I have a customer with a 2851, running H.323 and three T1 PRIs and a T1-CAS. They need to monitor all in-use B-channels and all DS0s on the T1-CAS. Every time I look for a way to do that, all the links point to E1s on an AS5300. Has anyone gotten this to work with a T1 PRI on an ISR? And if so, how? Jonathan
