Hi all,
i just installed two vwic E1 cards on each of my cisco 2811. however i get a line protocol on and off problem.
this happens twice every minute on both sides of the E1 connections..
i thought it was a clocking thing.. made one serial interface to use internal clock..the other to use line.. same problem..
tried a loop of each of the routers and i was getting the same thing..
is there a trick to get these twins talking to each other over E1?
some one advised me that it might be an IOS problem…
