Features

The TN553 packet data line circuit pack has 12 ports that can connect through a cross-connect field to a TN726B circuit pack and provides software-administrable connections between the Switch Processing Element (SPE) and system access ports. Inside the system, the TN553 connects to the packet bus and converts mode-2 protocol to mode-3 protocol which connects the TN726B circuit pack to the TDM bus for asynchronous EIA connections to adjuncts.
