Abstract
Steering logic (10) for interconnecting a transceiver (11) with a baseband bus is disclosed. The transceiver is connected to a broadband bus and transmits or receives modulated carrier wave signals. The transceiver has a data in terminal (16 or 19) and a data out terminal (18 or 35) for inputting or outputting digital signals at baseband. The transceiver also has at least one control terminal (20 or 32 and 38) and is responsive to a control signal or signals for enabling or disabling the transmitting and receiving functions of the transceiver. The steering logic (10) includes a baseband bus terminal (A) to which may be applied baseband digital transmit signals and to which the steering logic may apply digital receive signals. The logic circuitry is responsive to baseband digital transmit signals applied to the baseband bus terminal (A) for generating a control signal or signals to enable the transmitting function and disable the receiving function of the transceiver.
