Dual-tone Multi-frequency Receiver—An optional upgrade to the system common control unit (RCTU) that provides Dual-tone Multi-Frequency (DTMF) receivers for system Direct Inward System Access (DISA) CO lines, E&M tie lines, DID, DNIS and ANI lines, Auto attendant announcement devices, remote change of call forward-external destination, DNIS external call routing, and stations and other peripherals that connect to standard telephone circuits. The RRCS comes in three models: the RRCS-4 (provides four DTMF receivers), the RRCS- 8 (eight DTMF receivers), and the RRCS-12 (12 DTMF receivers).

Optional RS-232 Serial Interface Unit—A subassembly installed on the RSIU optional interface unit that allows the system to be connected to any of the following features: voice mail SMDI, MIS for ACD, SMDR, local DK Admin/DK Backup personal computer, external maintenance modem, Open Architecture personal computer.

Optional RS-232 Serial Interface Unit—An optional PCB that provides interface to any of the following features: voice mail SMDI, MIS for ACD, SMDR, local or remote DK Admin/DK Backup Personal computer, built-in (RMDS) or external system maintenance modem, Open Architecture personal computer. By itself, the RSIU PCB provides one interface port. With up to three RSIU/RMDS subassemblies, it can provide up to four interface ports.

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 RSTU has a built-in 80V RMS sine wave ring generator. The RSTU also has connectors for the R48S, which extends station loop length and is described in this section.

Standard Telephone Interface Unit—An optional PCB functionally identical to the RSTU. RSTU2 also contains a 90-volt DC message waiting/generator/switching circuit to operate standard telephone message waiting lamps.

Wall bracket Fixture—Bracket that is part of an installation kit (RFIF) that is used to floor mount systems.

Strata AirLink Wireless System Interface Unit—A proprietary PCB that enables wireless telephone functionality to Strata DK systems.

Floor Mount Fixture—Fixture that is part of an installation kit (RFIF) that is used to floor mount systems.

Optional 48V Power Supply—Subassembly that can be connected to the RSTU or RDSU to extend the loop length of standard telephone circuits (including the resistance of the phone) from 600 ohms to 1200 ohms.

Secondary Directory Number.

Super Frame.

Single-line Telephone.

Simplified Message Desk Interface: RS-232 link from PIOU, PIOUS, RSSU, RSIS, or RSIU modular jack connected to a voice mail machine to provide Strata DK voice mail integration.

Software MIS for ACD.

Factory-installed sub-unit board that is “piggy-backed” onto the PSTU or PSTU2.

Reference interface points (“S” or “T”) of an ISDN network. S/T interfaces are

RJ-45, 8-wire connection interfaces for ISDN equipment. An NT-1 is needed to network U- type BRI lines to S/T type interfaces.

Telephone Application Programming Interface.
