System Description IMI 66-064 CHAPTER 2 DESCRIPTION OF SYSTEM FEATURES AUTO-SAVE FEATURE The auto-save feature can be used to save the last manually dialed number at any unprogrammed button or at a specific button that was previously reserved for this purpose. The button chosen for auto-save must be blank and not currently programmed as a DSS button, line select button, or auto dial button.
IMI 66-064 System Description appearance can gain access at the same time (sometimes known as common line pickup). A line is specified as private or non-private through system or administration programming. Also see the discussion titled, Add-on Conference And Privacy Release. BASIC KEY SERVICE (1A2) The system provides all of the basic, 1A2-type, key service features. These features are: selective line pickup, common line pickup, multiline pickup, and hold.
System Description IMI 66-064 COMMON AUDIBLE RINGER INTERFACE CALL TRANSFER - SCREENED Connections are available at the key service unit which provide “dry-contact” relay closures whenever an incoming line rings. These contact closures track the ringing pattern and can be used to control an external signalling device.
IMI 66-064 System Description programming can be used to program a line port as an external paging port. DSS/BLF CONSOLE (OPTIONAL) EXTENDED DUAL TONE MULTIPLE FREQUENCY (DTMF) TONES The DSS/BLF Console is designed to be a companion to any system station. It is useful with high call volumesystems which require a dedicated call transfer location. The console provides a one-button direct station selection (DSS) intercom and an associated busy lamp field (BLF).
System Description IMI 66-064 LCD SUPPORT automatically connect the station to any assigned line that is idle and has been arranged for this feature. The line button will not have to be pressed. This feature is mutually exclusive with prime line automatic. Programming for this feature is through either system or administration programming.
IMI 66-064 System Description speaker light flashes to indicate a muted condition. The button provides push-on/push-off operation. Also refer to the discussion titled, Handsfree Answer Inhibit. MESSAGE WAITING Special dialing codes enable a station user to control the message waiting (MW) light at other stations in the system. When the message waiting light is turned on at a station, a call can be placed to the originating station to pick up the message.
System Description IMI 66-064 AC power failure. The power-fail telephone is automatically disconnected as soon as power is restored. OPX SUPPORT The system supports the operation of the optional off premises extension (OPX) unit. System or administration programming arranges a station port for OPX operation. POWER ON, VISUAL INDICATION The common equipment has a red LED which monitors the status of the system, and provides an “AC power-on” indication.
IMI 66-064 System Description handset. Because the MUTE button is pressed, the distant party is prevented from hearing the response. PULL OUT DIRECTORY Each desk mounted telephone is equipped with a pull out directory. This directory can be used for recording the system speed dial, station speed dial, or other frequently called numbers. The system provides SOHVA operation at every station port; however, a station that has the voice announce blocking feature turned on cannot receive a SOHVA call.
System Description IMI 66-064 station will prevent it from calling a system speed dial number that matches the restrictions. Class of service programming or Administration programming can be used to enable or disable this feature. Refer to the discussions titled, System Speed Dial and Toll Restriction - Flexible. SINGLE-DIGIT STATION DIALING Refer to the discussion titled, System Speed Dial.
IMI 66-064 System Description Once programmed, flexible toll restriction is assigned on a per line/per station basis. In addition to flexible restriction, or as an alternative to it, stations can be restricted with 1/0 call restriction assignment. When 1/0 call restriction is selected, 1+ 7 digit dialing can be allowed if desired. Either system or administration programming is used to specify the deny and allow entries and assign the restriction to line and station.
System Description IMI 66-064 CHAPTER 3 INSTALLATION SECTION 1 STANDARD INSTALLATION DETAILS • MOUNTING CONSIDERATIONS • The common equipment cabinet should be attached vertically to any sturdy, flat, surface or vertically rack mounted if desired. • Cabinet must be located within four (4) feet of a proper electrical outlet.
