GD-1060 CIRCUIT DESCRIPTION

5.4 NCU PWA

The NCU PWA consists of the transformer, relay, analog switch, and other peripheral devices. It controls

switching of the line path, generates dial pulses, detects line current, detects a ring signal, and monitors

the line.

The NCU PWA is connected to CN3 on the Main PWA.
