RGUS 125 65
10.1.3 B-channel loop
“B-channel loop” mode is required in order to run a bit error test using a loopbox at the
remote end as well as to test leased lines.
ARGUS - Single tests menu
Activate the "B-channel LOOP“
The ARGUS will wait for a call. Any incoming call
(regardless of the service) will be taken immediately.
The ARGUS will switch a loop back in the B-channel
that is specified by the exchange and then send the
recieved bit pattern back to the caller/sender.
(The “B-channel Loop” remains active. In the Main
menu, if <TM> is pressed, the ARGUS will return to “B-
channel Loop, wait active”, see page 100). From this
menu, you can start a second B-channel loop
connection (this is also possible using < TM >).
If the ARGUS takes a call, the caller's number will be
shown in the display (e.g. 235190700),
along with the B-channel used (e.g. B01) and the
number dialled (e.g. 907070).
Use the cursor keys to display additional information
(e.g. UUS…) if available.
<MENU> The ARGUS will return to the Main
menu.
