VAD between two 2620 routers with 1.54 M of bandwidth

I currently have two 2620 Routers with TCCS workng between them. There are 46 compressed voice channels and 2 Clear channels. When i have VAD on the cross connects it works. The problem is VAD is too aggressive and calls that toll bypassed through this link get aggressive VAD cutoffs etc.

I tried bringing up the TCCS with NO VAD , one HDV t1 comes up 23 channels, +Clear channel,

The other t1 gets about 4 channels up and it dies, the processor goes up to about 95% CPU utilization.

Can the 2620 handle this??

The IOS is 12.2.10B

If the CPU slams up it may be more than simple utilization. Issue a show proc cpu and see what is eating resources. Compare memory utilization as well. Could be a bug in a process, and you will want to do a bug scrub to ensure it isnt a known issue. Make sure your bandwidth isn't an issue as well.
