ARGUS 152
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 Main Menu
The speed-dialling memory opens (see
page 364).
Use the cursor keys to scroll to desired
the number or reenter the number on the

Perform measurement
Display
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 is free) the ARGUS will display the corresponding cause. If the ARGUS
does not receive the data back in the B channel within 13 seconds, it will display the
message “No loop”.
avg: average B channel delay
min: shortest B channel delay
max: longest B channel delay
bit:
The average B channel delay in bits
(multiples of the time required to send a
bit at 64 kbit/s, it takes 15.26 µs to send
a bit).
Stop measurement, the ARGUS will
display the last measurement.
