T1_ESF & T1_ESF_S: 1544kbps Extended Super Frame (_S Special)
The P300 Modems do not require the _S `Special` mode to support N=9 and N=18,
as the P300 Modem
equipped with the Extended D/I feature (standard on P300-TCM)
can support any value of N.
Simply
configure as follows:
1.
Select
Change, Tx, Service, IBS/SMS
2.
Select
Change, Tx, Baseband, Drop Mux, T1-ESF
.
3.
Select the number of timeslots to drop
4. Select
Leave
or
Replace
with Idle code as required.
5.
When "T1-RBS Over Satellite, 1=Normal (or no RBS) 2=Maintain RBS" is asked, select as appropriate.
If
RBS
is selected the dialogue ends here.
6.
For
No RBS,
if the number of timeslots chosen is not an `Odd values of N` (eg N=7 or 9), then the unit
will prompt "TS Identity will be maintained by TS32 multiframe (YES)" and the setup is complete.
7.
If you have selected an `Odd value of N` the unit will prompt "TS Identity over satellite, 1=Normal
(maintain), 2=Don't maintain". If you select
Normal (maintain)
the unit will provide TS identity
maintenance
for any value of N
by using a CAS multiframe. If you select
Don't Maintain
then the
Modem will not use a CAS multiframe, and will be compatible with the same number of timeslots
selected.
8.
Configure the receive path similarly, if
Rx=Tx
is active, then only the timeslots need selecting.

Simply
configure as for T1_ESF & T1_ESF_S as above, but select T1-D4 not T1-ESF in step 2
