Router serial interface burstable to 3.0M

We have our Internet connection set up as a burstable 0-3M frame-relay link.

The serial interface is a standard WIC-1T. The bandwidth on the interface is showing the default of 1544Kbit.

I have been seeing a lot of FECN flags on the connection.

Monitoring shows this link is using well beyond the 1.5M most of the time.

I know the BW parameter on the interface is not a setting for the inteface, but is this a problem with this interface as far as, am I not getting the full benefit of the 0-3 M bandwidth?

or will the WIC1T utilize as much bandwith as the provider gives us?

Re: Router serial interface burstable to 3.0M

Hi Richard, the circuit provider should be able to provide you how much bandwith currently the circuit is using, you are probably going over 2 megs,I personally have not worked with WIC-1T but rather the ones with integrated csu/dsu's T1 cards, but as I read the WIC-1T maximun sync speed is 2.048 Mbps , you probably would want to look into other options such as bonding two T1s MLPPP to get full 3 megs benefit.
