10.10 Time measurements
The ARGUS measures three different times:
- Connection set up time
- Propagation time of the data (B-channel delay)
- Transit time differential (interchannel delay) of the data in two B-channels.
Time measurements on a BRI or U-Interface access are only possible in TE mode.
10.10.1 Connection set up time
The ARGUS places an outgoing call and measures the time between sending the SETUP
and receiving the ALERT or CONN. The ARGUS disconnects automatically as soon as the
measurement is completed.
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 will display the connection setup time in
seconds and the received L3 messages (end of
connection setup). If the ARGUS cannot perform the
measurement (e.g. because the call number entered
was wrong or no B-channel was free) the
corresponding cause will be displayed.
