DigiTech C0408 Flexible Station Numbering Plan, Programmability of Features, Intercom Hunt Group

lMl66-083 Description Of System Featf

re-locating the station and line wiring. Line and station class of service programming are used to reassign stations and lines. Also refer to the discussion titled, Auxiliary Ringer Interface.

FLEXIBLE STATION NUMBERING PLAN

The system supports a flexible station numbering plan for individual stations. Each station can be programmed to respond to the dialing of any available number between 10 and 7999. This feature may be used to match the calling number of a station located in a pre-numbered area to that area number. A combination of two, three, or four digit extension numbers can be assigned as long as they do not conflict. For example: If 21 is assigned as an extension number, there can not be any other extension number assigned that begins with a 21. The system class of service programming is used to assign extension numbers to individual station ports.

PROGRAMMABILITY OF FEATURES

Most digital communication system features can be made available at programmable buttons by programming the specific access codes necessary for dialing the features. Programmable features include those that can utilize lamp (on/off) supervision (e.g., call park orbits). All feature access codes can be stored, except for those requiring TRANSKONF button action. Continuous strings of digits can be stored, including ITCM button presses, up to the maximum amount of storable digits allowed in an autodial entry (16).

HANDSFREE ANSWER INHIBIT

The MUTE button on a station can be used to block all handsfree answerback response. This arrangement will prevent a station user from monitoring another station site using the monitoring ability of the voice announce feature. When the button is pressed, all handsfree answerback is disabled thus inhibiting any off-site monitoring. The MNlR (SPKR) light will flash to indicate that this feature is active. Also refer to the discussion titled: Mute.

IDLE LINE PREFERENCE

When a station is programmed for idle line preference, it will automatically be connected to the first assigned idle line. The system can be programmed on a per station basis to enable idle line preference. When idle line preference is enabled, taking the handset off-hook will 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. If this feature is used in conjunction wfth prime line automatic, the user will be given prime line first when going off-hook. An idle line will be given if the prime line is in use. The station class of service programming enables this feature on a per station/per line basis.

INTERCOM CALL PROGRESS TONES

Intercom call progress is marked by special tones. A steady tone is provided for dial tone. Ring-back tone is one second on and three seconds off. For tone signalled intercom calls, a two-tone burst is sounded every four seconds at a called station and returned to the caller as ring-back. For a voice signalled intercom call, a single tone burst is sounded at a called station. When a called station is busy, a busy signal of one-half second on and one-half second off is received at the calling station. A fast busy tone will be supplied when the called station is in the do not disturb mode. OPX ports are only supplied with the regular busy tone since fast busy tones could interfere with the operation of some accessories that can be connected to this port.

INTERCOM HUNT GROUP

Station ports can be assigned to intercom hunt

groups. When a station that is assigned to a hunt ’ group is busy or is a ring-no-answer (RNA), a call to it will ring at the next idle station in the group. A hunt group can be terminal or circular. A call will route down a terminal group from the called station until it finds an idle station or reaches the end of the group. A call will search around a circular group until it encounters an idle station or until all stations in the circular group are searched. The ringing time at any one station is programmable. Hunt groups are created through station class of service programming.

The light associated wtth a line button provides a visual indication of the status of that line. When a station user has a line in-use or on-hold at a station, the light indication provided at that station is of a diierent flash rate than the indication provided at the other stations

in the system. No class of senrice programming is required.

INTERCOM LINE TIMEOUT

Should the intercom line be selected with no dialing or other action taking place, the intercom will timeout after ten seconds, and return to an idle state.

LAST NUMBER REDIAL

Each station is provided with a last number redial feature. This feature will save 32 digtts of the last outside number dialed. A newly dialed number will
