CV-1548.U.jpg

The CV-1548/G converted 2-wire telephone circuits to 4-wire circuits for transmission over multiplex systems. A straight-through patch was provided in the 4-wire mode. It also provided three signaling options. It converted a 20 Hz ringing signal to 1600 Hz, and 1600 Hz to 20 Hz for two-way ringing. It converted a dc closure to 1600 Hz, and 1600 Hz to a dc closure for originate and terminate plug supervision on one-way ringdown trunks. It also provided the option of no ringing signal conversion. The CV-1548/G is used with the TD-352/U, TD-353/U, and TD-660/U multiplexers.
