NOTE: Make sure that the jumper for selecting type of call is
positioned at "V" - audio/video calls .
ADAPTING THE BUS LINE
In the event that the door entry phone is the last appli-
ance connected to a branch of the BUS line, the line has
to be terminated with a VT (Video Termination) jumper to
ensure the best quality video signal (see figure alongside) .
Terminate the line and place a suitable jumper in position
'B' or 'C' and check the quality of the video signal on the
nearest monitor .
If the door entry phone is not the last appliance on the
branch, place the jumper in position 'A' (non-terminated
line) .
