The selection is the same as the

Bearer Routing
The bearer to the Insert Mux can either be looped from the Drop Mux, or generated internally. The
following prompt is displayed:

In most situations
which the Tx data was dropped. This however forces the receive data to be passed to the terrestrial
using the terrestrial clock (which is already clocking the bearer) and hence is the `normal`
plesiochronous mode. For other clock modes, such as where it is necessary to use the satellite clock or
a station clock to drive the clock to the terrestrial equipment, use
The PCM bearer at the input to the Drop Mux is looped to the Insert Mux. If this
bearer should fail (no clock or AIS) the modem will switch temporarily to

clock source for the Backup bearer (Satellite, Internal, or Station clock).
The modem generates a suitable formatted PCM bearer internally with
multiframes (G.732 CAS) and CRC's (T1-ESF & G.732) as it is set to utilise (ie
it will not generate a terrestrial TS16 CAS multiframe unless it is operating in a
CAS mode and therefore expects one). When so configured the Rx Clocking
menu asks for the selection of the clock from which to source the Generated
bearer (Satellite, Tx Clock In, Internal, or Station clock).
Partial Insert
This option only available if the Extended D/I feature if available (standard on P300-TCM) and is
provided to simplify Multidestinational working. It allows some of the incoming Rx data to be inserted
onto the insert bearer, and the information for other destinations to be discarded. This screen is only
displayed if Rx=Tx is , when Rx=Tx is
multi-destinational) Partial Insert makes no sense, and the option is not displayed.
