Wireline Interface Board
The Wireline Interface Module serves as the interface between the customer telephone lines and the station. In gener¬al, The Wireline Interface Module processes and routes all wireline audio signals between the station and the landline equipment (such as consoles, modems, etc.). Landline-to-station and station-to-landline audio signals are connected to the Wireline Interface Module via the 50-pin Telco connector (J17) or the orange connector (J61) on the station Backplane.
