Timeslot Re-Ordering
Selected timeslots may be independently re-ordered
on both Tx and Rx paths.
Multi-Destinational
Working
All or only a subset of the received data may be
inserted into the terrestrial bearer on the receive path
for multi-Destinational working.
Timeslot ID Maintenance
The IBS/SMS or Closed Net Plus ESC is extended to
maintain the identity of individual timeslots for all
values of N from 1 to 31.
Signalling
Both Channel Associated Signalling (CAS) and
Robbed Bit Signalling (RBS) are fully supported.
For G.732 Drop/Insert, CAS signalling is extracted
from terrestrial TS16 and carried over the satellite in
IBS/SMS TS16 and TS48 before re-inserting into the
distant terrestrial TS16.
For RBS, the IBS or Closed Net Plus ESC overheads
maintain the identity of the in-band signalling and it is
re-inserted into the terrestrial multi-frame in the correct
positions to maintain the RBS.
