CAUTION
Install or remove modules from the shelf only when the power is off.
If you install a module in the shelf with the power on, the internal
circuitry may suffer damage and the product warranty will be void.
Remove and install circuit boards only in a static-safe environment
(use antistatic wrist straps, smocks, footwear, etc.).
Keep circuit boards in their antistatic bags when they are not in use.
Do not ship or store circuit boards near strong electrostatic, electromag-
netic, magnetic, or radioactive fields.
For more complete information on electrostatic discharge safety
precautions, refer to BellcoreTM Technical Reference #TR-NWT-000870.

GENERAL DESCRIPTION
T
he Dantel 00331 DTSS3ON Order Wire/PABX Interface
(00331 Interface) lets any station in an order wire system
dial an access line directly to a central office or through a PABX.
The 00331 Interface can then dial out through the Public
Switched Telephone Network (PSTN). Alternately, an outside
party can dial into the order wire system and selectively dial any
desired station.
The DTSS3ON can be added to any existing order wire system
using the DTSS3A Selective Signaling Order Wire terminals.
The off-net package does not have to be at the same place as a
station package. The modules provide complete level coordinat-
ing circuits, including switchable pads on the Term Set front
panel.
Three versions of the DTSS3ON are available:
♦The B15-00331-00 unit is equipped with a term set for inter-
facing two-wire lines. It will work with either ground-start or
loop-start systems, with or without wink off.
♦The B15-00331-01 unit does not have the term set, and is
used only for interfacing four-wire E and M trunks. Both the
-00 and the -01 options feature 3-digit dialing.
♦The A15-00331-05 unit is equipped for interfacing two-wire
lines just as the -00 option; however, offers 6-digit station
address decoding.
Since the DTSS3A system does not utilize automatic privacy, the
off-net package provides a tone which announces that an off-net
caller has connected to the system.

00331-0398<90-00044> PAGE 3
The off-net package provides forced disconnect, which allows order
wire users to disconnect an unwanted call from the outside by
dialing # or * and three digits. If the unwanted caller tries to
call again, the DTSS3ON will not answer. Normal operation is
restored by pressing the # or * key again.
The 00331 Interface has three 400-type plug-in modules. The
modules include:
♦The 44443 Term Set
♦The 44023 PABX/Trunk Interface
♦The 44020 DTMF Decoder (with 49018 subassembly for
3-digit dialing or 49028 subassembly for 6-digit dialing).
The modules install into a 41071 mounting, which places the
three modules horizontally in 1 3/4 inches of rack space.
The 00331 Interface operates on -21 to -56 VDC power.
NOTE: The modules used in the DTSS3ON are registered under part
68, FCC rules. The Federal Communications Commission
requires certain precautions and procedures be followed when
connecting the DTSS3ON to the Public Switched Telephone
Network. Refer to the 44023 and 44443 module practices for
details and for the device registration numbers.

OPERATION
This Off-Net package allows any station in the order wire system to access a Telco central office or PABX line. The
Telco central office or PABX line accesses the touch-tone into the
public-switched telephone network. Conversely, an outside party
can call into the order wire network and selectively dial any
station desired.
To call out from any terminal on the order wire system:
1. Pick up the handset and press #.
2. Dial the outside access code and listen for dial tone.
3. Dial the desired outside number.
4. To terminate the call, press #.
To call into the order wire system from the outside:
1. Access the seven digit number for the outside Telco line associated
with the off-net. The caller hears one ring, followed by a short tone
burst.
2. Dial the desired order wire station code. The caller will hear a ring-
back tone until the party answers.
In a loop trunk, the person at the answering order wire station
must dial a * or # or the call terminates in 10 to 80 seconds.
Terminate the call by hanging up or dialing # (or * if the call
was answered by dialing #).
NOTE: When using two-wire lines under loop control with no wink, the
person at the called order wire station must dial a * within
10 to 80 seconds (adjustable) or an automatic disconnect
occurs. (The * overrides the disconnect.) To terminate the call,
dial #. These are factory options and may be reversed if
desired. Refer to the 49018 practice for strapping options.
Neither step is necessary when using loop control with wink or
ground start trunks.
ALIGNMENT PROCEDURE
The 00331 DTSS3ON Order Wire system comes from the factory
with all switch, strap, and level settings set. If the levels re-
quired are different than the standard level settings, use the
procedure described in Table C.
The equipment neccessary is a transmission test set capable of
serving as a:
♦Signal Generator sending a 1kHz, 600 ohn signal at various
levels
♦600 ohm level Meter (with and without 600 ohm termina-
tion).

ACTION
Refer to Fig. 1. NOTE: If using a PABX 4-wire
trunk, start at step 2d.
Calibrate the two-wire RCV level.
Set tone generator to 1kHz and connect a
600 ohm terminated meter across the generator
terminals.
Remove the meter. Using a bantam-sized phone
plug, connect the tone generator to the 2-WIRE
DROP front panel jack of the 44443 Term Set.
Plug 600 ohm terminated meter into the 4-WIRE
XMT front panel jack of the 44443 module.
NOTE: If using a PABX 2-wire trunk, skip steps
2d and 2e.
Set the tone generator for 1kHz and connect a
600 ohm terminated meter across the generator
terminals.
Remove the meter. Connect the tone generator
to the TRANSMIT DROP jack of the 44023
module.
Press the TEST/RST switch on the 44023 front
panel.
Connect the meter to the TRANSMIT LINE test
points on the 44023 module front panel.
Disconnect transmit receive level.
Calibrate the transmit receive level.
The TEST/RST switch on the front panel of the
44023 should not be changed.
Set the tone generator output for existing system
level and 1kHz. Connect it to the RECEIVE
LINE test points on the 44023 front panel.
Move meter to the RECEIVE DROP front panel
jack on the 44023 and terminate in 600 ohms.
NOTE: If testing an A15-00331-01, go to step 4.
Move meter to the 2-WIRE DROP jack on the
front panel of the 44443 module.
Test complete. Remove all test equipment and
reconnect the external equipment. Press the
TEST/RST button on the 44023.
RESULT
The functional schematic shows the normal
systems levels used in the alignment.
Set the generator output level for -4dBm.
Meter shows XMT level. Set the level for
-16dBm by using the front panel XMT pad
switches on the 44443 module.
Set the generator output level for -16dBm.
Off-hook LED comes on.
Set the level for existing system
requirements.
Off-hook LED is on. press TEST/RST switch
on the 44023 if it is not.
Meter shows DROP RECEIVE level. Adjust
receive pot for +7dBm.
Meter shows transmit level to CO line. Set
level for -6dBm using the 4-wire RCV front
panel pads on the 44443 module.
All LEDs should go out.
