If Partial Insert is selected the following screen is displayed:
Normally, when using Drop / Insert, the m odem determines the expected data rate from the satellite from
the number of timeslots specified. However when using partial insert t he dat a rate from the satellite has to
be specific a l ly 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:
On this screen the dat a for this destinatio n is selected f rom the to tal receive da ta. The incom ing data fr om
the satell ite 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 t he 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.
