A. The DS3 card terminates the signal on the ports at the backplane. To check the Performance Monitoring (PM) data on a DS3 from an external device, check the PM data on the OCn that is cross-connected to the DS3 circuit. This enables you to monitor any path-level errors that come in on the DS3 signal.
