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.
