INTERCEPTOR 147 2 Mbit/s and Data Analyzer
MON
Monitor. Derives the 2M Reference from a resistor-
isolated source. This selection provides a 75
Ω
input
impedance for the 2M Ref Input signal.
BRIDGE
Derives the 2M Reference from a source not equipped
with resistor-isolated monitor points. This selection
provides greater than 1000
Ω
input impedance for the
2M Ref Input signal.
TERM
Termination. Derives the 2M Reference from a
source on the network where cable equalization is
required. This selection provides a 75
Ω
input
impedance for the 2M Ref Input signal.
3.3.8 TS Idle
Use the TS Idle item to specify the pattern used in
unselected timeslots.
The format of the TS Idle item is:
TS Idle bbbbbbbb
where bbbbbbbb is an 8-bit byte that you can specify.
To specify each bit (represented by a “b”), move the cursor
to the bit you want to change and press SELECT to change
a “1” to a “0” or a “0” to a “1.”
NOTE: When Channel is set to RESTRICTED, the format
of TS Idle is:
TS Idle bbbbbbbX
where X is the rightmost bit, which cannot be
changed. When the byte is inserted into unselected
timeslots, the rightmost bit is always “1.”
Therefore, only the seven leftmost bits of the TS
Idle byte can be specified.
