When transparent TS16 options are selected and the P300/Quantum/Evolution are in
drop and insert mode, the modems must be set to maintain timeslot identities if TS16 is
part of the drop and insert group.
Edit-Unit-Advanced-Special Modes Spoof Screen
This option allows full connectivity of a PCM bearer to be `spoofed` even if the link is
connected over satellite via a `thin route` (i.e. less than the full PCM bearer using Drop &
Insert). If enabled the following features of the PCM system appear transparent end–to-
end:
1. AIS (all ones)
2. Backward Alarm
3. CAS Backward alarm (G.732 only)
Note that when enabled, AIS is forced over the whole PCM bearer and so this option
should not be used with cascaded Drop & Insert, where AIS from the second modem in a
cascade would cause the inserted data from the first in the cascade to be lost.
