6.MFI-S KTU (Dual-Tone Multip Frequency Interface Key Telephone Unit) provides circuits to serve up to 3 CO/PBX lines, and contains circuitry for CO/PBX ring detection, hold and control functions. It also sends DTMF dial signalling to CO/PBX lines in accordance with dialing from keysets. A MFI-S KTY and a DCI-S KTU can be mixed in a system.

. 7. KSI-S KTU (Keyset Interface Key Telephone Unit) provides data control to the Electronic Key Telephone

set (ET-6-l). Each KSI-S KTU provides circuits to serve up to 8 Electronic Key Telephone Sets.

8.SWM-S KTU (Switch Matrix Key Telephone Unit)

contains a 8 x 12 semi-conductor switching matrix for connection of keysets to CO/PBX lines, intercom paths, door phones, and paging trunks. Each SWM-S con- nects 8 keysets to 3 CO/PBX fines, 2 door phones, 2

intercom paths and internal and external paging trunks. Each SWM-S provides a talk battery supply for up to 8 ET-6- 1 Telephones.

9.ET-6- 1 Telephone is a fully-modular push button dial

electronic key telephone set with 35 nonlocking buttons, a 2 digit LED display and a speaker and micro- phone for voice page and handsfree answerback on ICM calls. 6 of the buttons are CO/PBX line buttons,

13 buttons are function buttons, and 16 buttons are used both for DSS (Direct Station Selection) and Station Speed Dialing. Each keyset requires 2 pair cabl- ing to the Main Distribution Frame (MDF).

10.AHR-S KTU (Automatic Hold Release Key Telephone Unit) serves up to 6 CO/PBX lines. This option provides for restoration of a held line to idle status when the outside party abandons the call. A timed disconnect signal must be sent from the central office or PBX to activate this feature. One AHR-S KTU can be installed in the ES-6- 1 KSU for this feature.

11 PBS-S KTU (External Paging/Busy Lamp Field/ Security Key Telephone Unit) provides circuitry for three optional features. It contains a l-watt amplifier and a control circuit for single-zone external paging. For applications where a l-watt amplifier is insuffi- cient, a locally provided high power amplifier may be used in addition to the PBS-S KTU. The Busy Lamp Field circuitry to detect a signal from an external source which activates an audible alarm in idle key- sets and a visual alarm in the display of all keysets. Two security circuits are provided for this purpose.

When any combination of these features is required in the system, one PBS-S KTU must be installed in the

ES-6-l KSU.

12.DPH-S KTU (Door Phone Key Telephone Unit) contains amplifiers and voice switching circuits to

provide a 2-way communication to keysets in the sys- tern. It can also be used as a monitor phone in areas where monitoring of audible activity is desired. This

KTU can serve up to 2 door/monitor phones and can provide a tone to signal assigned keysets programmed to ring when the door phone is activated.

13.DP-6-l Door Phone is a speaker unit with a speaker, microphone, and a control button to provide two-way

communication to any keyset in the system. With the DPH-S KTU installed in the KSU up to two door

phones can be connected at the Main Distribution Frame (MDF). One pair cabling is required for each door phone.

14DB -6 - 1 BLF is a modular Electronic Busy Lamp Field withe 21 LEDS. 16 LEDS show station status, 1 LED each shows paging status (both internal and external), Night Transfer, and BLF Power On status. 2 LEDs show the status of the door phones. The EB-6- 1 comes equipped with a local power supply with a 117V AC plug and requires 1 pair cabling to the Main Distri- bution Frame (MDF).
