Features:

ACCOUNT CODE ENTRY
Account codes of up to 16 digits (16 or 13, see below) are incorporated in the call records generated by the Station Message Detail Recording (SMDR) option and provide a reference for billing.

ACCOUNT CODE - FORCED/VERIFIED/UNVERIFIED
Account Code - Forced Verified requires selected station users to dial an Access Code and a verification code before making an outgoing call. The outgoing call is processed only after the dialed Account Code is verified. Account Code - Forced Unverified requires selected station users to dial an access code and an unverified Account Code before making an outgoing call. The outgoing call is processed only if the unverified Account Code is dialed. This feature allows a system administrator to control unauthorized outgoing calls. The Forced/Verified Account Code is part of the Station Message Detail Recording (SMDR) call record. An Account Code has a maximum of 13 or 16 digits.

ADD-ON CONFERENCE
This feature allows a conference call with a maximum of four parties with various combinations of outside lines and stations. This increases efficiency by allowing multiple parties to enter a conversation.

ALL CALL PAGE
This feature allows simultaneous paging (internal and external) over the built-in speaker of all idle Multiline Terminals in a zone. This enables a person, away from the station being called but within hearing distance of a Multiline Terminal or external speaker, to respond to the paging call.

ALPHANUMERIC DISPLAY
The Electra Elite IPK Multiline Terminals with display have a 24-character by 3-line LCD. These displays provide information such as: date/time, elapsed call time on outside calls, digits dialed, internal calling party number, Customized Message, Speed Dial entries, or soft keys.

ANALOG LINE EXTENDER (Dterm Analog EXT)
This feature allows a user with a DTP-32DE-1 Multiline Terminal to make or receive calls from a remote location while maintaining a station appearance from the office KTS (Key Telephone System).

ANCILLARY DEVICE CONNECTION
This feature allows installation of selected peripheral (ancillary) devices such as a tape recorder on any Electra Elite IPK Multiline Terminal, with an optional AD(A)-R Unit. An optional AP(A)-R Unit adapter allows connection of single line equipment such as a single line telephone, modem, automatic dialer, cordless telephone or other compatible device for original call only. These terminals have a built-in headset jack to allow handsfree operation. The Analog Port Ringer Adapter, AP(R)-R Unit, allows connection of single line equipment such as a Single Line Telephone (SLT), modem, facsimile machine, automatic dialer, answering machine or other compatible analog device.

ANSWER HOLD
This feature enables a Multiline Terminal user to press the flashing Answer (ANS) key to answer incoming ringing calls on a CO line key. If the Multiline Terminal user is already engaged in a call, the first call is automatically placed on Non-Exclusive Hold when the second call is answered. Answer Hold is particularly useful at Attendant Positions or other central answering positions. Using the Answer (ANS) key speeds call handling and Answer Hold prevents accidental call dropping.

ANSWER KEY
Multiline Terminals have an Answer (ANS) key and associated LED. The LED flashes when the Multiline Terminal user receives an incoming CO/PBX, Tie/DID transferred or CO/PBX transferred call. When multiple calls are received, the Answer (ANS) key is used to pick up calls. The LED continues flashing until the last unanswered call is answered. Press the Answer (ANS) key during a call to hold the current call and allow the next call to be answered.

ASSIGNED NIGHT ANSWER (ANA)
ANA allows CO/PBX lines to be programmed to bypass the attendant and ring directly at a selected station or tenant. A separate Direct Inward Termination (DIT) ringing assignment is available for Day Mode.
System Software S4000 or higher is required to support
delay ringing to ANA or to ANA trunks to a tenant.

ATTENDANT ADD-ON CONSOLE
This Console functions in conjunction with a Multiline Terminal programmed as an Attendant. Each console provides access to a maximum of 48 stations and/or outside lines. The Busy Lamp Field status is shown as a red LED for each station or trunk. These trunks can include CO/PBX, DID, ISDN, E&M Tie Lines, T1 lines and VoIP Trunks. The Attendant Add-On Console also has 12 function keys that can be used for attendant messaging or paging access. The Electra Elite IPK supports up to four Attendant Add-On Consoles per system. A single station within the system supports a maximum of four consoles.

ATTENDANT CAMP-ON
This feature allows a call to be transferred to a busy station and is used at an Attendant Position with an Attendant Add-On Console. Press the Transfer (TRF) key on the Attendant Add-On Console to send the camp-on tone to the busy station. When the station receives the camp-on tone, the call rings and can be answered. If the camped on call is not answered in a preprogrammed time, it recalls to the Attendant Position.

ATTENDANT POSITIONS
Any number of stations can be designated as Attendant Positions. These stations have access to distinct Attendant-type features. Two Attendant Positions can support two Attendant Add-On Consoles each. Attendant features such as setting Night Mode and System Speed Dial memory programming apply.

ATTENDANT STATION OUTGOING LOCKOUT
This feature allows an Attendant Position with an Attendant Add-On Console to set a predetermined Code Restriction Class Assignment to any station that is assigned on the Attendant Add-On Console. This allows the Attendant to set/reset restrictions to a station to disallow outgoing calls.

ATTENDANT TRANSFER
This feature permits efficient call transfers within the system using an Attendant Multiline Terminal equipped with one to four Attendant Add-On Console(s). Transferred calls can be voice announced, camped on (if the station is busy), or directly transferred to ring at stations. All unanswered transferred calls return to the Attendant with distinct audible and visual indications after a programmed time.

AUTHORIZATION CODE
Permits a station to dial outside numbers that would otherwise be restricted. When an access code plus Authorization Code is dialed, the station code restriction class temporarily changes to allow calls when permitted by a new code restriction class. The Authorization Code can be verified or unverified based on class of service and is assigned in the Forced/Verified Account Code table (these share the same table). The Authorization/Account Code is part of the Station Message Detail Recording (SMDR) call record.

AUTOMATED ATTENDANT
This Attendant answers incoming CO/PBX calls and sends a greeting message for calling parties. When the caller enters a station number or a 1- or 2-digit number from the dial pad as instructed in the greeting message, the Automated Attendant then transfers the call to a designated station or station hunt group. The Automated Attendant can be set to provide eight automated message levels.
Installation of a VRS(4)-U10 ETU is required.

AUTOMATIC ANSWER WITH DELAY MESSAGE
This feature answers incoming CO/PBX calls and plays a specified message to the outside caller while still ringing designated stations. One or two messages can be played to the outside caller. Message(s) played are the same as the Automated Attendant Message(s).

AUTOMATIC CALL DISTRIBUTION (ACD)
Automatic Call Distribution forwards any incoming call (DIT, ANA, DID, or CO Ring Transfer) to a prearranged ACD Group of Agents. An incoming call is distributed to the Agent of the ACD Group that has been idle the longest. The ACD feature has four distinct parts: Call Distribution, Agents and Supervisor Function, Status screens and Management Information System (MIS) reports, and Delay Announcement.

AUTOMATIC CALLBACK
After receiving a call waiting tone from a busy station, a user can set an Automatic Callback. When both stations are idle, the system signals the Automatic Callback originator first and, after a response, signals the other station.

AUTOMATIC DAY/NIGHT MODE SWITCHING
This feature allows the system to be programmed to switch automatically into or out of the Night Mode at a preprogrammed time. Night Mode does not have to be manually set/reset daily. After a preprogrammed time, the system automatically switches back to Day Mode.

AUTOMATIC HOLD
This feature activates when an Attendant with an Attendant Add-On Console presses a DSS key programmed for station or page access while engaged in an outside call. Automatic Hold also activates during an outside call when a Multiline Terminal user presses a Feature Access key or One-Touch key programmed for Direct Station Selection or Direct Paging Access. This feature reduces the risk of accidentally disconnecting a call due to incorrect operation and simplifies access to various features by reducing required operational steps.

AUTOMATIC NUMBER INDICATION (ANI) ON T1
T1 ANI displays the calling party telephone number on the LCD of the Multiline Terminal for calls on a Feature Group D T-1 span. ANI information follows the call to wherever it is transferred. This feature is functionally the same as Caller ID.

AUTOMATIC REDIAL
This feature simplifies repetitive dialing to a busy or unanswered outside party. When receiving a busy tone or no answer while attempting to make an outside call (CO/PBX), the system periodically redials the party number while the station use monitors the call for completion.

AUTOMATIC RELEASE
This feature releases the outside line circuit after an outside party abandons the call. For this feature to work with Loop Start Trunks, the CO/PBX providing the outside line must provide a timed disconnect signal. Automatic release is normally provided on Ground Start Trunks, E&M Trunks, ISDN Trunks, Tie/DID, and VoIP Lines.

AUTOMATIC ROUTE SELECTION (ARS)
This feature allows an outgoing line to be seized using a Trunk Group or Route Advance Block (RAB) for each number dialed by the user. ARS allows better use of trunks connected to the system.

AUTOMATIC TRUNK-TO-TRUNK TRANSFER
This feature allows an incoming CO/PBX call to be automatically dialed out of the system over another outside line to a preprogrammed telephone number. This is especially useful to forward calls to an answering service during non-business hours ( i.e., nights, weekends or holidays).

BACKGROUND MUSIC OVER EXTERNAL SPEAKERS
This feature provides music over external speakers for enhancement of the work environment. The ECR-U10 ETU interrupts background music during an external page.

BACKGROUND MUSIC - MULTILINE SPEAKER
This feature allows the Multiline Terminal user to dial a code to enable one of three music sources to play through the idle terminal. Paging, incoming voice announcements, rings and recalls override the music.

BARGE-IN
This programmable feature allows selected Multiline Terminal users in the system to override another station user conversation with or without alerting that station user. The alert tone is a programmable option.

BATTERY BACKUP - SYSTEM MEMORY
A battery backup retains System Program Memory during a power outage. When fully charged, the battery maintains backup power for approximately 21 days. System Data, Speed Dial Memories and Clock/Calendar are among the functions protected by the backup battery. When power is restored, the system returns to normal operation. The battery is continuously charged while the system is operating on commercial power.

BATTERY BACKUP - SYSTEM POWER
A built-in battery temporarily provides complete system operating power during commercial power outages. Operating time on the backup battery is approimately 30 minutes on systems configured for 64 ports and approximately 15 minutes on systems configured for 144 ports. If optional (locally provided) batteries are connected and fully charged, full system operation can be maintained for an extended time. Actual time depends on system configuration, traffic conditions and the capacity of the batteries being used. The built-in or external battery is continuously charged while the system is operating on commercial power.

BUSY LAMP FIELD (BLF) ON MULTILINE TERMINALS
The BLF feature indicates station status with an LED. The LED lights when Feature Access keys and One-Touch keys are programmed for Direct Station Selection (DSS). The 32-key Electra Elite IPK Multiline Terminals and 32-key Dterm Series i Multiline Terminals are the only terminals supporting BLF on One-Touch keys. This allows Multiline Terminal users to determine at a glance if a station is in use.

CALL ALERT NOTIFICATION
This feature allows station users to receive an alert tone, flashing ICM, Large LED and LCD identification when an incoming caller has called and the user station is busy. This allows the station user to put the current call on hold to answer a second call, increasing call handling abilities.

CALL APPEARANCE (CAP) KEYS
This feature automatically places an outside call on a Call Appearance Key if the call is answered. These keys can be assigned on any Multiline Terminal. The user can press the applicable CAP that is flashing on any station with the same appearance to retrieve the call. This feature allows efficient call handling when numerous CO calls are received with only a limited number of available CO line key appearances.

CALL ARRIVAL (CAR) KEYS
CARs are software extensions. A Call Arrival Key is assigned to a line key and can appear and ring on an individual or multiple stations. When a call is directed to the CAR, any station with the CAR appearance can answer that call. This ensures that every call is answered promptly. CAR keys use system extension numbers and are assigned in groups of four. Call Arrival and Call Appearance keys often work together to provide solutions to unique applications.

CALLBACK REQUEST
A Callback Request can be set to any Multiline Terminal to notify the user that another station wants a call returned. Users of Multiline Terminals can receive a maximum of three Callback Requests from other station users. Non-display Multiline Terminal users receive a Feature (or FNC) LED indication when a Callback Request is set. Single Line Telephone users can set but not receive a Callback Request.

CALLER ID INDICATION
This feature displays the calling party telephone number or name on the LCD of the Multiline Terminal for incoming CO calls. Up to 16 extensions can display Caller ID on incoming calls, and after the call is answered, Caller ID can be displayed at the station that has the CO call.

CALL FORWARD - ALL CALL
This feature forwards all calls directed to a station, to another station, Voice Mail system or to the Attendant. This allows a station to be left unattended and still have the calls answered at another location. Call Forward - All Call can be set or canceled at the destination station. Attendant Positions can be used to cancel Call Forward -All Call system-wide.

CALL FORWARD - BUSY/NO ANSWER
This feature forwards calls directed to a station, to another station, Voice Mail system or to the Attendant Position when there is a Busy or Ring No Answer condition. This allows calls to be routed to another station or to the Attendant Position.

CALL FORWARD - DISPLAY
