8.1.3.3 Time measurements on leased lines
B-channel delay
The ARGUS places a call 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 the B-channel from the keypad (first press
<DEL>) or use the cursor keys to set the B-channel.
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).
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”.
