hi
actually i have two sites connected with analog E&M in trunk mode
with routers 3845(vic2-2E&M) and 1760 (vic-2E&M) and with these routers
it works ok, but i need to change the router 1760 and install a 2811 (vic2-2E&M)
but with the new router doesn`t work the connection, the status of the E&M is
connected in both sites, here is the config that iam using in both routers
and a debug vpm all of one of them, i can see that in the debug shows something
like an "error input" but i dont know what is the problem
some help please
thanks
