See the applications section, para 8.3 "Partial Insert and Multidestinational Working" on page 145 for a
discussion of this facility.
If
is selected, the dialogue continues as with the Drop Mux on the Tx path.
If
is selected the following screen is displayed:
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:
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
Baseband menu continues as with the
number of timeslots inserted must match the number of 64kbps channels selected for this destination on
the `Sat TS` screen above.
