A modem for Time Division Multiplexed Digital Subscriber Line applications eliminates the requirements for a Hybrid Balanced Network and employs low noise termination of the load resistors (32, 34) using switchable transistors (Q1, Q2) for saturation of the line driver or a switchable parallel balancing impedance (40) activated synchronously with the receive time slot (48) of the TDM protocol. |
