Phone Line Test Points
You can attach a telephone test set to
the D9112 at the TELTEST points
located above the TELCO jack on the
lower left corner of the panel. See
Figure 7.
Communication Failure
After 10 attempts to reach the
receiver, the panel goes into
communication failure. The
panel clears any reports in its
phone buffer. SERVC COMM
FAIL appears in the display at
command centers.
If you use the D128 Dual Phone Line
Switcher, the D9112 makes 10 attempts on each line before going into communication
failure.
Pressing Command 4 silences the tone. When communication restores (a report is
acknowledged by the receiver), the display clears automatically. See
Phone Parameters
in the
D9112 Program Entry Guide
(74-06145-000) for reporting options
.
Ground Start
Some telephone systems require a momentary ground input to initiate dial tone. To
interface with a ground start system, insert a plug-in relay (D136) into socket K6/J5 and
set the ground start jumper in the GND START position. Terminal 10 must be connected
to an earth ground reference.
Relay Installation
Power down the D9112 before inserting the D136 relay into socket K6/J5. The relay
socket is in the lower left corner as shown in Figure 8. The plug-in relay is shorter than
the socket it plugs into. You can install it in either the left or right end of the socket.
Don’t rely on relay labeling:
You shouldn’t rely on the labelling to install D136
relays. Check for the side with three pins. The three pins go on the top
side.
Incorrect insertion does not damage the
relay or the D9112, however the
related circuits do not function
properly. A ground start relay must
not be inserted when dialing loop
start.
