For larger consoles, any buttons beyond a maximum of 32 are blanked. Since the XE system has a maximum capacity of 24 stations, Comdial does not recommend the use of the larger consoles such as DB40 and DB70 because these consoles will show a large quantity of blanked buttons.

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 administration programming. See the discussion titled

Zone Paging (via Station Speakers).

Auto-Save Feature

The auto-save feature can be 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 autosave 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 longer 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 disconnects, 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 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.

Autodial

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 HOLD button is pressed, and a flash signal is

stored each time the TAP button is pressed. The pause and flash intervals are programmable. Any programmable button that does not have a line assignment can be programmed as an auto dial. Additionally, an auto dial number can be stored as a secondary

function at every button programmed for direct station

selection. Often used host PBX or access codes can be stored at a programmable button location to provide one-button access to the features.

Automatic Hold Transfer To Intercom

(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 lnsertlon

When the system stores a dialed number for later

redial,

it automatically stores a pause whenever the

user walts 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 the non-private mode, all stations with that line appearance can gain access at the same time (sometimes known as common line pickup). A line 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

Number Or Unanswered 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; how-

ever, some telephone models provide an Al 6 button

as part of the A-button field and this

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 station will select the line, automatically dial the number,

and watt for a response.tt will do this once a minute for approximately 10 minutes. The user must lii 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.

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-

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

For a screened transfer, a

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.

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 external 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 features are set to a specific group of operating conditions (default conditions).

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 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-

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.

Timed Hold Recall

After a call has been on hold for a programmed length 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

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 selected regardless of any restrictions which may be specified. The dialing of 911 and 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, 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.

Tone Or Voice Signalling

(Intercom)

Intercom calls can be tone signalled or voice signalled 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 man-

ner. 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 option signalling for the system. Also refer to the discussions titled Intercom Call Progress Tones and Voice

Announce Blocking.

Voice Announce Blocking

This feature allows the user to block voice announced intercom signalling by dialing a special code. This fea-

ture, when enabled, also blocks the reception of a

SOHVA call.

Zone Paglng (Through Station Speakers)

Zone paging allows groups of stations to receive announcements 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 receiving 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

Mounting Considerations

Attach the common equipment cabinet vertically to

any sturdy, flat, surface or vertically rack mounted if

desired.

Locate the cabinet within four (4) feet of a proper electrical outlet. The system requires a dedicated

117VAC

supplied to a standard electrical outlet (NEMA

515R).

The distance between the common equipment and 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

(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, you must attach a backboard to the mounting surface to be used for common

equipment mounting. Suitable mounting

backboards are available commercially or can
