Code
Description of Arguments
Command or Query.
Sets or returns Rx Clock Source in the form x, where:
0=Rx Satellite
1=Tx-Terrestrial
2=Internal(SCT)
3=INSERT (command valid only when Rx framing is Insert or D&I++ and interface is G.703 or set for D&I loop)
EXAMPLE: <0/RCK=1 (selects Tx-Terrestrial)
Command or Query.
Sets or returns Invert Receive Clock, in the form x, where:
0=Normal
1=Inverted
Command or Query.
Sets or returns Eb/No alarm point in the form xx.x, where:
xx.x=Value, in dB, from 0.1 to 16
Resolution=0.1 dB
EXAMPLE: <0/EBA=12.3
Command or Query.
Sets or returns Rx Buffer Size in the form xxxxx, where:
xxxxx=Value, in 2-byte steps (unless other limitations apply), from 00016 to 32768 bytes
(See Chapter 6, Sect. 6.2.1.5.2)
EXAMPLE: <0/RBS=08192 (selects 8192 bytes)
Command or Query. (Audio/IDR parameters)
Sets or returns Rx Audio Volume control in the form aabb, where:
aa=Rx 1 volume control value, in dB: Valid values are -6, -4, -2, +0, +2, +4, +6, +8;
bb=Rx 2 volume control value, in dB: Valid values are -6, -4, -2, +0, +2, +4, +6, +8.
EXAMPLE: <0/RVL=-2+4 (sets Rx 1 to -2 dB and Rx 2 to +4 dB)
Command or Query. (INSERT mode parameter)
Sets or returns Receive Terrestrial Alarm Enable conditions in the form x, where:
0=Disables the alarm
1=Enables the alarm.
EXAMPLE: <0/RTE=0 (disables the alarm).
