Monitoring an ATM Network

This section describes the network monitoring functions of the OC3port Plus.
The OC3port Plus has four receive filters that can be used to monitor the input
OC3 signal for ATM cells. The information in the first part of this section shows

statistical measurements provided by the OC3port Plus.
Using the receive filters, you can monitor "live" ATM traffic as it is being
