QCDU2

Standard/Electronic Telephone Interface Unit—An optional PCB that provides the system with a combination of two standard and four electronic telephone circuits. The standard telephone circuits can support standard telephones and optional hardware peripherals, such as voice mail devices and fax machines. Except for the electronic DSS console, the PESU electronic telephone circuits can support the same stations and peripherals that the PEKU does. The PESU is also used with older Strata systems.

Phantom Directory Number.

Option Interface Unit—An optional PCB that provides support and/or circuit interface for optional hardware peripherals and upgrades.

The same as the PIOU, with some exceptions; most notably, the PIOUS has one external paging interface zone, while the PIOU has four.

A term used to identify a station circuit or CO line circuit location.

Battery cable that connects reserve power batteries to cabinet RPSU280 power supplies (102 cabinet installations).

A Toshiba-supplied adapter—An adapter that is used to connect: an SMDR device, ASCII maintenance terminal, or remote maintenance external modem.

A Toshiba-supplied adapter—An adapter that is used to connect: the modular SMDR, SMDI, MIS for ACD, Open Architecture (OA), maintenance ports of the PIOU, PIOUS, RSSU, RSIU, or RSIS to the DB-9 (PPTC-9) connector of a call accounting machine, DK Admin, DK Backup personal computer (PC), SMIS personal computer or Open Architecture personal computer.

Designed to connect directly to the DB9 connector of PC COM ports, while PPTC connects directly to an ASCII terminal female DB25, not a PC COM port male DB25.

Used to connect a Call Center Viewer PC or SMIS PC to the RS-232 Strata DK424 MIS port on the PIOU, PIOUS, RSIU, or RSSU.

Primary Rate Interface.

Standard Telephone Interface Unit—An optional PCB (an older version of RSTU2) with a built-in ring generator that provides interface for eight standard telephones or optional hardware peripherals (voice mail devices, Background Music source, fax machines, etc.). The PSTU2 has a square wave ring generator that can be set for 190V peak-to-peak or 130V peak-to-peak. The PSTU2 is also used with older Strata systems.

Public Switched Telephone Network.

CO Line Digital Telephone Interface Unit (DK14)—Provides one CO line (loop start) circuit and two digital telephone circuits on each PCB. The QCDU2 interfaces with digital telephones, PDIU-DIs/PDIU-DI2s/RPCI-DI, ADMs connected to the telephones and PDIU-DSs, but does not support a DDSS or DDCB console.
