Following either of these selections, the Modem counts how many timeslots are being accessed and
determines how to maintain the Timeslot identity. Refer to the section on "Timeslot Identity Maintenance"
in Appendix F on page 197. Wherever possible the Modem resolves the issues itself, but where there might
be a compatibility issue between different modem vendors the modem prompts the operator for input.
If operating with a G.732 bearer and CAS is selected, then the timeslot identity will be maintained
by the satellite CAS Multiframe used to convey the CAS signalling. No user input is required
If operating with a T1-D4 or T1-ESF bearer and RBS is selected, then the modem will maintain the
Timeslot (and RBS) identity using the normal TS32 Multiframe if possible, and if not it will activate
a satellite CAS multiframe to support the RBS. No user input is required
If no signalling (CAS or RBS) are active, then the Modem will maintain the timeslot identity by using
the satellite TS32 multiframe where possible (unless N, the number of dropped/inserted timeslots
falls into the category of `Odd values of N`). It will indicate as follows to which the operator just
answers YES to accept the information:
Change, Tx/Rx, Baseband, Drop/Insert, Ident Menu
If no signalling (CAS or RBS) is active and the value of `N` of dropped and inserted timeslots falls
into the category of `Odd values of N`, then it is not possible to maintain the timeslot identity using
the satellite TS32 multiframe. The `Odd values of N` are
N = 7, 9, 11, 13, 14, 17, 18, 19, 21, 22, 23, 25, 26, 27, 28, 29, 31
If this is the case and the Extended D/I feature is available (standard P300-TCM) then the modem
prompts to see if timeslot ID maintenance is required:
Change, Tx/Rx, Baseband, Drop/Insert, Maint' Menu
NORMAL
(MAINTAIN)
DON'T CARE
This is the end of the Drop/Insert dialogue when in Closed Net Plus ESC, IBS or CUSTOM IBS modes
P300H
TS identity will be maintained over
satellite by TS32 Multiframe (YES)
TS identity over satellite: [?]
1=Normal (maintain) 2=Don't care
The Modem will activate the satellite CAS multiframe in order to provide timeslot
ID maintenance for the `Odd value of N` selected. Note that this mode may not
be compatible with other manufacturers IBS/SMS equipment, as this is a special
feature of the P300 and P400 series modems (which is why it asks you the
question, instead of just getting on with it !).
Timeslot ID will not be maintained and the Modem will be compatible with other
manufacturers equipment for these `Odd values of N`.
