Toshiba DK8 Door PHONE/LOCK Control Unit and Door Phone Installation, Ddss Programming Overview

NOTE:

1.DDSS console cable runs must not have the following:

•Cable splits (single or double)

•Cable bridges (of any length)

•High resistance or faulty cable splices

2.See Section 100-816-208for secondary protection information.

CAUTION!

When installing the DDSS cable, do not run parallel to and within 3 feet of an AC power line. AC power lines should be crossed at right (90°) angles only. In par- ticular, avoid running station wire pairs near devices that generate electrical noise, such as neon or fluorescent light fixtures.

5.12DDSS Console Configuration. The follow- ing considerations should be made when installing DDSS consoles:

• DDSS consoles can connect only to Circuit 8 of the Base Unit digital telephone circuit set or Circuit 8 of the PDKU.

• A maximum of two DDSS consoles can be installed per system equipped with an Expan- sion Unit.

• DDSS consoles can operate with an attendant electronic telephone, as well as with a digital one.

• A KCDU will not support a DDSS.

5.13DDSS Programming Overview

Program 03

•Code 64 identifies the slots that support DDSS

consoles.

Program 28

•Assigns DDSS console(s) to telephones.

Program 29

•Assigns button functions for DDSS consoles.

5.20HDSS Console Connections

5.21The HDSS console must be connected to the data pairs of circuits 7 and 8 on a PEKU in the Expansion Unit (via the MDF) with standard two- pair twisted, jacketed telephone cable. To accom- modate the connection, the instrument end of the

SECTION 100-816-206

MARCH 1993

HDSS console cable should be terminated in a modular station connector block (RJ-11). Refer to Wiring Diagrams, Section 100-816-208, for wiring/ interconnecting details. The overall length of the cable run from the Expansion Unit (KSU) to the HDSS console must not exceed 500 feet (152 meters), if using 24 AWG cable. The HDSS con- sole can operate with either an electronic or digital telephone (preferably an LCD model).

CAUTION!

When installing the HDSS console cable, do not run parallel to and within 3 feet of an AC power line. AC power lines should be crossed at right (90°) angles only. Avoid running HDSS console wire pairs near devices that generate electrical noise, such as neon or fluorescent light fixtures.

5.22HDSS Console Configuration. The follow- ing considerations should be made when installing an HDSS console:

• A PEKU PCB is required in the expansion unit for an HDSS console. (The DSS switch on the PEKU must be set to DSS.)

• Two PEKU ports are required for the HDSS console (always Circuits 7 and 8).

• The PESU does not support the HDSS console.

• A system must be configured with the Expan- sion Unit to support an HDSS console. Only one HDSS console can be installed in a system.

5.23HDSS Programming Overview

Program 03

•Codes 23 and 24 identify the slot that supports

a PEKU that interfaces with the HDSS console.

Program 28

•Assigns HDSS console to a telephone.

Program 29

•Assigns individual button functions for the HDSS console.
