C/DTR Originate Call Control
This call control method applies equally to the SBUQHS/QHB and
SBUQLS/QLB.
C/DTR control is based on V.24/V.35 circuit 108/1, or in X.21 control line
‘C’. This provides the facility of setting up a call without exchanging
messages. The number to be dialled is stored in the Quad User Modules
by using the command menus.
The interface circuits used are as follows:-
V.24/V.35
