10.10.3 Time measurement: Interchannel delay
The ARGUS establishes two separate connections to a remote loopbox. The loopbox
sends the respective B-channel data back on the same channel. The ARGUS measures
the propagation delay for the data on each of the B-channels and determines the difference
between the two propagation delays (interchannel delay). The measurement (continuous
measurement) must be terminated manually.
ARGUS in the Single tests menu
Enter - or select from the speed-dialing memory - the
call number of the loopbox
Perform measurement
The ARGUS displays the average (avg), the shortest
(min) and the longest (max) interchannel delay in
msec. as well as the average interchannel delay in bits
(multiples of the time required to send a bit at 64 kBit/s)
- it takes 15.26 µsec to send a bit at 64 kBit/s).
The measurement will be repeated in cycles.
(continuous measurement)
If the measurement cannot be performed (e.g. because the call number entered was wrong
or no B-channel was free) the ARGUS will display the corresponding cause. When it is
connected to a loopbox, if the ARGUS does not receive the data back within 13 seconds, it
will display the message “No LOOP”.
