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 Main Menu
The speed-dialling memory opens (see
page 364).
Use the cursor keys to scroll to desired
the number or enter a new number.
Perform measurement
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 interchannel delay
min: shortest interchannel delay
max: longest interchannel delay
bit:
The average interchannel delay in
bits (multiples of the time required
to send a bit at 64 kbit/s, it takes
15.26 µsto send a bit).
Stop measurement.The ARGUS will
display the last measurement.
