ARGUS
A
RGUS 125 85
10.10.2 Time measurement: B-channel delay
The ARGUS places a call to itself (self call) or to a remote loopbox and measures the
propagation delay for the data in the selected B-channel. 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 for the outgoing call.
Enter the B-channel on the keypad.
Perform measurement
The ARGUS displays the average (avg), the shortest
(min) and the longest (max) B-channel delay as well as
the average B-channel delay in bits (in multiples of the
time required to send a bit at 64 kBit/s).
(The time for sending 1 bit at 64 kBit/s = approx. 15.26
µs.)
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”.
