SUBSCRIBER SEGMENT. The Subscriber Segment consists of several types/configurations of subscriber equipment, any one of which, with proper registration and status, is all that is needed by an individual subscriber to utilize the communications service. Each ISU controls unit operation, transmits/receives single channel subscriber-link data, converts the data to/from voice, receives subscriber-link signals from potential handoff antenna beam(s), chooses the best handoff options and determines its own location.
