Common Equipment Description

The common equipment base unit 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

telephone stations. The software architecture of the common equipment provides complete system support

and great flexibility of operation. The system is fully digital and is ISDN up-gradable

with two usable time slots available for each station. The digital information passes over time division

multiplexing (TDM) highways. The digital information

is an encoded version of the voice transmission and

control signals that are translated into computer

language. The TDM highway can transmit several

signals over a single pair of wires at the same time. The signals are governed by a system clock. This

clock creates an overall point of reference against

supplied lines and the proprietary digital

which the TDM information is synchronized and partitioned into time slots. A time slot is a portion of time assigned to a particular position of the system clock. Each time a particular clock position is reached,

the information associated with that position can be

read. As the system clock goes through the clock cycle, all necessary digital information is passed between the pieces of equipment sharing the highway.

The common equipment consists of a base unit, which

provides complete feature support, and optional expansion modules which provide extended station and line coverage.

The common equipment is contained in a functional,

modem-style metal housing of contemporary design in

keeping with the needs of the modem off ice environment. It is engineered to be wall or rack mounted. The outline dimensions of the common equipment base units are illustrated in

Account Codes

(With Forced Positive Verification)

System users can employ account codes to identify

calls by category or by any other desired grouping so that the system can print reports. The account code entry can be voluntary or, beginning with software

release 13A, the programmer can arrange the system

so that the users are forced to enter an account code

before they can make an outgoing call. The system

compares the account code entered by a station user with a list of programmed account entries.

The programmer must program the system so that it verifies an entered account code as valid. If he or she

enables verification and the system cannot match an

account code that a user has dialed with the

programmed account code entries, the system will

sound an error tone if account code entry is voluntary,

or it will prevent the user from further dialing until he or

she enters a matching account code if account code

entry is forced.

A user must enter an account code either.before

dialing an outgoing call or after the distant party on an

incoming call has hung up. Additionally, users may enter an account code before they select a line for an outgoing call if they wish. When they enter an account code without a line selection, the code will apply to any

line they subsequently select at that station. On

incoming and outgoing calls, the user who enters the account code is associated with the call record except when the call is transferred. On transferred calls, the

transferee is associated with the call record. As a feature to LCD speakerphone users, the

programmer can arrange for a message to appear in

the telephone’s display to prompt the user to enter an

account code during incoming or before outgoing calls. He or she can also assign the length of time that the display appears. The user must enter account code digits after the message appears. If the programmer has set the system to verify code entry, it then makes a verification attempt. If the system cannot verify the

account code it causes the display to show an error

message. The user may then re-enter the account

code at this point. If the verification attempt is successful (or if the system does not require that the code be verified), the display will return to its normal

date and time message. If the account codes are

forced and the call is outgoing, then the line is dropped

at the end of the display time if the user has not entered a valid account code. The programmable

range for the display time is 1 to 20 seconds. When the feature is not enabled, the system inhibits the display prompt.

When a station user activates the last number redial or automatic radial features for outgoing calls, the system will automatically re-use the last account code the user entered at that station unless he or she enters a new one before activating the redial feature.

In addition to turning on the account code feature, enabling its verification, and making it either voluntary

or forced, the programmer must set the account code length, specify the number of digits that the system will

verify, and make up the entire list of account codes that the users will use. Account code length defines the number of digits that a user must enter before the system will accept the code. The length can range from three to 16 digits but cannot be lower than the verified account code length. The verified account code length defines the number of digits that the system will verify before it accepts an account code as valid. As well, verified account code length defines the

number of valid account codes that a programmer can

store (as shown in the following table). A programmer should be aware that when he or she changes the verified account code length, the system automatically empties the list of valid account codes.

Even though a programmer has arranged a system to force users to enter account codes before making calls, they can always dial certain programmer-defined emergency numbers without an accompanying account code entry. The system allows a maximum of three programmable emergency numbers. The

minimum length of an emergency number is 1 digit

Account Code Button

A programmer can use station class of service

programming to assign an account code button to any programmable button location at a station as part of

the button mapping procedure. With this account code

button available, the user can press it and then dial an account code without interrupting the call. Only the user of the Account Code button will hear the DTMF tones when he or she dials the code. The distant on-line party will not hear the DTMF tones, and the system will not place the line on hold. The user can hear the distant on-line party while he or she is dialing an account code. If the telephone does not provide an account code button, the user must dial an intercom code before he or she dials the account code digits.

Analog Terminal Interface Support

With software release revision 8, the digital telephone system supports the operation of the Analog Terminal

Interface (ATI-D). The ATI-D is a multipurpose on-premise accessory with dual circuits that provide an industry-standard telephone interface. This feature adapts most industry-standard (IST) devices and the

ExecuMail voice processing system to the digital

telephone system. The ATI-D accepts both tone and

pulse (rotary) dialing from these devices. Each ATI-D circuit will drive a load with a maximum ringer equivalence number (REN) of 2.0 thus allowing more than one IST connection at each ATI-D circuit input. The ATI-D supports a wide variety of IST equipment such as model 500 and 2500 telephones, cordless

telephones, answering machines, and FAX machines.

The ATI-D is housed in a metal enclosure powered by the telephone system through the station

port connections. It contains a ringing generator to

generate a ringing signal for the IST devices.

Automatic Dialing Of Stored Numbers

Automatic Dialing

The system supports up to 22 automatic dial (autodial)

numbers per station. Autodial buttons can store up to 16 digits plus an intercom or line selection. Stored

digits include 9-0, +# and #. The system stores a

pause at any point where the HOLD button is pressed, and stores a hookflash at any point where the TAP button is pressed. Automatic dialing provides a way to obtain one-button access to frequently used system features. This feature does not require any class of service to enable it.

Programmable DSWBLF

A station user can store one-button, direct station selection (DSS) at any memory button location to create a DSS memory 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 button locations form a busy lamp field (BLF). The BLF conveys station status to the user. An autodial number can also be programmed as a secondary function at every DSS/BLF memory location. No class of service is required.

Station Speed Dial

Each station provides 10 speed dial number locations at the keypad buttons. Station speed dial numbers can be up to 16 digits in length and can include line or

intercom selection, numbers, #, hookflash signals. A user can store a pause by pressing the HOLD button and store a hookflash signal by pressing the TAP button.

System Speed Dial

The system provides 99 system-wide speed dial

Auxiliary Equipment Interface

An installer can use the auxiliary equipment interface to connect a telephone device or a data device to an outside line ahead of the common equipment. The system can detect an off-hook condition in a device that an installer has connected to the auxiliary equipment interface, and turn on the status light for that line at telephones that have that line appearance.

It does this to indicate that the line is busy and not available for station use. Auxiliary equipment interface

connections provide connections to lines 2 and 4. A

user cannot interrupt an external device by pressing

the line button unless the line has been programmed

to be non-private.

on~the-common equipment chassis. The system does

not require any action from the telephone user to

make it operate on battery power nor does it require any class of service programming action on the programmer’s part.

Battery Back-Up Interface

The common equipment cabinet provides an interface for an optional battery back-up kit to give full

uninterrupted system power in case of an AC power loss. The switching and charge circuitry are in the common equipment, while the 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. Built-in circuitry automatically 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.

Call Costing And Station Message Detail

Accounting Reports

The system provides built-in, estimated costing of all outside calls. It also provides station message detail accounting (SMDA) printout reports of all costed calls

as well as displaying call costs on LCD speakerphones.

Call costing, in general, provides a means of establishing costs to be applied to outside calls made from system telephones. Call costing computes charges for a call after it is completed. It does not

restrict dialing as toll restriction does. Call costs are

based on a two-tier time rate and includes a line

surcharge cost. A programmer can program

allowances for call set-up and minimum call duration. The system provides several ways of determining call

costing making it is possible to apply reasonable rates for the entire country.

The system will automatically provide a report

whenever the costed call storage reaches 95 percent

previously generated reports. The programmer can

take programming action to always delete the records

after they have been printed. The attendant has the ability to request particular reports to be printed at any

time they are required. The programmer can establish account codes to allow

system users to identify calls by category or by any other desired grouping so that the system can report costing by that category or grouping. Further, the

programmer can define department numbers and assign stations to different departments so that the

system can produce call cost reports on a department-by-department basis.

Programmers must use call costing and SMDA

reporting class of service programming to set the costing features, and assign stations to specific SMDA departments using the station class of service programming. He or she can also enable the LCD speakerphone display of costed calls through station class of service programming.

Description Of System Features

Call Forwarding

This feature allows a station user to designate another station or the attendant station as the recipient of all

calls normally directed to ring at his or her station. If

the user has call forwarding enabled when the

attendant activates night transfer of ringing, the system users station. Calls that the system forwards to a recipient station can be forwarded again by that station user to another station. Thus, two levels of call

forwarding on all calls can occur, first, from station A

to station B and then, from station B to station C. As a

reminder that call forwarding is enabled, a short tone burst will occur at the user’s station for each intercom call that it receives while its calls are forwarded.

When the programmer has assigned a call forward

button to a station, its associated LED will turn on to

indicate that the feature is enabled when the user

presses it; however, if the call forward button is

programmed as a second level to a DSS/BLF button,

the system reserves the LED indication for BLF

indication. On LCD speakerphones that are recipients of call forwarding, the display will indicate the extension number or station name for the station from which an intercom call was forwarded.

Call Forwarding - Personal

Call forwarding of personal calls allows a station user to designate another station number (or the attendant

station number) to be the recipient of intercom and

prime line calls normally directed to that user’s station.

For each intercom call received while call forward is enabled, a ring reminder (short tone burst) will be sounded at the forwarding station to remind the user

that his or her calls are being forwarded. On LCD

speakerphones that are recipients of call forwarding,

the display will indicate the extension number or

station name for the station from which an intercom call was forwarded,.

Call Pickup

Directed Call Pickup

A station user can dial a code, followed by the

extension number of a ringing station, to answer the

ringing call.

Group Call Pickup

If a call rings to any station in a pre-programmed group and another user in the group wishes to answer

the call, that user may dial the group pickup code and

answer the call. Four different groups can exist with any number of stations in a group. Overlap is provided by allowing stations to be in more than one group thus enabling those stations to pick up for stations in more

than one group. The programmer must place the

system stations in logical answering groups by group

them together using the station class of service

programming.

Screened Call Transfer

Screened call transfer allows station users to transfer outside calls from one station to another, via the intercom link, in one of two ways. If both stations have access to the.line., a user effects a common line pickup

transfer. If the other station does not have access to the incoming line, the user uses the

transfer/conference button to effect the transfer. For a

screened transfer, the transferring user precedes the

transfer with an announcement to the party that is to

receive the transferred call.

Unscreened Call Transfer

A user can transfer a call to anotherstation without first announcing it. The transferred call will camp-on to the other station where it will ring and await an

answer. The call will automatically ring back to the transferring station after a programmable recall period.

There is no limit as to how many calls users can

camp-on to another station. A transferred call will only

ring if the station is idle. If the station is busy, the call will wait until it is idle before it rings. The programmer can use the system class of service programming to set the recall time for an unanswered transferred call.

Unanswered Call Transfer Recall Timing

A transferred call that is unanswered after a pre-programmed length of time will return to the station that transferred it. The system will return the call to both attendant stations when the tandem attendant feature is enabled. When LCD

speakerphones are employed, the display will show the station number or name as well as the line number that is being recalled. The system class of service

programming determines the recall time for an

unanswered call transfer.

A telephone user can signal a busy station with the

call waiting tone to indicate that he or she wishes to

contact them. Users dial a special code to activate the

call waiting tone.

Caller Identification (ID) Service Support

The central office sends caller ID data along lines that

it has assigned to the Caller ID service. Caller ID information is displayed at a system LCD

speakerphone only if the programmer assigns it to the

Caller ID service, and then only for those Caller ID lines that are assigned to that station and arranged to

perform as follows:

l ring audibly

can be answered by user pressing button for the

ringing line

are transferred to the station fhe station receives Caller ID data for a call between the first and second rings. A programmer can enable the first ring for a line assigned to Caller ID to be either audible or silent. Selecting the “silent” option insures

that the Caller ID data is displayed prior to ringing,

which nearly eliminates the loss of Caller ID data due to premature answering.

Station users may automatically retrieve and dial the

last Caller ID number displayed at a station by using a preprogrammed SAVE recovery button. Because the programmer can store the local area code and up to 100 6-digit area code and local office codes, ten-digit Caller ID numbers can automatically be transformed

into a format that can be dialed (seven-, eight-, and eleven-digit Caller ID numbers are already in a format that can be dialed and do not need to be transformed).

The system will dial those numbers that are present in the 6-digit table as local calls even if they are in

different area codes.

All Caller ID features require that the Caller ID decoder device (product code CID08) deliver Caller ID data to the system’s RS-232 data port B. The programmer

must configure this port to match the output of the Caller ID decoder device. The recommended configuration is 9600 baud, with eight data bits and one stop bit. He or she must use VDT programming

to do this.

Caller ID distribution is in the form of messages which specify the Caller ID data for lines with incoming calls, and identify the stations answering such lines. The data is in the ASCII format and is suitable for use with PC-based application programs.

If a user has stored the station number of a calling

station into the direct station select/busy lamp field

(DSWBLF) of his or her station, the flashing of the

corresponding BLF light will identity the caller. The

BLF lights also indicate the status of the.DSS

telephone using the department pilot number.

Class Of Service

Block Programming

A programmer can assign a particular line or station’s class of service to an entire block of lines or stations with one programming action. This feature eliminates

the need for him or her to individually program stations

and lines with the same class of service. A programmer can perform a block programming class of service after he or she has programmed a station

class of service or line class of service for a particular

station or line.

Class Of Service Programming

Class of service (COS) programming is used by the installer/programmer to configure and assign all system, line, station, and special purpose operating features. The installer/programmer enters COS programming by dialing an access code over the intercom line. System administrators can enter COS programming with another code to reprogram any system, station, or special purpose operating feature that may require change at a later date. Line

reprogramming ability is not available through system administration programming. The system attendant can reprogram certain system-wide features that

require periodic change by entering COS

programming with another code provided for this

purpose. The station user can program individual

stations for speed dial, autodial and direct station

selection (DSS) by entering COS with a code provided for that purpose. Thus, COS programming is arranged with a hierarchical order from the highest(the

installer/programmer) to the lowest (the station user)

level with a higher level programmer having the ability to do anything a lower level programmer can do without exiting a current programming mode. However, only the station user can program the speed dial and autodial locations at a telephone.

All class of service (COS) programming is performed from station 10 or 12. Any station and console combination will function in this mode and provide visual feedback with the LED associated with the programming button. By employing an LCD speakerphone, however, the programmer will have the benefit of display prompts and verifications to simplify and clarify the programming procedures. Class of service programming access is as follows:

Flexible Station And Line Class Of Service Control

The extension number of a station and all other programmable attributes that are initially assigned to a particular station port and the line, along with all programmable line attributes that are initially

connected to a particular line port can be re-assigned to a different port through programming action. This feature allows adds, moves, and changes without

re-locating the station and line wiring. A programmer can use line and station class of service programming are used to reassign stations and lines.

Class Of Service Programming

A programmer can use an asynchronous, serial data terminal with an

service programming through menu-driven procedures. VDT programming provides a menu-driven approach to programming that is

discussed in Chapter 4.

Class Of Service Program Printout

The common equipment provides serial data ports that the installer can use to interface an RS-232 compatible, asynchronous serial data printer to the system. The connected.printer will provide a printout of class of service and toll restriction records. The programmer can use the data printer service class of service programming procedure to specify the nature and extent of each requested printout. He or she can use the system class of service programming to specify the bit-length and baud rate of the data.

Default Functional Program

At initial power-up, the system sets the operating

features to a specific group of operating conditions

(default conditions). The default conditions provide a complete operating system for normal use. The installer can leave the system defaulted or reprogram as desired. After a programmer has reprogrammed a

system, he or she can re-default it by using the system, line, and station class of service programming or use a master clear to default the entire system and erase all stored programmable button information.

Remote Programming And Administration

Both remote class of service programming and the transmission of SMDR data for printing are available through serial data ports. The system supports X-on

X-off terminal control codes as well as a DTR signal for handshaking. The system data communications

operates per the popular XMODEM protocol. The

database can be uploaded or downloaded, error free, from or to a remote computer that is running software that supports the XMODEM protocol. The two serial

data ports allow VDT programming (either local or

remote) to be conducted through one port at the same time that the other port is being used to send SMDR

data for printing. VDT programming of the system is

menu driven.

Direct Department Calling With

Departmental Call Distribution (DCD)

The system enhances direct department calling with departmental call distribution (DCD) and provides a means by which outside lines can be assigned to one of four different departments. Calls received on

department lines and calls that are transferred to a department from within the system search for an idle station in that department. The system distributes department calls evenly throughout the department stations for answering with individual stations having the ability to be taken out of service as necessary.

The system places calls received on department lines

and calls that are transferred to a department from

within the system in a queue for servicing.

new calls, transferred calls, and held calls a time stamp so that they will be serviced in the order of their arrival.

The system allows up to four departments and allows up to 16 stations (plus one overflow station) in each one. The programmer can assign a station to more than one-department, if desired.. Since the programmer can assign a station to more than one department, she or he can add the attendant station to serve as the overflow station for all departments if desired. The programmer can assign separate pilot numbers (extension numbers) to each department that

the users can use for making intercom calls or doing call transfers to the department.

The direct department calling feature requires that the programmer assign lines and stations to a department.

It does not require that he or she assign department lines to appear at buttons on department stations. If a

site requires that a particular department line must appear at a particular department station, the programmer can assign it; however, the programmer must ensure that neither direct nor delayed ringing is enabled for that line at that station.

An incoming call searches for the first station availabte

to answer a call. If all stations in a department are

busy or ring with no answer (RNA call), the call will go

to the overflow station in that department (if one has

been programmed). If there is no overflow station programmed, the call continues to try the department

stations until it is answered or dropped by the caller. The caller continues to receive ringback tone until the call is answered. The overflow station can service the call or transfer it back to the department using the

department pilot number. When the call is transferred

back to the department by an overflow station, it will

not return to the overflow station until that station is

Subsequent calls to a department on a particular line

always try the next station in the department from

whichever station serviced the last call on that line. To understand this, assume a department with

stations 15, 16, and 12 assigned as department

members

1,2,

and 3. Further assume lines

1,2,

and 3 are programmed to ring in this department. To create a randomizing effect, the system tracks for each line which department member (1,2, or 3)

serviced it last. When the next call arrives on line

for instance, the system makes a search for the next

idle department member after the last one that serviced a call on line 1. Since there are several lines assigned to the department and conversation times and wrap-up times vary, a natural random distribution of calls on lines

1,2,

and 3 at stations 15, 16, and 12

will occur. Further, since the system is keeping track

It should be noted that the departments formed for use

with this direct department calling feature are different from those departments used in SMDA reporting. Assign department transfer recall time (unanswered call transfer recall time feature) using the system class of service programming. Assign lines for direct

department calling using the line class of service

programming. Assign department stations, access codes to departments (flexible numbering feature),

and busy/RNA timeout (call forward - busy feature)

using the station class of service programming.

Departmental Calling Distribution (DCD) Report

The attendant station can request a Departmental

Calling Distribution (DCD) report that provides a compilation of department call activity. The statistics that are reported are based on the department assignments that are active at the time of the report and are extracted from the SMDR records collected by the system. For a report to be generated, a

department must exist. All calls that are included in the DCD report, must meet the following conditions

before they are reported as department calls:

on a per line basis of the servicing stations as

department members instead of station numbers, the programmer could rearrange the department list

without having any effect on call distribution. As the programmer adds more stations to a department, the randomizing effect improves.

A DCD report consists of the following columns of

information:

Since the RNA time of a station is a programmable

feature, department stations can be set to have a

short RNA time to allow a call to search rapidly through a department for an answer.

When an outside or transferred call is ringing at a department station, the station user can press the

pre-programmed Do Not Disturb (DND) button to place the station in an off-duty condition. While

off-duty, all outside and transferred calls skip to the next department station. This off-duty condition remains set until the DND button is pressed again to place the station back in service. When the overflow station is set to DND, all incoming and transferred calls will return to the department queue.

A department station can also be taken out of service and placed in a wrap-up mode to provide the user time for doing such things as follow-up paperwork. While a station is in a wrap-up mode, all outside and transferred calls skip to the next department station.

Direct Inward Station Dialing (DISD)

The DISD feature allows an external party to call an

intercom station directly without assistance by the attendant. The DISD call must be received on a line which has been specially programmed to allow this feature. Any line can be programmed to be a DISD

line for both the normal mode of operation and the night transfer (of ringing) mode of operation.

The number of rings which occurs on a DISD line

before it is answered is programmable. By setting a large number of rings, time is allowed for a call to be serviced in a regular manner by stations that have a line appearance for the DISD line. Setting the number of rings to 0 disables the line for DISD use. If a line is

to be dedicated for DISD use, it is a good practice to

set it for one ring. The amount of time allowed for an

extension number to be dialed is programmable and a

DISD assist station can be programmed to answer

calls that are not completed during this dial time limit. When a DISD line is called, it rings for a programmed number of rings. If the call is not answered in a normal manner by a station with the line appearance during this time, the system answers it and presents a

DISD dial tone to the caller. The system then waits for

an extension number to be dialed from the calling telephone. Only one DISD line is serviced at a time; therefore, an incoming call could ring for more than the programmed number of rings if a DISD call is being serviced when a second DISD call is received.

When a valid extension number is dialed, a confirmation tone is sounded, the system attempts a transfer, and thecalled station rings if it is idle. If a called station does not answer within the transfer

recall timeout period, the call is returned to DISD dial tone. If the called station has the call forward feature set, the forwarded station rings. If a called station is busy, the call is placed on hold and camped-on at the busy station. If the camp-on is not answered within the transfer recall timeout period, a busy tone is given followed by DISD dial tone. The system will return the caller to DISD dial tone two additional times and then drop the line (a total of three attempts are made).

NOTE: If the busy called station is part of a hunt

group, the DISD call is routed to an idle station in the

hunt group. If no idle stations are found, the call is

camped-on at the dialed station.

followed in the case of a ring-no-answer (RNA).

If an invalid extension number is dialed, an error tone

is sounded before the DISD dial tone is returned. If a

mistake in dialing is made, the caller can dial a

new DISD dial tone. The system will return the caller to DISD dial tone two additional times and then drop the line. If extension number dialing is not completed

within the programmed dial time limit, the call is routed

to the DISD assist station if one is programmed;

otherwise, the line is dropped. If the assist station is

busy (call will camp-on at the assist station) or if the

assist station does not answer before the transfer

recall timeout period, the system will return the caller to DISD dial tone. If extension number dialing is not completed within the dial time limit this time, the line is dropped.

The installer should connect a music source to the

system so the music can provide a reassurance to the

caller during a camp-on situation when the DISD feature is being used.

Description Of System Features

IMl66-107

Direct Station Call Hold (Station Park)

This feature allows a station user to park a call at a specific station where it will be held without ringing. A

feature code plus a station extension number can be

dialed over the intercom line to park the call or a programmable button can be programmed to provide a “directed hold” to a specific station. The parked call is picked up by directed station by dialing a feature code.

It can be picked up at any station through the use of

the call pickup feature. No class of service is required.

Also refer to the discussions titled Call Pick-Up

Directed and Call Park.

Direct Station Selection (DSS)

Programmable

Refer to the discussion titled Programmable DSSBLF.

Distinctive Ringing

Refer to the discussion titled Ringing.

Do Not Disturb

Any station can be set to a do-not-disturb mode

using the designated DND programmable button and associated indicator (indicator will light when DND is active). While in the DND mode, the station will not

ring on any incoming call nor will it accept an intercom 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

unless the override feature is enabled. The DND

feature is used with the departmental calling feature to

provide a station wrap-up mode and a station off-duty mode.

Do Not Disturb Inhibit

The system can be programmed to inhibit any station from entering the DND mode. System class of service

programming is used to program this feature.

Do Not Disturb Override

Stations can be provided with DND override capability which will allow them to call a station that is set in the

DND mode. The Executive/Attendant Override feature

must also be active for DND override feature to function. Station class of service programming is used

to assign this feature.

(DND)

Dual Console Support

Refer to the discussion titled Console Support.

Dual Intercom

Refer to the discussion titled Intercom.

Dynamic Line Buttons

Through class of service programming, the programmer can arrange certain idle line buttons to serve as dynamic line buttons. This feature allows the system to temporarily assign a line to a station that

normally does not have the line assigned to it, and

have that line appear on a dynamic line button. While the call is appearing on the dynamic line button (LED on), any normal call handling operations can be performed. Station class of service programming allows certain buttons to be programmed as dynamic line buttons

End-To-End Signalling On Intercom

After an intercom call has been established with an

ATI-D port, the system can continue to send dialing

signals (DTMF tones) through the intercom path. This

feature can be performed from every station in the

system, and is used by peripherals such as voice mail

equipment.

End-To-End Signalling On Lines

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 system.

Refer to the discussion titled Hold.

This feature allows the user of a station, upon encountering a busy signal at another station, to dial a code that will override the busy signal of a call, sound a warning tone, and allow access to the existing conversation. This feature is enabled through station class of service programming.

Refer to the discussion titled Paging.

A large array of individual features can be disabled

system-wide to provide a basic telephone system. A basic telephone system is useful for installation environments where a large proportion of the stations are accessible to unauthorized users thus subject to

tampering or for environments where station users

must be limited as to the variety of features allowed to them. Features are disabled by system class of service. Once disabled, they can enabled by turning on all features at once using the system default programming.
