Toshiba DK8, DK 16 manual Electronic Telephone Interface Unit Peku

Circuits 1 ~ 8 on a PDKU2; the circuit must be dedicated to the PDIU-DS.

7.15PDIU-DI/PDIU-DI2 Configuration. Refer to Station Apparatus Installation, Section 100-816- 206, and Peripherals Installation, Chapter 7, for installation procedures for the PDIU-DI/PDIU-DI2. PDIU-DIs/PDIU-DI2s can be equipped with any digital telephone connected to PDKU Circuits 1 ~ 7 with PDKU1 or Circuits 1 ~ 8 with PDKU2.

7.16DDCB Configuration. Refer to Peripherals Installation, Section 100-816-207, for installation procedures for the DDCB. The DDCB must be connected to the Circuit 8 on the PDKU.

7.17ADM Configuration. Refer to Section 100- 816-206, Paragraph 7.00.

7.20PDKU Installation Procedure

7.21Install the PDKU in accordance with the fol- lowing steps:

1)Remove the PCB from its protective packag- ing.

2)Insert the PDKU into the appropriate slot (see Paragraph 5.22, and apply firm, even pres- sure to ensure proper mating of connectors.

NOTE:

Ensure the PDKU's component side is facing right when installing it in the KSU.

4)After installing the PDKU, gently pull the PCB outward. If the connectors are properly mated, a slight resistance will be felt.

7.30PDKU Wiring

7.31Refer to PDKU Wiring Diagrams, Chapter 8, for wiring/interconnecting details.

7.40PDKU Programming Overview

7.41The following parameters may be specified, through programming, for the PDKU:

Program 03

• Specify code 61 if no options are installed on a PDKU.

• Specify code 62 to indicate a PDKU that will support stations that must receive Off-hook Call Announce (OCA).

• Specify code 64 to indicate a PDKU configured

8ELECTRONIC TELEPHONE INTERFACE UNIT (PEKU)

8.00General

8.01The Electronic Telephone Interface Unit (PEKU) provides eight ports for electronic tele- phones and it must be installed in the Expansion Unit. It is recommended that the current 6500- series be used, because this series consumes the least amount of power.

8.02The PEKU can be configured to receive Off- hook Call Announce (OCA) by installing an Off- hook Call Announce Unit (EOCU). It can also be configured to support an HDSS console and an external Background Music (BGM) source connec- tor. An external amplifier for two-CO line confer- ence calls can also be connected to Circuits 6 and 7 of the PEKU. The HDSS console, the external amplifier, and the BGM source, are wired directly to the PEKU and require no additional hardware, but do require specific ports/circuits. Electronic tele- phones also wire directly to the PEKU, and they can be connected to any PEKU circuit.

8.03PEKU controls and interface connectors are shown in Figure 5-13 and described in Table 5-B.
