摘要:
An apparatus and methods for a wireless telecommunication system to provide a wireless interface. A plurality of modems is used for processing wireless communications with a plurality of subscriber line circuits, each for providing a telecommunication connection. A control processor assigns a modem for each communication, selects one of the line circuits and associates that line circuit with the assigned modem for that communication. Thus, any of the line circuits can be used to communicate via any of the modems.

Voiceband compression techniques are employed in order to enable an RF telecommunications base station to accommodate data signals of high speed voiceband modems and FAX machines. An Ultra-High Speed Codec supports voiceband modem and FAX transmissions up to 14.4 kb/s and operates using four 16-phase RF slots. Because these codecs transmit information over several RF slots which can be contiguous, the slots within RF communication channels are dynamically allocated. The Dynamic Time slot/Bandwidth Allocation feature detects and monitors the data transmission and forms a data channel from the necessary number of slots.
