We use the Real Time Monitoring Tool (RTMT) to monitor our E1 Circuits (CM 4). We find that RTMT only gives a "used channels" figure for the ENTIRE router, as opposed to a figure for each E1 Circuit.

As an example, suppose we have four 30 channel E1 circuits on a router. RTMT gives us a utilization figure out of 120, instead of giving us four circuit utilization figures, each out of 30.

Is there a way within the RTMT to monitor channel usage on individual E1 circuits? If not, is there another tool (Either free or commercially available) that allows us to monitor individual E1 channel usage?
