Quantum and Evolution Series Installation and Operating Handbook
7-27
Options:
Normal
Specifies that no attempt is made to re-acquire terrestrial Drop/Insert
frame synchronization if CRC synchronization cannot be achieved
within 8ms.
Resync if CRC lost for 8ms
Specifies that re-acquisition of the terrestrial Drop/Insert frame
synchronization should occur if CRC synchronization cannot be
achieved within 8ms.
Factory default:
Normal
Description:
This option is applicable only with G.732 Drop/Insert bearers when the
‘Process bearer CRC’
option is set to
‘Check CRC’
. It controls whether a
strict implementation of ITU G.704 is carried out, forcing re-acquisition of
the terrestrial Drop/Insert frame synchronization if CRC synchronization
cannot be achieved within 8ms.
Edit-Tx-Baseband-Advanced-Timeslots Menu
This menu contains the following options:
•
Number used
. This controls the number of timeslots dropped off the terrestrial bearer
and sent over the satellite.
•
Timeslots
. This option is used to select which timeslots are dropped.
•
Maintain ID
. This controls whether timeslot identity is maintained over satellite (i.e.
whether the timeslots represent different data streams or are all part of the same
stream).
•
Idle code
. This controls whether dropped timeslots are replaced with Idle code.
