PSUXE-1 for NO308 and NO61 6 PSUXE-2 for NO820 and N1024

These kits are available through normal distribution channels.

COMMON EQUIPMENT DESCRIPTION

The common equipment is a fully electronic device. It

is essentially a special purpose computer system acting as a communications controller between central

office (CO), private branch exchange (PBX), or

CENTREX supplied lines and the proprietary

telephone stations. The software architecture of the

common equipment provides complete system support and great flexibility of operation.

The common equipment is contained in a functional, modern-style metal housing of contemporary design in keeping with the needs of the modern off ice environment. It is engineered to be wall or rack mounted. The outline dimensions of the common equipment cabinet are illustrated in

Figure

l-1.

STATION DESCRIPTION

The model 67xxx-xx telephone stations are electronic,

microprocessor-controlled devices. They allow not only multiline pickup but also single button access to features available from the serving CO, PBX, or

CENTREX switch as well as the common equipment.

The outline dimensions of the system stations are

illustrated in

Figure 1-3.

The stations provide the following features:

Full modular connection

DSSBLF CONSOLE DESCRIPTION

The DSS/BLF console is an optional device designed to be a companion to a system attendant station in

high call volume situations that require a dedicated

call transfer location. The console provides a direct

station selection (DSS) intercom, and an associated busy lamp field (BLF). It also provides one-key access to all-call when that feature is available.

The console may also be installed at any station port to work in conjunction with a companion station connected to an adjacent paired port.

The model EB32X-xx, DB32-xx, DB32S-xx, DB40-xx and DB70-xx DSS/BLF consoles are all compatible

with the XE system. The station port to which they are

connected must be programmed as a DSS/BLF

console port. The console buttons are fixed for

DSS/BLF operation beginning with station 10 and ending with the maximum station number in the

system. Theses buttons also provide autodial

locations at a second level of storage (accessed with

the HOLD button function). Additionally, any buttons,

from beyond system station capacity through a

maximum of 32, are available as autodial locations at

the first level of storage. For example, a model N1024

key system and a EB32X-xx or DB32-xx console will

fix the first 24 console buttons as DSS/BLF buttons,

and provide the remaining eight buttons as autodial buttons. Plus, it will provide autodial locations at the second level of storage for the first 24 buttons. A total

of 32 autodial storage locations are provided. For

larger consoles, any buttons beyond a maximum of 32

will still be blanked. For this reason, it is

recommended that the larger consoles (DB40 and DB70) not be used unless absolutely necessary since

the XE system has a maximum station capacity of 24

stations thus leaving these consoles with a large

quantity of blanked buttons. The DB32S-xx Adjunct Feature Module can be used

to provide off-hook voice announce (OHVA) to a

station already busy on a call and allow subsequent handsfree answerback (HFAB) by that station user.

The DB32Sxx Module can also be used as a

DSS/BLF console at the same time if desired. The station port to which the Adjunct Feature Module is connected must be programmed for the feature that is required. When both DSS/BLF and OHVA operation are required, the station port to which the console is connected must be programmed as an Off-Hook Call Announce port. When only DSS/BLF operation is required, program the port as a DSS/BLF Console port.

CHAPTER 2

DESCRIPTION OF SYSTEM FEATURES

ACCESS DENIED

Access to particular lines can be denied at certain stations in the system through system programming. This feature is programmable on a per line/per station basis as part of system or administration programming.

ADD-ON CONFERENCE

(2 INTERNAL, 1 EXTERNAL PARTIES)

This system feature allows a station, while operating in

a private mode, to add another station to an outside

call.

ALL-CALL PAGING

(VIA STATION SPEAKERS)

All-call paging allows all of the stations to receive an-

nouncements at the same time through the station speaker. Origination of announcements must be via a station handset. Each station can be programmed to

receive and/or to originate an all-call page. The system default condition is that all stations have both

receive and originate capability. The arrangement of paging as all-call is controlled by both system and ad-

ministration programming. See the discussion titled,

Zone Paging (via Station Speakers).

ALL INTERCOM LINKS

BUSY INDICATION

When all intercom paths are busy, the system causes

the intercom light at each station to be on steady.

AUTO DIAL

Each multiline station provides programmable dialing features. Programmable buttons can be programmed to store numbers for automatic dialing purposes. The stored numbers can be up to fifteen digits in length and can include line or intercom selection, numbers, #, ++, pauses, and flash signals. A pause is stored each time the

stored each time the

pause and flash intervals are programmable. Any

programmable button that does not have a line assign-

ment can be programmed as an auto dial. Additional-

ly, an auto dial number can be stored as a secondary function at every button programmed for direct station

selection. Often used host PBX or CENTREX feature

access codes can be stored at a programmable button

location to provide one-button access to the features.

Also refer to the discussions titled, Automatic Pause In-

sertion, Station Speed Dial, and Programmable DSS/BLE

HOLD

button is pressed, and a flash signal is

TAP

button is pressed. The

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. An auto-save

can be made at a button previously used as an auto-

save button; however, the previously stored number

will be over-written. As many manually dialed numbers

can be saved in this manner as there are separate unused buttons to be used for storage. If a dialed number is!onger than 15 digits, two or more buttons can be used to save portions of it for later chain dialing.

AUTOMATIC ABANDONED

HOLD RELEASE

If a distant party abandons a hold condition and dis-

connects, the central office (CO) will send a forward

disconnect signal to the telephone system. When the key system detects this signal, it will drop the line from

the hold condition and return it to service. The forward

disconnect signal may be either 50 msec. or 350

msec. and the key system is programmable to match this time interval. Both the system and the administration programming can be used to set the time interval

between hang-up and line-drop.

AUTOMATIC HOLD TRANSFER TO INTE.R-

COM (ANSWER HOLD)

If the intercom line is selected while an outside line call is active, this system feature causes the outside call to be automatically placed on hold.

AUTOMATIC PAUSE INSERTION

When the system stores a dialed number for later

redial, it automatically stores a pause whenever the

user waits between digits. The automatic pause is in-

serted in the stored number sequence at the point

where the manual pause in dialing occurred. The wait

time is programmable between 2 sec. and 750 msec.

The wait period is programmable by system or ad-

ministration programming.

AUTOMATIC PRIVACY

(PROGRAMMABLE)

A line can be made private or non-private through

class of service programming. In the private mode, a

station has exclusive use of the line during a call. No other station can access that line unless it is included through the use of the add-on conference feature. In

2-1

Description Of System Features

IMI 66-064 * .

the non-private mode, all stations with that line ap-

pearance can gain access at the same time (some-

times 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.

AUTOMATIC REDIAL OF BUSY

k NUMBER OR UNANSW RED CALL)

Automatic redial of the last dialed number can be made available at every station through button programming. In most cases, the station user must program a button for use as an auto redial button; however, some telephone models provide an Al 6 button as part of the A-button field and this provides an auto

redial function as a fixed feature. With this feature, a

busy number or an unanswered call can be redialed

repeatedly. Once automatic redial is activated, the sta-

tion will select the line, automatically dial the number,

and wait for a response. It will do this once a minute

for approximately 10 minutes. The user must lift the

handset to take immediate control if the call is com-

pleted. Users of the optional speakerphone station can take control by pressing the SPKR button instead of lifting the handset.

AUXILIARY EQUIPMENT INTERFACE

A non-key system telephone device or data device can

be connected ahead of the common equipment on cer-

tain line ports across the tip and ring leads. Special

terminals in the line jack are provided for this purpose.

The system can detect an off -hook condition in the

connected device, and turn on the line status light at

the key system telephone stations with access to the

line to indicate the busy condition.

AUXILIARY STATION RINGER

INTERFACE

The auxiliary station ringer interface provides “dry-contact” relay closures whenever station 17 rings. The contact closures track the ringing pattern of station 17,

and can be used to control an external signalling device. When a particular station port is programmed

to function as a PA port, the auxiliary ringer interface

relay contacts automatically become supervisory contacts. They close when the PA port is called. In this configuration, they are used to enable an external PA

system. Also refer to the discussion titled, Common

Audible Ringer Interface.

BACKGROUND MUSIC

If an external music source is provided, background music can be turned on and off at individual stations. Background music automatically turns off during calls. Also refer to the discussion titled, External Music

Source.

BASIC KEY SERVICE (lA2)

The system provides all of the basic, lA2-type, key

service features. These features are: selective line pickup, common line pickup, multiline pickup, and hold.

BATTERY BACK-UP

(CHASSIS, CABLE, AND BATTERIES)

Battery back-up assemblies including chassis, cable, and battery are offered as optional kits (available from Comdial). The assemblies are designed to connect directly to the un-interruptable power source (UPS) in-

terface located on the common equipment chassis.

No user intervention is required with this feature, and no class of service programming is required.

BATTERY BACK-UP INTERFACE

Provision has been made for attaching a Comdial provided optional battery back-up kit to give full unintenuptable system power in case of an AC power

loss. The switching and trickle charge circuitry are in the common equipment, while batteries, chassis, and cable are packaged as a separate option. When

plugged into an active AC power source the common

equipment will constantly charge the attached batteries with a trickle current. Built-in circuitry automat-

ically switches to battery power when AC power is lost.

With batteries at full charge, a fully loaded system will

operate for a minimum of one hour without AC power.

No class of service programming is required.

CALL ANNOUNCE WITH HANDSFREE

ANSWERBACK

The internal speaker at each multiline station provides

call-announce capability over the intercom link. A . handsfree response to a call-announce call can be made. This response is transmitted by the microphone built into the handset. Also refer to the discussion titled, Voice Announce Blocking

CALL PICKUP - DIRECTED

A user at any station can dial a special prefix code, followed by the number of a ringing station, to answer a

ringing call at that station.

CALL PICKUP - SYSTEM

A user at any station can dial a special code and answer a ringing call at any station in the system. The

feature can be enabled or disabled by system or ad-

ministration programming.

CALL TRANSFER -SCREENED

Screened call transfer allows outside calls to be trans-

ferred from one station to another, via the intercom

link, in one of two ways. If both stations have access

to the line, a common line pickup transfer can be ef-

i’

2-2

Description Of System Features IMI 66-064

fected. If the other station does not have access to the incoming line, transfer can still take place using the system transfer feature. For a screened transfer, a

call is transferred to another station with a pre-transfer announcement by the transferring party. Transferring

of calls is accomplished with the T/C (TRANS-

FER/CONFERENCE) button.

CALL TRANSFER - UNSCREENED

An active call can be transferred to another station without being announced. The transferred call will ring the other station and await an answer. The call will

automatically ring back to the transferring station after

a programmable recall period. A transferred call will only ring if the station is idle. If the other station is

busy on intercom or is already ringing with another call, the transferred call will immediately recall the transferring station. If the other station is idle or has background music enabled, it will start ringing immediately. If it is in any other state, it will not ring until it returns to an idle state.

CALLING STATION IDENTIFICATION

If the station number of a calling station has been programmed into the DSS/BLF of a called station, the calling station will be identified by the flashing BLF light at the called station. The lights adjacent to programmable buttons indicate status of DSS telephones: dark = idle, steady-on = in use, and flash = calling.

CLASS OF SERVICE PROGRAMMING

(EACH LINE AND STATION)

Each line and station in the system can be programmed with a unique class of service operating condition. Class of service programming can be performed using instructions provided in Chapter 4.

CLASS OF SERVICE PROGRAMMING

(FROM MAIN STATION)

Both system and administration class of service (COS) programming is performed from station 10 after a base

level programming step is entered. System COS programming is used by the installer to configure the system and assign the line conditions. Administration COS programming is used by the on-site administrator to re-configure the system as required. Line condition assignment is not a part of administration program-

ming. Refer to Chapter 4 for programming details.

COMMON AUDIBLE RINGER INTERFACE

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 exter-

nal signalling device. When a particular station port is

programmed to be a PA port, the common audible

ringer interface contact points automatically become

supervisory contacts which close when the PA port is called. In this configuration, they are used to enable an external PA system. Also, see the discussion titled, Auxiliary Station Ringer Interface.

DEFAULT FUNCTIONAL PROGRAM

At initial power up of the system, the operating fea-

tures are set to a specific group of operating conditions (default conditions). The default conditions

provide a complete operating system for normal use. The system can be left as a defaulted system or operating conditions can be reprogrammed if desired. A system can be defaulted at any time using the master clear procedure included with the system class

of service programming; however, this action also clears all user stored auto dial and speed dial num-

bers.

DELAYED RINGING

Refer to the paragraph titled, Flexible Ringing Assignments.

DIAL 0 FOR SYSTEM ATTENDANT

The system attendant station (station 10) is signalled whenever the digit 0 is dialed on the intercom line.

DIRECT STATION SELECTION

INTERCOM

Refer to the discussion titled, Programmable DSS/BLF.

DISTINCTIVE RINGING *

The ringing cadence of an incoming call is the same as the ringing cadence of the TELCO, PBX, or CENTREX system. The ringing cadence of an intercom call presents two tone bursts sounded every 4 seconds.

DO NOT DISTURB

Any station can be set to a do-not-disturb mode using the SPKR button. While in this mode, the station will

not ring on any incoming call nor will it accept an inter-

com call. A party making an intercom call to a station set in the do-not-disturb mode hears a fast busy tone. The feature cannot be overridden by the calling party.

DSS/BLF CONSOLE (OPTIONAL)

The DSS/BLF Console is designed to be a companion to any system station. It is useful with high call volume systems whiqh require a dedicated call transfer location. The console provides a one-button direct station selection (DSS) intercom and an associated busy lamp field (BLF). It also provides one-button ac-

2-3

DescriDtion Of Svstem

Features IMI 66-064 ’

cess to system-wide, all-call paging. The console is designed to be connected to any station port and serve as a companion to the station connected to the

adjacent data-paired port. System or administration

programming is used to program a station port as a

DSS/BLF port.

END TO END SIGNALLING

ON INTERCOM

After an intercom call has been established, the system can continue to send dialing signals (DTMF tones) through the intercom path to station ports that are

programmed as OPX unit ports. This feature can be

performed from every station in the system, and is

used by peripherals such as an OPX unit and voice

mail equipment.

END TO ~\DL~~~~ALLING

After an outside call has been established, the system

can continue to send dialing signals (DTMF tones) through the telco network and have them received at

the distant end for inward call completion (bank by

phone, etc.). This conventional, off-hook dialing feature can be performed from every station in the sys-

tem. No class of service programming is required.

EXCLUSIVE HOLD

Exclusive hold prohibits a held call from being

retrieved by any other station. The exclusive hold condition also links the held call to the timed hold recall timeout feature. After timeout, audible and visual sig-

nalling will occur and the exclusive hold condition will

revert to a normal line hold condition. System or ad-

ministration programming can enable this feature.

EXTERNAL PAGING INTERFACE

A station port or line port can be programmed to inter-

face with an external paging amplifier. The paging

amplifier can then be dial accessed through the station

pot-l or directly accessed through the line port from

other stations in the system. DTMF tones can be

dialed through the interface to make a zone selection

if zone paging is provided by the external paging

amplifier. System or administration programming can

be employed to program a station port as an external

paging port. Only system class of service program-

ming can be used to program a line port as an external paging port.

EXTENDED DUAL TONE MULTIPLE

FREQUENCY (DTMF) TONES

The model XE telephone system can access answer-

ing machines, banking computers, voice mail equip-

ment, etc. that require DTMF tones which are longer than the standard 80 msec. tone. A shift to a longer tone of preprogrammed length is automatically made‘

10 seconds after a line is selected or 10 seconds after

the last digit is dialed. A user can shift from one tone

length to the other by pressing the HOLD button and then reselecting the line. It is recommended that the

shortest duration possible be chosen. DTMF generation is a system feature and if several stations are

using the extended DTMF feature at the same time, a

delay in the time between button press and tone

sound may be noticed.

FLEXIBLE LINE ASSIGNMENT

Refer to the discussion titled, Square/non-Square System.

FLEXIBLE RINGING ASSIGNMENTS

Ringing assignments are programmable on a per sta-

tion/per line basis. Ringing can be controlled for every

line that has an appearance at each station. Direct, or immediate, ringing can be programmed for some assigned lines and delayed ringing programmed for others. Direct or delayed ringing is programmed

through system or administration programming.

HANDSFREE ANSWER INHIBIT

The MUTE button on a multiline station can be used to block all handsfree answerback response. This arran: gement 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 speaker light will flash to indicate that this feature is active. Also refer to the dis-

cussion titled, Mute.

HEADSET INTERFACE

A station port can be programmed to allow the operation of special telephones which provide the user with

a headset option. Programming for this feature is

through either system or administration programming.

HEARING AID COMPATIBLE HANDSET

The station handset is compatible with magneticallycoupled hearing aids.

IDLE LINE PREFERENCE

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

2-4

Description Cf System Features

IMI 66-064

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.

I HOLD AND I USE INDICATIONS

The light associated with 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 different flash rate than the indication provided at the other sta-

tions in the system.

INTERCOM CALL PROGRESS TONES

Intercom call progress is marked by special tones. A

steady tone is provided for dial tone. For tone sig-

nalled 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 and returned to the caller as ring-back. When a called station is busy on an outside call, the feed-back supplied to the caller is programmable with class of ser-

vice programming. This feed-back can be either a

ring-back tone or a busy tone. When set for ring-back

tone, the called station sounds subdued ringing during the call. When a called station is busy on the intercom, a busy signal of one tone burst sounded each second returns to the calling station.

INTERCOM LINE LOCKOUT

Refer to the discussion titled, Voice Announce Blocking.

LCD SUPPORT

The common equipment can be field modified with an optional upgrade kit which allow the system to support the use of LCD speakerphones having a Liquid Crystal Display (LCD). The LCD speakerphone ports are identified by system or administration programming.

When a system is modified, the model code of it is changed from an N prefix to a K prefix (i.e. Ni 024 becomes K1024, etc.).

LINE PRESELECTION

A line can be manually selected before lifting the handset (for handsfree dialing) or after the handset is lifted.

LINE TYPE

A line port is programmed as to type. The program. type is chosen based upon the toll restriction that is to be applied to calls made over the line connected to

that port. A line port is assigned as type 1 when any

enabled toll restriction is to be applied with the first digit dialed. Such a line type is often assigned when a CO line is connected. A line port is assigned as type 2

when any enabled toll restriction is to be applied begin-

ning with the second digit dialed. Such a line type is

often assigned when a PBX or CENTREX line with

any trunk access code is connected. A line port is assigned as type 3 when any enabled toll restriction is to be applied beginning with the second digit dialed

whenever the first digit is a 9. If the first digit is not a 9, no restriction is applied. Such a line type is often as-

signed when a PBX or CENTREX line with a trunk access code of 9 is connected. Line types can only be * selected as part of system class of service programming.

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 thirty digits of the last outside number dialed. A newly dialed number will always automatically replace a previously dialed number. Upon command, the system will choose a line and redial the saved number. The system will first choose the prime line if assigned and idle. If it is busy or unavailable, the system will choose any line assigned to idle line preference. If they are unavailable, the system will chose the last line used at the station.

‘!

If it is busy, no further choice is made. Also refer to

the discussion titled, Automatic Pause Insertion.

MANUAL HOLD

A button activated feature at each station will place an outside line on hold. Pressing the HOLD button holds the call, provides a distinctive flash rate of the line but-

ton indicator, and allows the user to access other station features. The holding station or any other station which has access to the line can retrieve the held call.

MEMORY RETE;z;yE-&WITHOUT BAT-

Independent of the optional battery pack, the system

memory is electronically protected during AC power failures by an electronic component sometimes

referred to as a “super-cap”. The stored program data will remain in memory for a minimum of 30 hours provided that the system has been powered con-

tinuously for at least 30 minutes prior to the power failure or disconnection.

Description Of System Features

IMI 66-064

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.

MODULAR WIRING AND JACKS/4-CON-

DUCTOR WIRE SYSTEM

The system can be completely interconnected by employing industry standard 50-pin connectors and modular plug/jack combinations. Station wiring is small, 4conductor, twisted-pair cable throughout the system.

MOMENTARY BUlTONS WITH LED

INDICATORS

The station buttons are momentary contact, press and

release types. They provide line selection, call monitoring, and other feature selection.

tion of the feature selection is provided by solid-state,

long-life, light emitting diodes (LEDs).

Visual indica-

MULTILINE CONFERENCING

This feature will allow one or more multiline stations to access two outside lines at the same time resulting in a conference arrangement. Conference transmission levels are not compensated.

MUSIC INTERFACE (EXTERNAL SOURCE)

A jack is provided on the common equipment for the connection of a customer-provided KX registered

music source. Also refer to the discussions titled, Background Music and Music-on-hold.

MUSIC-ON-HOLD

Music is provided to outside lines that are placed on hold if an external music source is connected to the system and the feature is turned on from station 10. System, administration, or attendant programming can

be used to program this feature.

MUSIC-ON-HOLD SYSTEM-WIDE

ENABLE/DISABLE

Music is provided to outside lines that are placed on hold if an external music source is connected to the system. Music-on-hold can be disabled system-wide

by attendant action. Attendant programming is used to enable/disable this feature. Also refer to the discussions titled: Music Interface, and Music-on-hold.

MUTE

Each station has a MUTE button which, when pressed, will mute the handset transmitter (or internal

microphone on speakerphones) to prevent the user’s voice from being heard by the distant party. The 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.

NIGHT TRANSFER (OF RINGING)

The day, or normal, ringing of incoming lines can be transferred to a particular station or stations (chosen through class of service programming) for off-hour or special purpose answering. The night transfer mode can only be activated from station 10. Night transfer of ringing can be assigned to specific stations using system or administration programming. It is then turned on or off by using system or administration as well as attendant class of service programming.

OFF-HOOK VOICE ANNOUNCE WITH

HANDSFREE ANSWERBACK

With the off-hook voice announce (OHVA) feature, an announcement can be made from one station to another station that is busy on a call. The OHVA announcement is made in a manner that permits the dis-

tant on-line party to hear it and to hear the verbal

response to it unless action is taken with the MUTE button. The OHVA feature is available at stations that are equipped with a multiline telephone and an adjunct

feature module (32-button DSS/BLF console with call-

announce). Two data-paired station ports are required to provide OHVA operation.

An OHVA call is preceded by a ring burst. Then, several quick tone bursts followed by the an-

nouncement are delivered through the loudspeaker in the adjunct feature module. The called party can ver-’ bally reply to an OHVA call in a handsfree manner without interrupting the active call. Reply is made by speaking toward the OHVA microphone included in the adjunct feature module. The distant on-line party can hear this response unless the MUTE button is pressed at the called station to mute the handset transmitter.

A station that has the voice announce blocking feature turned on cannot receive an OHVA call.

Station class of service programming is used to program a station port to be a multiline telephone port and the data-paired port to be a console with call announce port. Also refer to the discussion titled: Secure

Off-Hook Voice Announce.

ON-HOOK DIALING

Every multiline station provides manual and/or automatic dialing while the station handset is on-hook. An internal speaker monitors call progress for completion.

The handset must be taken off-hook to provide the voice link on non-speakerphone stations.

2-6

Description Of System Features

IMI 66-064

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.

A device (such as a model 2500 telephone set or compatible device) that is connected through an OPX unit

to a station port can access both intercom and outside

lines. The system default provides intercom line access when the device goes off-hook. With either prime line alone or prime line and idle line preference enabled through programming, the device connected

through the OPX unit will seize an outside line when it goes off-hook. After going off-hook, the user can get the intercom line by pressing theTAP button. If no digits are dialed after going off-hook, the outside line is dropped when the TAP button is pressed. If digits are dialed after going off-hook, the outside line is placed on hold when the TAP button is pressed.

ORIGINATING DENIED

The ability to originate calls on certain lines can be denied at individual stations through system program-

ming. The originating denied feature is programmed on a per station/per line basis. Originating denied does not prevent a user from answering a ringing line,

retrieving a held call or receiving a transferred call.

Call origination on a line is denied at a particular station by the system or administration programming.

PBX/CENTREX/CENTRAL OFFICE

COMPATIBLE

System features and programmable buttons support the requirements of most PBXs, Central Offices, and CENTREX systems. Numbers, #I’s, +K’s, programmable pauses, and flash signals can be made a part

of every stored number for access to host system fea-

ture codes.

PERSONALIZED RINGING TONE

This programmable feature enables stations to ring in

a distinctive manner with one of four different tones. The ringing tones are combinations of four different frequencies and two different warble rates. Personal ring-

ing tones can be assigned with system or administration programming.

POWER FAILURE TRANSFER

A power failure line connection is available for installing an industry-standard telephone such as a Comdial model 2500-xx. The installed power-fail telephone is

: automatically connected directly across line 1 by the

system whenever there is an AC power failure. Normal origination and reception of calls through the

power-fail telephone is possible during an AC power

failure. The power-fail telephone is automatically dis-

connected as soon as power is restored.

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.

PRIME LINE AUTOMATIC

If a station is programmed for prime line automatic, the

designated outside line or intercom line will be auto-

matically selected when the handset is taken off hook.

Prime line pick up may be pre-empted by preselecting another line before lifting the handset. If the prime line is ringing, it is automatically answered by lifting the handset. Assign a prime line to a station through sys-

tem or administration programming.

PRIVACY RELEASE

A line can be made non-private at a particular station while remaining private at all other stations. This arrangement allows other stations with that line appearance to join that particular station whenever it is on the privacy-released line. A line is specified as

private or non-private at a particular station with system or administration programming. Also see the discussions titled, Add-on Conference and Automatic

Privacy.

PROGRAMMABLE BUlTONS

All multiline keysets are equipped with a minimum of

twelve programmable buttons which can be

programmed a line pick-up, auto dial, station speed ’

dial, and DSS action. Refer to the discussions titled,

Auto Dial, Programmable DSS, And Station Speed Dial. System or administration programming is used to assign functions to programmable buttons.

PROGRAMMABLE DSS/BLF

(DIRECT STATION SELECTION/BUSY

LAMP FIELD)

A multiline station user can store true, one-button, direct station selection (DSS) at any programmable button location to create a DSS button. When this button is pressed, any active outside call is automatically placed on hold and an intercom call is automatically made to that previously stored station number. The visual indicators of the stations programmed at the but-

ton locations form a busy lamp field (BLF). The BLF

conveys station status to the user. An auto dial number can also be programmed as a secondary function at every DSS/BLF memory location. Also refer to the

discussions titled, Tone Or Voice Signaling (Intercom)

and Auto Dial.

2-7

Description Of System Features

IMI 66-064

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.

PULSE/TONE SWITCHABLE

When rotary dial lines are installed, the user can switch from pulse (rotary dial signals) to tone (Dual Tone Multiple Frequency signals - DTMF). This feature is useful for accessing special circuits requiring

DTMF tones such as banking machines, etc. The system is programmed on a per line basis to allow this feature at all stations. The system or administration class of service programming enables this feature on

a per line basis.

RINGING LINE PREFERENCE

The system can be programmed on a per station basis to provide ringing line preference on all lines programmed for ringing at a station.

When ringing line preference is enabled at a station, taking the station off-hook automatically connects it to any outside line which happens to be ringing at the station. A line button will not have to be pressed. The

ability of a particular station to answer a ringing line without line selection is enabled by the system or ad-

ministration class of service programming.

SECURE OFF-HOOK VOICE ANNOUNCE

With the secure off-hook voice announce (SOHVA) feature, an announcement can be made from one station

to another station that is off -hook and busy on a call.

The SOHVA announcement is made in a manner that

prevents the distant on-line party from hearing it or

from hearing the verbal response to it because the

MUTE button must be pressed for reply. The SOHVA feature is available at stations that are equipped with a telephone that includes SOHVA capability. The telephone requires two data-paired station pons to

provide SOHVA operation.

A SOHVA call is preceded by a ring burst. Then,

several quick tone bursts followed by the an-

nouncement are delivered through the handset

receiver of the telephone. Delivering the announcement in this manner prevents the distant party

from hearing it. A station employing a speakerphone

being operated in a handsfree mode will receive a ring burst and can then be taken off-hook to receive the SOHVA call. The announcing caller receives several

tone bursts to alert them that they are making a

SOHVA call and that they may not get a reply should the called party choose to not respond.

Response to the SOHVA call is effected by pressing

and holding the MUTE button and speaking into the

handset. Because the MUTE button is pressed, the

distant party is prevented from hearing the response. The system provides SOHVA operation at every sta-

tion port; however, a station that has the voice an-

nounce blocking feature turned on cannot receive a SOHVA call. Also, on handset equipped telephones, the telephone headset cannot be used to receive a SOHVA call.

Station clas of service programming is used to program a station port to be a multiline telephone port

and the data-paired port as a console with call an-

nounce port. Also refer to the discussion titled: Off-

Hook Voice Announce with Handsfree Answerback

and to the Chapter 3 paragraph titled: Secure Off-

Hook Voice Announce Station found on page 3-11.

SECURE OFF-HOOK VOICE ANNOUNCE

(SOHVA) GROUPS

The ability to receive and originate SOHVA and OHVA

calls is provided to every station in the system. Any

station in the system can send a SOHVA or OHVA call to any other SOHVA or OHVA-equipped station in the

system. Through this feature, the ability of a station to

receive and/or originate SOHVA or OHVA calls can be

disabled through programming so that certain stations

can be grouped together for SOHVA or OHVA calling

between one another while other stations in the sys-

tem are excluded from this group. Stations can be ar-

ranged in up to four different groups for exclusive SOHVA or OHVA calling. For example, the stations of an executive and an assistant can be arranged into .

the same group as follows: Program the executive’s

station for receive in group 1 and program the assistant’s station for originate in group 1. Do not program any other stations to have receive or originate capability in group 1. This arrangement provides exclusive SOHVA or OHVA calling between the two stations. More executive stations can be programmed to

have receive capability in group 1 thus giving the assis-

tant the ability to make SOHVA or OHVA calls to them

as well. These executive stations in group 1 cannot make SOHVA or OHVA calls to one another, however, since they do not have originate capability. Both class of service and administration programming can be used to form SOHVA groups. Also refer to the discussion titled,. Secure Off-Hook Voice Announce and Off-

Hook Voice Announce with Handsfree Answerback.

SELF DIAGNOSTICS

Each station can execute a self test when so enabled. This test verifies processor, indicator, and tone functions. Instructions for activating self diagnostics are provided in Chapter 3, Section 3 of this publication.

SINGLE-DIGIT STATION DIALING

Refer to the discussion titled, System Speed Dial.

SPEAKERPHONE (OPTIONAL)

The optional speakerphone provides handsfree operation of all features, except voice signalled intercom

calls. The handset must be lifted for this purpose.

SQUARE/NON-SQUARE SYSTEM

A system can be programmed to be square or nonsquare as desired. In a square system, a specific line

is assigned to the same button on every station in the system. In a non-square system, any line can be assigned to any available programmable button on every station in the system. Also refer to the discussion titled, Tenant Service. Button mapping for line appearance can be performed on each station using the system or administration class of service programming.

STATION BY STATION PRIVACY

Refer to the discussions titled, Automatic Privacy and

Privacy Release.

STATION SPEED DIAL

Each station can be programmed to provide ten speed

dial numbers at the keypad buttons. Station speed dial numbers can be up to fifteen digits in length and can include line or intercom selection, numbers, #, G++,

pauses, and flash signals. A pause is stored each

time the HOLD button is pressed, and a flash signal is

stored each time the RECALL button is pressed.

SYSTEM SPEED DIAL

Thirty, system-wide, speed dial numbers are provided. The system speed dial numbers can be up to fifteen digits in length, and can include numbers, #‘s, %‘s, pauses, and flash signals. System speed dial number programming can only be performed at station 10; however, once programmed, they can be used at every station in the system. System, administration, or attendant programming can be used to program sys-

tem speed dial numbers.

SYSTEM SPEED DIAL TOLL

RESTRICTION OVERRIDE

This feature makes it possible to override toll restric-

. tion parameters when a system speed dial number is

dialed. With it, it is possible to use toll restriction tables to restrict calls from being made to certain toll

areas yet allow specific numbers in the restricted areas to be called by storing them as system speed dial numbers. With overrride enabled, toll restriction parameters assigned at a station will be overidden when a system speed dial number is called. With override disabled, toll restrictions assigned at a 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 Dialand Toll Restric-

tion - Flexible.

SUBDUED RINGING

Subdued ringing is automatic at any station that is busy on an outside line.

TAP (FLASH/RECALL)

When host system custom calling features are available via a “flash” signal, the system can be programmed so that the TAP button will generate a

“flash” signal when it is pressed. When custom calling features are not available, the TAP button functions as a positive disconnect or dial tone recall button. These two features are mutually exclusive. The flash/recall time is assigned through system or administration programming.

TENANT SERVICE

Two or more closely located sites can simultaneously be served by the same common equipment. Each site

is provided with dedicated trunk facilities and separate

feature and class of service complements. Also, refer to the discussion titled, SQUARE/NON-SQUARE SYS-

TEM. Button mapping for line appearance can be per-

formed on each station using the system or

administration programming.

TIMED HOLD RECALL

After a call has been on hold for a programmed lengih of time, the system will recall the station that placed the call on hold. It also visually signals all other stations. The audible signal is repeated at the end of

each reoccurring time out period. The visual indication continues until the held call is picked up. The system or administration programming sets the timed hold

recall time period.

TOLL RESTRICTION - FLEXIBLE

Flexible toll restriction can be programmed to prohibit some or all stations from calling a wide range of number combinations while allowing specific exceptions.

Restrictions are specified by up to four entries on a deny table while exceptions are specified by up to four entries on an allow table. Allow entries will always override deny entries. Up to eight digits are permitted

for each entry. A “match anything” digit (# symbol) can

be included as part of an entry to represent any digit

from 1 to 0. This is used to deny or allow a range of

numbers with one entry. A separate pre-programmed 1+800 allow table permits this dialing feature to be

2-9

Description Of System Features

IMI 66-064 ’

selected regardless of any restrictions which may be. specified. The dialing of 911 and 1+911 is always al-

lowed. 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 l/O call restriction assignment. When l/O call restriction is selected, l+ 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.

TONE OR VOICE SIGNALLING

(INTERCOM)

Intercom calls can be tone signalled or voice signalfed as desired. The tone signalled intercom call must be answered by lifting the handset. The voice signalled intercom call can be responded to in a handsfree manner. The class of service programming determines

which signalling method is employed as the primary

method when an intercom call is made. The alternate method is available through user action at the station.

Intercom call progress is marked by special tone signals. The system or administration programming determines which type of intercom signalling is first op-

tion signalling for the system. Also refer to the discus-

sions titled, intercom Call Progress Tones and Voice Announce Blocking.

VOICE ANNOUNCE BLOdKiNG

This feature allows the user to block voice announced

intercom signalling by dialing a special code. This fea-

ture, when enabled, also blocks thereception of a

SOHVA call.

ZONE PAGiNG (VIA SiATION SPEAKERS)

Zone paging allows groups of stations to receive an-

nouncements through the station speakers. The programming can enable zone paging in up to three

different zones. A station can be programmed to only

receive announcements or programmed to originate announcements as well. Each station can be programmed to be in any or all zones for both receiv-

ing and originating announcements. The ability of each station to originate and/or receive a page, and the arrangement of the paging into different zones are controlled by system or administration programming. Also, refer to the discussion titled, A//-Cal/ Paging (via

Station Speakers).

the TELCO/PBX jacks must be 25 feet or less as

per FCC requirements. A nominal distance of 7 feet is recommended.

The mounting location must be secure and dry and have adequate ventilation. The temperature range of the location must be within 32-122 degrees F (O-50 degrees C), and the relative humidity must be less than 90 percent non-condensing.

If the mounting surface is damp or if it is concrete or masonry material, a backboard must be attached to

the mounting surface to be used for common

equipment mounting. Suitable mounting backboards are available commercially or can be

constructed out of l/2-inch plywood cut to size. Tools and hardware required:

Fasteners - wood screws (l/4 x 1 -inch round

head), toggle bolts, or wall anchors Screwdriver -to match fasteners

Electric drill - if prepared holes are required Connecting tool - for fastening wires to a type-66

connector block.

Crimping tool - for 623-type modular plugs.

INSTALLATION NOTICE

Per The Underwriters Laboratories regulation 1459,

2nd edition, be aware of the following precautions

when installing telephone equipment that is to be

directly connected to the telephone company network:

Never install telephone wiring during a lightning

storm.

Never install telephone jacks in wet locations unless

the jack is specifically designed for wet locations.

Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.

Use caution when installing or modifying telephone lines.

MOUNTING PROCEDURE

Unpack, and carefully inspect the common equipment and telephones for shipping damage. Notify the shipper immediately of any damages

found. Verify that the packages contain all parts

and accessories needed for proper installation and

operation.

If a backboard is required at the mounting location, attach it securely to provide a stable mounting surface for the equipment.

The common equipment is attached using three

mounting holes located as shown on Figure 3-l.

While refering to Figure 3-1, measure and mark the

location of the mounting holes on the mounting surface.

Drill holes in the mounting surface of a proper size

to accommodate the hardware being used. If

necessary, prepare these holes with inserts, anchors or other attachment devices as dictated by the type of mounting surface.

Insert the top screws into the mounting surface, and tighten them to within approximately l/8-inch of the surface.

Hang the cabinet on the top screws using the mounting holes located on the rear of the cabinet. Note that these holes are elongated with an enlargement at one end. This feature allows the cabinet to slide down on the screws to secure the mounting when the cabinet is hung on them.

Insert a third screw through the mounting tab

located on the lower edge of the cabinet and into the mounting surface, and tighten it into place

Place the individual telephones as desired and in keeping with accepted industry and office standards. A telephone can be wall mounted if necessary as they are desk/wall reversible.

Interconnect the system per the details shown in Tables 3-1 and 3-2 and Figure 3-3 shown at the end of this section

Installation

AC POWER CONNECTION

Employ a dedicated 117VAC 15 AMP circuit, with a

third-wire ground, supplied to a standard electrical

outlet (NEMA 5-15R) for the AC power connection.

AC power connection is illustrated in Figure 3-2

shown below.

A plug-in power line surge protector should be

installed between the power cord and the AC outlet.

Do not connect the AC power cord until the

installation has been checked.

To apply AC power, connect the power cord to the electrical outlet.

BATTERY BACK-UP

The common equipment provides an interface connector for the connection of an optional external battery assembly. This assembly is available separately as a kit.

Be sure that the AC power cord is connected to the electrical outlet before connecting the external battery assembly to the common equipment interface connector. This ensures that Internal protection circuitry Is operating to prevent damage that could result from improper connection.

When charged to full potential, the optional Comdial

model BBUOl external battery assembly provides a minimum of one hour of operation should the AC

power to the system be interrupted. No calls will be dropped when an AC power failure causes the system to automatically switch over to BBUOl operation The BBUOl external battery assembly may include batteries from either of the following suppliers:

- Model PS-1265 from Power-Sonic Corporation, Redwood City CA, 94032.

- Model EP1265-26 from Elpower Corporation, Santa Anna, CA 92704

During AC operation, the common equipment provides re-charging current to maintain the voltage potential of the external battery assembly at an

operational level.

NOTE: The optional external battery assembly

requires approximately ten (10) hours to completely re-charge to full potential after it has been completely discharged and, in some cases, when initially installed.

SYSTEM GROUNDING

The common equipment cabinet has internal secondary surge protection on all line ports. In order

for this protection to be effective, the cabinet MUST be

connected to a reliable earth ground such as a metal

cold water pipe or a building frame ground. The grounding wire must be of #lO or #12 insulated, solid copper and separate from the three-wire AC line cord. A ground stud is located on the common equipment cabinet for this purpose. System grounding is

illustrated in Figure 3-2 on page 3-4.

Figure 3-2. AC Power Connection and System Grounding

LINE CONNECTIONS

The common equipment cabinet line terminations are

standard modular plug/jack connections. Each modular jack (2-6) provides termination for two lines. Modular jacks 2 and 3 also provide termination for an auxiliary pair in addition to the two outside lines. CO line terminations can be at a type 66M-xx connector block or at individual 6-position modular jacks. Table 3-l shows the line connection details.

The line cord that is routed between the CO line termination and the common equipment cabinet termination should be twisted-pair wiring.

Six-wire twisted pair cable is recommended for wiring

between the CO termination and modular jacks 2 and

3 to provide auxiliary equipment interface wiring. Refer to page 3-l 6 for details.

To help ensure that external overvoltage surges do not damage the system, verify that gas discharge tubes or similar protection devices are installed, and properly grounded, on all connected outside lines.

STATION CONNECTIONS

Connections between the common equipment and

the stations for models N0616, N0820, and N1024

are via two type 66M-xx connector blocks which are

cable connected to the common equipment 50-pin

male connectors. Table 3-2a shows the station

connection detais. Station connections for the

model NO308 are via standard modular plug/jack

connections provided on the side of the common

equipment cabinet. These jacks are labeled by station number. Table 3-2b details these

connections.

The maximum distance allowed from the common

equipment to the station when using #24 gauge,

twisted-pair cable is 1500 feet.

NOTE:

If spare conductors exist in the cables that are run between the common equipment 66M-xx connector blocks and the station jacks, it is a good practice to connect them to earth ground. Doing this may help prevent them from inducing radio frequency and/or AC interference into the system.

p5iciEq

The polarity between the individual wires

in a particular voice or data pair is not critical; however, do not connect the voice circuits to the data circuits.

STATION PAIRING Station ports are paired for both data and overload

protection as follows:
