Test Results
INTERCEPTOR 147 2 Mbit/s and Data Analyzer
Active Timeslots
The Active Timeslots result provides a graphical
representation of timeslots 0 through 31 in the
following format:
F123•••789012••5
M78••••••56••901
where:
0 - 9 Indicates the last digit of the timeslot
number (0 to 31) of an active timeslot.
(A timeslot is considered to be active
when a PCM signal with a level greater
than -35 dBm is detected on the
timeslot.)
F When FAS is present, an “F” replaces
the “0” of Timeslot 0 to indicate the
presence of the FAS word.
M When MFAS is present, an “M”
replaces the “6” of Timeslot 16 to
indicate the presence of the MFAS
word.
• Replaces a timeslot’s number in the
graphical representation to indicate
that the timeslot is idle.
Rx Byte
The Rx Byte (Received Byte) result indicates the
8-bit byte received in the selected timeslot.
ABCD
The ABCD result indicates the ABCD, or channel-
associated signaling (CAS), bits in the selected
timeslot. (The ABCD result is available only when
Framing is set to MFAS or MFAS-CRC.)
