ORDERING INFORMATION
GENERAL DESCRIPTION
T
he 00330 DTSS3A provides voice coupling and DTMF
decoding for a telephone, headset, and loudspeaker in a selec-
tive signaling order wire system.
The DTSS3A comes in a housing measuring 15-3/8"W x 7-7/8"D x
1-3/4"H. It can be installed in 19- or 23-inch equipment racks.
The unit features one- to six-digit station dialing and one- to three-
digit all call dialing.
Unanswered calls time out in 90 seconds or may be voluntarily
terminated by the caller. A buzzer is cycled one second on/two
seconds off for an incoming call. Ring-back tone is provided at the
same rate. The buzzer and ring-back tone may be turned off.
Outputs are available for external bells or lights to signal incom-
ing calls.
The DTSS3A works with either a two-wire or four-wire telephone.
The front of the DTSS3A includes a headset jack, speaker mute
switch, test points, test jacks, operational-indicating LEDs, and a
test/reset switch. The backplane includes a modular phone jack
and wire-wrap pins for external connections.

key system phones to order wire. Use with four-wire phones
only.
♦49922 M Lead Control Driver - Adapts M lead control in fiber
optic communications system.
♦49924 Active Auxiliary Port - Provides three-way active bridge
for repeater applicatons where the levels are not
+7 dBm RCV/-16 dBm XMT.
The terminal operates on -22 to -56 VDC input power.

2. WIRING
Wire the DTSS3A as required. Refer to Fig. 2 for a functional
schematic of the unit.
The DTSS3A uses a buzzer to announce incoming calls. A phone
with a ringer may be used with an external ringing generator
connected to the order wire terminal. (Refer to note 2, on Fig. 2.)
When using a phone with a ringer, replace the 44022-00 module
with a 44022-10 module.
The DTSS3A can be expanded to two or three phones at a single
location. To add phones, connect the bypass ports of additional
DTSS3A units to ports 2 and 4 of the bridge on the main order
wire terminal.
3. SWITCH AND STRAP SETTINGS
Refer to Tables A through F and Figs. 3 through 8 to set the
straps and switches on the modules and DTSS3A backplane.

OPERATION
T
he DTSS3A operates as a party-line communications system
with station selection and conferencing capabilities. System
activity can be monitored with the loudspeaker. Privacy is not
provided.
To place a call:
1. Determine if the system is being used by:
♦Listening to the loudspeaker, or
♦Taking the phone off hook and listening, or
♦Plugging in a headset and listening.
2. If the order wire is available, take the phone off hook and dial the
desired station using the appropriate station call number (code). To
call all stations on the system, dial the all call number. The buzzer
will sound at the called station, and you will hear the ring-back tone
(optional).
3. If the call is not answered, you can:
♦Press the * button to cancel a station call or the # button to
cancel an all call, or
♦Wait 90 seconds for the call to be cancelled automatically.
4. When the call is answered, the ring-back tone and buzzer stop operat-
ing.
5. Additional stations can be added to the conversation by dialing the
appropriate station numbers.
