External Speaker Box—A speaker/amplifier that can be configured with the system to provide a variety of functions, such as a paging speaker and/or Background Music (BGM) speaker.

Acable used to connect an HHEU-equipped digital telephone or an HHEU-equipped electronic telephone to the external speaker box (HESB) for the Loud Ringing Bell feature.

Headset/Loud Ringing Bell Interface—Subassembly that fits inside a digital telephone or a 6500-series electronic telephone to allow a headset or an external speaker box (HESB) to be connected to the telephone.

Optional Reserve Power Battery Charger (DK14)—One or two can be connected to the power supply to maintain normal operation during a power failure.

Subassembly that fits into a 6500-series electronic telephone enabling it to receive Off-hook Call Announce (OCA) calls. The telephone must be connected to an Electronic Telephone Interface Unit (PEKU) or a Standard Telephone/Electronic Telephone Interface Unit (PESU) equipped with an Off-hook Call Announce Subassembly (EOCU) to receive OCA, and must have three-pair wiring.

Remote Maintenance Modem Subassembly—A subassembly installed on an Option Interface Unit (PIOU or PIOUS) that allows the system to be connected with a remote administration/maintenance terminal or DKi Admin/DKi Backup personal computer.

Integrated Services Digital Network.

Dual-Tone Multi-Frequency (DTMF) Receiver/ABR Tone Detector Unit—An optional PCB installed on the TMAU motherboard. The K4RCU3A must be installed to recognize Dual- Tone Multi-Frequency (DTMF) tones generated by a standard telephone (or any other device connected to a standard telephone circuit) and it is required for Direct Inward System Access (DISA) and DID. The K4RCU3A circuits are also used to detect busy tone for the Automatic Busy Redial (ABR) feature and must be installed to allow ABR to operate.

CO Line/Digital Telephone Interface Unit (DK40i)—The KCDU has two loop start CO line circuits and four digital telephone circuits. The KCDU digital telephone circuits can support all but one of the devices supported by either the PDKU or Base Unit integrated digital telephone circuits: digital telephones, PDIU-DIs/PDIU-D12s, PDIU-DSs, ADMs, DDCBs and RPCIs.

Modular add-on key or integrated circuit that installs onto the K4RCU3 to add the auto attendant feature to the DK40i.

The optional PCB provides four standard telephone circuits and it can only be installed in the base unit. The KSTU2 supports the two-wire devices such as standard telephones, Auto Attendant devices, voice mail machines, and facsimile machines. The KSTU2 can also support an alternate Background Music (BGM) source on circuit four.

Local Access and Transport Area.

Liquid Crystal Display—The optional display on digital and electronic telephones that displays calling information.

Least Cost Routing.

Long Distance Information.

Light Emitting Diode—Status indicators located on printed circuit boards (PCBs), digital telephones, and electronic telephones.
