Toshiba DK 16 manual Maximum of two Qcdu PCBs may be installed in the Strata DK8

INSTALLATION-CONFIGURATION

SECTION 100-816-203

MARCH 1993

NOTE:

A maximum of two QCDU PCBs may be installed in the STRATA DK8.

3.22The STRATA DK16 Base Key Service Unit and the PDKU PCB each provide eight digital telephone circuits. The KCDU PCB provides four.

NOTE:

A maximum of two KCDU PCBs may be installed in the STRATA DK16. If a KCDU is installed, no other type of station PCB can be installed in the STRATA DK16.

3.23The following devices can be connected to digital telephone circuits:

• Digital Telephones (2000- and 1000-series):Each digital telephone requires one circuit, and each digital telephone circuit can support a digital telephone.

• Stand-alone Data Interface Units (PDIU-DS): Each PDIU-DS requires one circuit. Any digital telephone circuit, except for Circuit 8 on a PDKU1 (STRATA DK16), can support a PDIU-DS (see Note 1).

NOTES:

1.There are two versions of the PDKU: PDKU1 and PDKU2. The versions are identical, except that Circuits 1 ~ 8 on the PDKU2 can each support PDIU-DSs/ PDIU-DI, while only Circuits 1 ~ 7 on a PDKU1 can support PDIU-DSs or PDIU- DIs. Also, PDIU1 does not support 2000- series digital telephone continuous DTMF tones.

2.The Integrated Data Interface Unit (PDIU- DI/PDIU-DI2) and the Add-on Module (ADM) do not require a dedicated circuit. They share a circuit with the telephone.

3.Only one option (PDIU-DI2 or ADM) can be installed on a 2000-series digital tele- phone.

•Digital Direct Station Selection Console (DDSS): (available with STRATA DK16 only) Each DDSS Console requires one circuit. DDSS Consoles can connect only to Circuit 8 in the Base Key Service Unit and Circuit 8 on a PDKU.

The KCDU cannot support a DDSS console.

•Digital Door Phone/Lock Control Box (DDCB): Each DDCB requires one circuit. DDCBs can only connect to Circuits 3 and 4 (Ports 02 and 03) in the STRATA DK8 Key Service Unit or Circuit 5 (Port 04) in the STRATA DK16 Base Key Service Unit, and Circuit 1 (Port

12)on either the PDKU or KCDU (STRATA DK16).

3.30Electronic Telephone Circuit Connec- tions (STRATA DK16 Only)

3.31There are no electronic telephone circuits in the Base Key Service Unit, and none can be added to it. However, either the PEKU PCB, which has eight electronic telephone circuits, or the PESU, which has four electronic telephone cir- cuits, can be installed in the Expansion Key Ser- vice Unit. The following devices can be connected to electronic telephone circuits.

• Electronic Telephones (6500-,6000-,3000-,2000-series): An electronic telephone can be connected to any electronic telephone circuit. One electronic telephone circuit is required per electronic telephone.

• Electronic Direct Station Selection Console (HDSS): The system will support only one HDSS console. The console must be connected to both Circuits 7 and 8 on the PEKU. The PESU will not support an HDSS Console.

• Alternate Background Music Source: The system will support an alternate Background Music source which can be heard over digital and electronic telephone speakers and external page speakers. This source can be connected to either Circuit 3 on a PEKU, Circuit 8 on a PESU, or Circuit 4 on a KSTU or PSTU PCB.

• Conference Amplifier:An amplifier for two CO line conferencing can be connected to Circuits 6 and 7 (Ports 17 and 18) on a PEKU or PESU.

3.40Standard Telephone Circuit Options

3.41In addition to supporting standard telephones, each of the standard telephone circuits can sup- port any one of a number of single-wire-pair de- vices, including voice mail/Auto Attendant devices and modems. The QSTU, which can be installed in the STRATA DK8 Key Service Unit, has two
