Response to Query
Rx Buffer Size RBS= 6 bytes Command or Query.
Rx Buffer Size (in milliseconds), where:
s=Defines which interface slot ( 1 or 2 )
c=Defines which channel ( 1 to 2 )
xx.x=Rx Buffer Size,
E3 mode = 0.5 to 61.0 ms, in 0.5 ms steps
T3 mode = 0.5 to 44.0 ms, in 0.5 ms steps
STS1 mode = 0.5 to 40.0 ms, in 0.5 ms steps
HSSI interface = 5.0 to 32.0 ms, in 0.1 ms steps
OC-3 interface = 2.0 to 26.0 ms, in 0.1 ms steps
GBEI interface = N/A
Example: RBS=1130.0 (selects 30.0 ms on interface 1, channel 1) RBS=
