Strata AirLink Installation Guide 5/00
The four primary access transceivers (U7, U13, U25, and U35) use the E1 (31 B + D) interface to
each Base Station. Not all of the 32 time slots of the E1 (32 B + D) frame are used. The format is
called 8 B + D and organized as follows:
♦
Time slot N0 – synchronization time slot
♦
Time slots N1~N8 – voice channels time slots
♦
Time slots N9~N15 – idle (free) time slots
♦
Time slot N16 – signaling CCS time slot
♦
Time slot N17 – multiframe 320 ms synchronization pulse time slot
♦
Time slots N18~N31 – idle (free) time slots
