The 3T1 plug-in card is designed for the Loop-O9550-A/C and Loop-AM3440 series and provides DS0-SNCP (64 kbps sub-network connection protection). Users can mix the non-SNCP protected traffic with SNCP protected traffic on the same T1 ring. It allows each DS0 time slot in the 3T1 interface to be interchanged and multiplexed onto a digital network.
Continuous error checking, performance polling, and in-service diagnostics are provided through the main controller of the Loop-O9550-A/C and Loop-AM3440 series. In addition, LEDs on the plug-in card itself provide status indicators.
