If Partial Insert is selected the following screen is displayed:

Total data rate for ALL dest' from satellite: [1152000] ??????? (YES)

Change, Rx, Baseband, Insert Mux, Partial, Total Rate Menu

Normally, when using Drop / Insert, the modem determines the expected data rate from the satellite from the number of timeslots specified. However when using partial insert the data rate from the satellite has to be specifically set (as there is more data coming from the satellite than will be inserted). It must be N x 64kbps, N=2 to 32 (minimum of 2 not 1, as you cannot have a multidestinational carrier with only 1 x 64kbps incoming ! ). The screen is then displayed:

Sat TS: 1-3, 10-12

Toggle:??-?? (YES)

Change, Rx, Baseband, Insert Mux, Partial, Data Select Menu

On this screen the data for this destination is selected from the total receive data. The incoming data from the satellite is labelled as timeslots 1 - N. NOTE this labelling bears NO RELATION to the terrestrial timeslots from which the data was dropped at the Tx site. It should be read as First through Nth 64 kbps channel of the total sent. For example in a 256kbps incoming carrier the Rx data is referred to as TS 1 - TS 4 (first, second, third and fourth 64kbps channel in the 256kbps) whether it was originally dropped from timeslots 1, 2, 3, & 4, or timeslots 13, 17, 19 & 23. At the receive site (whether partial insert is active or not)

there is no concept of `Dropped timeslots`, there is only first 64kbps, second 64kbps etc.

When he selection of data for this destination is complete, the Insert Mux option on the Change, Rx, Baseband menu continues as with the Drop Mux option on the Change, Tx, Baseband menu. The total number of timeslots inserted must match the number of 64kbps channels selected for this destination on the `Sat TS` screen above.
