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.
