POWER FAILURE TELEPHONES
Power Failure Cut-Through(Figure 4-5)
When system AC power fails, the 8ATRU PCB automatically
cuts through the first 2 trunk circuits to 2 Power Failure
Telephone connections.To install Power Failure Cut-Through:
1. Locate an available 8-pin jack in a trunk (A) block or station
(B) block.
Local codes may prevent you from using a DDK con-
nector on the A block for optional equipment.
2. For the 8-pin jack chosen, cross-connect the associated wire
pair from the A or B block to the cross-connect block.
3. Install a modular jack for each Power Failure Telephone
within six feet of the telephone’s location.
4. For each Power Failure Telephone, run one-pair of 24 AWG
station cable from the cross-connect block to the telephone’s
modular jack.
5. Terminate the station cable WHT/BLU - BLU/WHT leads to
the RED and GRN lugs in the modular jack.
6. Install bridging clips as required.
To test the Power Failure Telephone:
1. Connect a Power Failure Telephone per Figure 4-5.
2. Power down the system.
3. At the Power Failure Telephone, lift the handset.
You should hear dial tone on the trunk you connected
in Figure 4-5.
4. Place a test call.
If power is restored while a cut-through call is in
progress, the call is maintained until the user hangs up
the Power Failure Cut-Through telephone.

DSS CONSOLE
Installing a DSS Console(Figures 4-6 and 4-7)
The DSS Console gives a keyset user a Busy Lamp Field (BLF)
and one-button access to extensions, trunks and system features.
Keep the following in mind when installing DSS Consoles:
You can only connect 4 DSS Consoles.

You can only connect DSS Consoles to Super Display or 34-
Button Display telephones.

A DSS Console does not require a separate station port – it
connects directly to the keyset.
To install a DSS Console:
1. Turn the telephone upside down and remove the plastic filler
plug from the DSS modular connector.
2. Plug the DSS Console’s 8-pin modular line cord into the
telephone’s DSS connector.
3. Plug the other end of the 8-pin line cord into the DSS
Console’s 8-pin jack.
4. If you have a 24-Button DSS Console, attach the metal plate
to both the DSS Console and telephone as shown.
Programming DSS Consoles
1801: DSS Type
For the extension to which you have connected the DSS Console,
enter 1 for 24-button, 2 for 110-button and 0 for unassigned.1801: DSS Block Number
For the extension to which you have connected the DSS
Console, enter the number of the block that corresponds to the
connected console. A block is a unique DSS Console assign-
ment. The system provides up to 4 blocks; one for each console.
Your consoles can share the same block if you want
them to have the same programming. They will still
have unique Personal Speed Dial numbers, since a
DSS Console uses the Personal Speed Dial for the
extension to which it is attached.1704: DSS Console Key Assignment
Program the DSS Consoles keys. Refer to the software manual
for additional programming details.

2-OPX MODULE
Installing the 2-OPX Module (Figure 4-8)
The 2-OPX Module (P/N 92177A) provides two 2500 type ana-
log circuits for connection to on-premise 2500 type single line
devices (i.e., telephones, fax machines, modems, etc.) and to
telco OL13B/C OPX circuits. It uses a single digital extension
circuit for the power and signaling for both analog ports.To install a 2-OPX Module:
1. Locate an 8-pin modular connector in a trunk block or sta-
tion block.
Local codes may prevent you from using a connector
on the trunk block for optional equipment.
2. For the connector chosen, cross-connect the associated wire
pair from the trunk or station block to the cross-connect block.
3. Install a modular jack for the 2 OPX Module within six feet
of the module’s location.
4. Run one-pair 24 AWG station cable from the cross-connect
block to the modular jack.
5. Terminate the station cable WHT/BLU - BLU/WHT leads to
the RED and GRN lugs in the modular jack.
6. Install bridging clips as required.7. Ground the 2-OPX Module by connecting a 12 AWG ground
wire from the FG lug to a known earth ground.
8. Plug a line cord into the 2-OPX unit and the 2-OPX’s modu-
lar jack.
The DS1 LED on the 2-OPX Module lights steadily.
Programming 2-OPX Modules
1801: Extension Circuit Type
Assign the 2-OPX extension circuit type 21.
The 2-OPX Module uses a single port.
Notes:
Each 2-OPX Module provides 2 OPX ports. The first 2-OPX
extension number is the same as the port’s extension number.
The second 2-OPX extension number is the first port plus
201. For example, the two extension numbers for the 2-OPX
Module plugged into extension 314 are 314 and 515.

In fixed slot systems, the above is true only for a 2-OPX con-
nected to the first DSTU PCB in the system. When connected
to the second DSTU PCB in the system, the first 2-OPX
extension number is still the same as the port’s extension num-
ber, but the second 2-OPX extension number is the first port
plus217. For example, the two extension numbers for the
2-OPX Module plugged into extension 316 are 316 and 533.

WALL-MOUNT KIT
Installing the Wall-Mount Kit
You can use a wall-mount kit to attach any key telephone to a
wall. The wall-mount kit includes a mounting bracket, wall-
mount screws and a handset hanger.
Installing the Wall-Mount Handset Hanger (Figure 4-10)
1. Remove the rubber plug that covers the slots for the handset
hanger. Store the plug in a safe place.
2. Insert the handset hanger in the slot provided beneath the
telephone’s hookswitch.
