For the feature to be enabled, the port to which the Adjund Feature Module is connected must be programmed as a DSS console with call announce.

SECURE OFF-HOOK VOICE ANNOUNCE

TELEPHONE CONNECTIONS This telephone system supports the Secure Off-Hook

Voice Announce (SOHVA) feature provided by certain

keyset models. Two data-paired station ports are

required to provide the SOHVA feature.

NOTE: If non-secure off-hook voice announce

capability is required, it can be provided by the model DB32S-xu console as described above.

The SOHVA equipped telephones contain a

6-position, 3-pair

line jack. Using

6-wire,

twisted-pair

cable, connect the two inside pairs of the line jack to the first data-paired port and connect the outside pair to the second data-paired port. Refer to Flgure 2-5 for

an illustration of this wiring.

Connect pins 3 and 4 to the voice pair and pins 2

and 5 to data pair of the first data-paired port.

Connect pins 1 and 6 to the voice pair of the second

data-paired port.

To enable the SOHVA feature, the following

programming considerations must be taken:

The first paired-port must be programmed as a

muttiline

The second paired-port must be programmed as a

POWER FAILURE STATION CONNECTIONS The system provides three tip and ring pairs

connected to lines

1,2,

and 3 as emergency, power

failure circuits. These power failure pairs are located

as detailed on Table 24 and Figure 24. A power failure pair is only active during a power failure. An

industry standard, single-line telephone, such as a

type 2500, can be connected to a power failure pair

and used to provide communications capability should the AC power to the system be interrupted.

A-LEAD CONTROL

DEVICE CONNECTIONS

The KSU can detect an A-lead (A and Al) control signal when it is applied to lines 7 and 8. An A-lead control device can be bridge-connected to these lines via terminal clips on the J-4 station connector block. Refer to Table 24 and Figure 24 for connection

details.

DATA DEVICE CONNECTlONS

When a serial data printer is used printout, or a video display terminal (VDT) is used to perform class of

senrice

programming connect the data device to terminal clips on the J-4 station connector block.

The distance between the device and the KSU can be up to 500 feet in a quiet electrical enviroment. Shielded cable may be required at some sites for runs. For longer distances, a limited distance modem must be used to relay the data communications between the wmmon equipment and the data device. Refer to Table 2-4 for connection details.

When preparing a cable for connection to a data device, refer to the manufacturer’s manual for the equipment being interfaced, and make thefollowing wiring connections:

Wire the KSU RD line (data from device to KSU) to

the device TD (transmit data) output pin.

Wire the KSU TD (data to device from KSU) pin to

the device RD (receive data) pin.

Wire the KSU SG (signal ground) pin to the device

COMMON AUDIBLE AND

AUXILIARY STATION INTERFACE

Two sets of relay closure available at the J-l bbcks.One set (J-l connections) provides a dry-contact closure whenever any of the TELCOIPBX

lines, connected to the KSU, ring. The other set (J-2 connections) provides a dry-contact closure whenever system station port 17 rings. These contact closures

track the ringing pattern in both cases. The contacts

are closed during the ringing period and are open during the silent period.

KEY SYSTEM/MULTIFUNCTION

(HYBRID) CONFIGURATION

The system can be configured to operate as either a key system or as a multifunction (hybrid) system.

Configuration is by way of a wire strap placed between

clip terminals 27 and 28 of station connector block J-4. The KSU is shipped from the factory as a key system’

(KF). To convert operation over to the multifunction (MF) system, add the strap.

The KF and MF designations are equipment type

catagories as stipulated in FCC rules and regulations,

Part 68, Number on the equipment label. The appropriate registration number must be reported to

company at the time of connection along with other

FCC mandated information. (Refer to Installer/user
