This function makes it possible for the operator to define (or
redefine) the IDB parameter RBS TF Compensation Value.
Display TF Compensation Value
The IDB parameter RBS TF Compensation Value (in ns) is
displayed.
Display spare bits, display spare bits in timeslot 0 on G.703,
values (0 or 1) for bits Sa4-Sa8.
Define spare bits (bits can be defined independently of each other).
Display CRC-4 (Cyclic Redundancy Check /G.704/), display
whether handling of CRC-4 in timeslot 0 on G.703 is on or off.
Switch on CRC-4.
Switch off CRC-4.
Monitor maintenance data, display PCM reference data and update
changes continuously.
Modify PCM Receiver Sensitivity
Sets the individual PCM Receiver Sensitivity values for an E1
transmission interface. The values are defined and referred as
parameters PCM-A-REC-SENS and PCM-B-REC-SENS in the
IDB.
Exception: A DXU which uses the PRACT transmission circuit
does not support the PCM Receiver Sensitivity values.
Display PCM Receiver Sensitivity
Displays the individual PCM Receiver Sensitivity values for an
E1 transmission interface. The values are defined and referred as
parameters PCM-A-REC-SENS and PCM-B-REC-SENS in the
IDB.
Exception: A DXU which uses the PRACT transmission circuit
does not support the PCM Receiver Sensitivity values.
Modify LBO values for transmission interface.
Sets the individual LBO values for a T1 transmission interface.
The values are defined and referred as parameters LBO-A and
LBO-B in the IDB.
Exception: A DXU which uses the PRACT transmission circuit
does not support the LBO values.
Display LBO values for transmission interface.
Displays the individual LBO values for a T1 transmission
interface. The values are defined and stored as parameters LBO-A
and LBO-B in the IDB.
