TTL Pin as input
FIG. 35 TTL PIN AS INPUT
If you use a TTL Pin as Input, you can program two different functions sepa-
rately when edges change:
• Positive edge: The event is activated when the voltage on the TTL Pin
changes from 0V to +3.3V.
• Negative edge: The event is activated when the voltage on the TTL Pin
changes from +3.3V to 0V.
The following functions can be configured (Function Code):
– - : No function, the Pin is not used.
– Call Out/Accept Call In/Drop: Via this function you can establish a
connection to a certain Phone Number, accept an incoming call or drop
a call. Under POTS Line/ISDN Line you select the line (1, 2, 3, 4, 5 or
6) on which the connection is established. Under Audio Line you select
the Audio line that is activated when the call is accepted.
– Call Out (Level Trig.): Same function as above, however, except that
here the level is analysed and not the edge (level triggered).
– Drop: If you activate this function, a connection on the selected line (1,
2, 3, 4, 5 or 6) can be dropped.
– Set Audio Line: This function allows you to switch a caller to a prede-
fined Audio Line. Under POTS Line/ISDN Line you must indicated
which caller line you want to use (1, 2, 3, 4, 5 or 6).
– Lock Audio Line (Level Trig.): With this function you can lock an Au-
dio Line. Under POTS Line/ISDN Line you must indicated which
caller line (1, 2, 3, 4, 5 or 6) is locked for the Audio line. This function
is level triggered.
– Load Preset: Via this function it is possible to load a preset which you
have to select under Preset.
