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 selectNormal (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.
