Description

Use Account Code Entry to enter account codes (developed by accounting or administrative personnel) for outside calls, both incoming and outgoing. These codes appear on Station Message Detailed Recording (SMDR) reports, along with other call information, and are used for billing or cost accounting to identify outgoing calls with a project, client, or department. You can enter an account code before or during a call or not at all. You can also change, correct, or cancel an account code while the call is in progress.

Forced Account Code Entry is similar, but affects only outgoing calls and requires a caller to enter an account code before placing an outside call. You can change or correct an account code while a call is in progress, but you cannot cancel it.

24 Abbreviated Ring

Feature Reference

To enter, change, or correct an account code during a call, activate the feature and enter the account code. Only the person who enters the account code hears the tones generated by dialing the account code number. To cancel an account code (when permitted), activate the feature and exit without entering a code.

With Forced Account Code Entry, if you try to make an outside call without entering an account code, the following occurs:

■

If you select an outside line on an SA button (by dialing a dial-out code) or on an ICOM button (by dialing the Idle Line Access code) without entering an account code, the call is blocked. Depending on the type of telephone used, this may be indicated by the programmed Account Code Entry button flashing, the SA button going to the off/idle state, or an intercept tone.

■

If you try to make an outside call on a personal line or Pool button without entering an account code, there is no dial tone.

Considerations and Constraints

If SMDR is set to record outgoing calls only, you cannot enter an account code for incoming calls.

The system does not validate account codes; it only checks for the number of characters entered (maximum of 16) and for completion (dialing

#

or pressing a

programmed Account Code Entry button).

Account codes can be no more than 16 characters in length, and only the digits 0–9 and the character

*

can be used.

With Forced Account Code Entry, you can enter account codes for incoming calls and for incoming calls added to a conference call by using the Account Code Entry feature. You do not have to enter account codes in these situations. (Outgoing calls added to a conference must have an account code.)

You cannot change an account code entered from another extension.

An incoming caller cannot hear tones as account codes are entered during a call.

An Account Code Entry button only activates and completes the account code entry. It does not automatically enter an account code. A separate outside Auto Dial button can be programmed with an account code number.

Account Code Entry/Forced Account Code Entry

25

Feature Reference

Prior to Release 2.1, users at extensions programmed with Forced Account Code Entry need to enter an account code to use Loudspeaker Paging. In Release 2.1 and later, users at extensions programmed with Forced Account Code Entry do not need to enter an account code to use Loudspeaker Paging.

Description

Used in conjunction with calling restrictions (outward and toll), an Allowed List is a list of numbers that the caller is allowed to dial, despite restrictions. For example, an Allowed List assigned to an outward-restricted extension can allow calls to specific local numbers, such as emergency (911) or toll numbers. For toll-restricted extensions, an assigned Allowed List can allow calls to specific area codes and/or exchanges needed for daily tasks.

A Disallowed List is a list of local or toll numbers that the telephone user is not allowed to dial, even if the extension is otherwise unrestricted. Disallowed Lists can be used as an alternative to or in conjunction with calling restrictions.

Both Allowed Lists and Disallowed Lists are assigned to individual extensions.

Allowed and Disallowed Lists can also be used in conjunction with Remote Access to restrict calls made through the system from remote locations. In this case, Allowed and Disallowed Lists can be assigned to either specific remote access barrier codes or (if barrier codes are not used) to specific types of trunks (all tie/DID and all non-tie/non-DID trunks).

When an Allowed List is assigned to a barrier code or remote access trunks, the remote access user using that code can dial specific numbers included in the list. When a Disallowed List is assigned to a barrier code, the remote access user using that code cannot reach the specific numbers included in the list.

If barrier codes are not used for remote access, then Allowed and Disallowed Lists for remote access users can be assigned to all tie/DID trunks and all non-tie/non-DID trunks.

A Night Service Allowed List can be programmed with up to 10 numbers that anyone can dial without having to enter a Night Service password. For additional information, see “Night Service.”

34 Allowed/Disallowed Lists

Feature Reference

Star Codes and Allowed/Disallowed Lists

In some instances, after dialing a three digit number) the central office provides a second dial tone as a prompt for the dialer to enter more digits. In most cases this second dial tone is immediate. However, in cases when the second dial tone is delayed, calls can be misrouted or dishonest users might be able to circumvent communications system dialing restrictions.

In Release 3.1 and later, the system administrator can enter the star digit (*) in Allowed List and Disallowed List entries. The communications system can be programmed with a delay period (Second Dial Tone Timer) during which no dialing is allowed (in order to let the central office dial tone return). If dialing is attempted, the call is treated as though it had violated calling restrictions and is not completed.

The star codes that are recognized by the system are as follows:

■

2-digit codes: *(00-19,40-99)

■

3-digit codes: *(200-399)

star code

(a star digit followed by a two or

Restrictions are reset after leading star codes. This means that any star codes that are not included in an Allowed or Disallowed List are not considered. The digits that follow the star code are then compared again to the lists. If a caller dials *67280, Allowed/Disallowed Lists acts as if 280 were dialed. Star codes do not need to be placed into an Allowed or Disallowed List in this case to restrict calls to specific exchanges or Area Codes.

The programmed delay is also activated when the rotary telephone equivalent of star codes is dialed (for example, 1170). Multiple leading star codes (such as *67*70) are also handled by the system, since the dialed number is checked against Allowed and Disallowed Lists after each star code is detected.

Following are examples of how to set table entries to achieve specific results:

■

Disallow calls preceded by *67, but allow all other calls: Enter *67 as a Disallowed List entry.

■

Disallow calls preceded by all star codes, but allow all other calls: Enter * as a Disallowed List entry.

■

Disallow calls preceded by *67, or by *69 but allow all other calls: Enter *67 as a Disallowed List entry and enter *69 as a separate entry.

■

Disallow calls preceded by *67, calls to 900 numbers and 411 but allow all other calls: Enter *67, 900, and 411 as separate Disallowed List entries.

Disallowed Lists and VMI ports

In Release 3.1 and later, ports assigned as Generic VMI or Integrated VMI are assigned the default Disallowed List.

If the system manager wants to allow access to the voice messaging system Outcalling feature, any entries in the default Disallowed List apply to Outcalling calls.

!

Security Alert:

Any changes to the default Disallowed List entries and other restrictions must be considered carefully in order to minimize the potential for toll fraud.

If the system manager changes a port to a non-VMI port, the default Disallowed List is not removed from the port. If the default Disallowed List should be removed, the system manager must remove it from the port thorough system programming.

Considerations and Constraints

A Disallowed List takes precedence over an Allowed List. If a telephone number is on both an Allowed List and a Disallowed List assigned to an individual extension, the caller cannot complete a call to that number.

36 Allowed/Disallowed Lists

Feature Reference

If a zero (0) is programmed as the first digit of an Allowed List entry, any toll restriction assigned to an extension is removed for calls placed through a toll operator.

Individual Allowed and Disallowed Lists are numbered 0 through 7. Within each list, there are 10 entries numbered 0 through 9.

The Pause character (entered by pressing the Hold button) can be used as a wild card character in Disallowed Lists, for example, to indicate that calls to a given exchange are restricted in every area code. (The Pause character is shown on the planning form as Allowed List entries. The Pause character does not act as a wild card for the character.

When used in conjunction with Remote Access, Allowed and Disallowed Lists are assigned to specific barrier codes or to types of trunks: all tie/DID trunks, or all non-tie/DID trunks. Allowed and Disallowed Lists cannot be assigned to trunks on an individual basis.

When used with Automatic Route Selection (ARS), Allowed and Disallowed Lists are not applied until the caller dials the ARS code and a pool is selected.

An authorization code can range from 2 to 11 characters and must be unique across the system. However, more than one user can use an authorization code simultaneously. Authorization codes do not all have to be one length systemwide.

Through system programming, the system manager can assign one authorization code for each telephone extension. One Authorization Code button can be programmed on any MLX or analog multiline telephone (except QCCs). A button with a green LED is suggested.

Entering Authorization Code

While you enter the assigned authorization code, you hear internal dial tone. If you do not enter the code within 15 seconds, the feature is deactivated.

If a telephone with a display is used, the display shows asterisks instead of the entered digits.

To complete entry of the authorization code, either press a programmed Authorization Code button again, or dial a # to signify the end of the code. If the entered authorization code matches an assigned code, you continue to hear internal dial tone and can start dialing the telephone number.

The green LED associated with a programmed Authorization Code button becomes steady to indicate that an authorization code has been successfully entered. The LED remains steady as long as the Authorization Code feature remains active.

If the authorization code is not valid, you hear an error tone (a high tone followed by a low tone). The green LED associated with a programmed Authorization Code button goes off to indicate that the Authorization Code feature is not active. An MLX display telephone shows the message

Deactivation of Authorization Code

Each entry of an authorization code is good for only one phone call. After completing a call, the current extension loses “home extension” privileges. It also loses privileges for subsequent calls after putting a call on Hold, or after initiating Recall, Headset Hang Up, or Park features. If a far-end disconnect is not received from the central office, you must go on-hook or select another outside line to deactivate the Authorization Code feature.

After the feature is deactivated, the green light next to the Authorization Code button (if present) turns off.

Description

Use Auto Dial buttons for one-touch dialing of frequently called telephone numbers. Two types of Auto Dial buttons can be programmed:

■

Inside Auto Dial. This button automatically dials any extension or group extension in the system such as a co-worker, calling group, fax machine, or voice mail system. An operator can also program inside Auto Dial buttons for park zone extension numbers.

When an inside Auto Dial button is programmed, the user can see the status of the extension associated with the button; the green LED next to the button is on when a person at the extension is on a call, when Do Not Disturb is on, or when the extension is forced idle for centralized telephone programming or system programming.

■

Outside Auto Dial. This button automatically dials frequently called telephone numbers, as well as account codes, long distance company access codes, bank access codes, or emergency contact numbers.

Considerations and Constraints

When an Auto Dial button is used to make a call, the green LED next to the button does not turn on.

Only company extension numbers should be programmed on inside Auto Dial buttons. Account codes, long-distance company access codes, and outside telephone numbers should be programmed on outside Auto Dial buttons.

Auto Dial

49

Feature Reference

If a user tries to program an incomplete extension number on an inside Auto Dial button, the system provides an error tone and the button remains as programmed.

If numbers are dialed incorrectly by outside Auto Dial, it is possible that the digits are being dialed before a central office dial tone is received. In this case, a Pause should be programmed as the first digit of the dialed number in Key mode and the next digit (after the dial-out code) of the dialed number in Hybrid/PBX mode.

To enter special characters in a telephone number programmed on an outside Auto Dial button, use Conf for the Flash character, Drop for the Stop character, and Hold for the Pause character. See Table 1. These special characters can not be programmed on inside Auto Dial buttons.

If the Stop character is the last character in the number, it has no effect on how the Auto Dial button functions.

In Release 2.1 and later, when a call is forwarded to a multiline telephone that has an inside Auto Dial button programmed for the forwarding telephone, the green light next to the Auto Dial button does not flash.

Feature Reference

Ringing/Idle Line Preference

Ringing/Idle Line Preference is a single option that controls two aspects of a telephone’s behavior: selection of a line when a call arrives, and selection of a line when a user goes off hook. Turn this option on or off for each extension through extension programming or centralized telephone programming, using the display or programming codes. When Ringing/Idle Line Preference is on for an extension, the system selects a line button automatically, as follows:

■

Ringing Line Preference selects a ringing outside line, SA or ICOM button, or Cover button; that is, the red LED turns on next to the button with the ringing call. If you lift the handset or press the Speaker button, you are automatically connected to the ringing call.

The button must be programmed for Immediate Ring or Delay Ring. The red LED next to a button programmed for No Ring does not turn on unless you press that button to select that line. See “Ringing Options” for additional information.

■

Idle Line Preference selects an available outside line, SA, or ICOM button for an outgoing call. If you lift the handset or press the Speaker button when no call is ringing, the red LED turns on next to an available line button, and you are automatically connected to that line.

On is the factory-setting for Ringing/Idle Line Preference for all extensions. If Ringing/Idle Line Preference is turned off for an extension, no line button at that extension is ever selected automatically. The red LED is never on until you press the line button with a ringing call (flashing green LED) or an available line button (green LED off) to make a call.

Automatic Line Selection

When Ringing/Idle Line Preference is turned on at an extension, the system uses the programmed ALS sequence to select an idle SA or ICOM button or outside line button for originating a call. When you lift the handset or press the Speaker button without selecting a line button, the red LED next to the first button in the programmed sequence turns on and you are connected to that line. If the first line is busy, the system selects the second button in the sequence, and so on.

For example, if you normally make toll calls, a WATS line assigned to the extension can be programmed as the first line in the sequence, and local lines as the second, third, and so on. When you lift the handset or press the Speaker button, the WATS line, if available, is selected automatically.

On a multiline telephone you can override ALS by pressing the preferred line button before you lift the handset or press Speaker (the red LED next to the selected button turns on).

56 Automatic Line Selection and Ringing/Idle Line Preference

Up to eight line buttons (except on single-line telephones) can be programmed in the ALS sequence for an extension, either through centralized telephone programming or through extension programming, using programming codes only.

Feature Reference

Considerations and Constraints

Outside line buttons and SA or ICOM buttons can be included in the ALS sequence. However, inside and outside lines should not be interleaved. A typical sequence would consist of all desired SA or ICOM buttons, followed by all desired outside line buttons.

When personal line or Pool buttons are assigned to a single-line telephone or other tip/ring device (such as a fax machine) connected to an 012 module, an 016 module, or a Multi-Function Module (MFM), the buttons are automatically added to the ALS sequence.

When a user or system manager enters ALS programming, the system clears the current ALS sequence for the extension. If the person programming the extension exits without selecting any buttons, the extension has no ALS sequence. The effect is as if Idle Line Preference is turned off: no line is selected automatically when the user lifts the handset to place a call.

Automatic Maintenance Busy

At a Glance

Users Affected Telephone users, operators Reports Affected System Information Mode Hybrid/PBX System Programming

Description

When Automatic Maintenance Busy is enabled, a malfunctioning loop-start, ground-start, or tie trunk is automatically put in a maintenance-busy state, preventing outside calls from being made on that trunk. Incoming calls are never blocked.

In general, the two reasons for putting an outside trunk in a maintenance-busy state are as follows:

■

Faulty or delayed signaling between the system and the central office. To avoid busying out trunks because of slow telephone company central office responses rather than faulty trunks, four consecutive occurrences of faulty or delayed signaling are required before the trunk is put in maintenance-busy state.

■

Central office failure to disconnect (make the trunk available for use) after the user hangs up. The trunk is put in maintenance-busy state after two occurrences of a failure to disconnect.

System→MaintenBusy

When a trunk is put in maintenance-busy state, an error is recorded on the internal error log. The log indicates which type of error occurred: faulty or delayed signaling, or central office failure to disconnect.

Once a trunk is in maintenance-busy state, the three ways to clear the condition and put the trunk back into service are as follows:

■

Periodic testing of the trunk by the system’s internal maintenance software to verify proper functioning

■

Manual clearing of the error from the error log

■

Manual seizure of the trunk at the operator console or through maintenance dial codes

Automatic Maintenance Busy

61

Feature Reference

Considerations and Constraints

Incoming calls are received and processed normally on trunks in a maintenance-busy state.

Direct Inward Dialing (DID) trunks (Hybrid/PBX mode only) are not affected by Automatic Maintenance Busy, because these trunks can only receive calls and are not pooled.

100D (DS1) modules configured as ground-start, loop-start, or tie trunks are monitored and maintained by Automatic Maintenance Busy.

No more than 50 percent of the trunks in a trunk pool can be placed in maintenance-busy state at one time, disconnect a trunk (preventing its use) or when an entire trunk module is manually taken out of service (called a In the case of the 100D module, any failure in the DS1 link causes the module to generate a loss-of-service alarm, and the entire module is taken out of service.

Feature Reference

Description

Automatic Route Selection (ARS) is available only in Hybrid/PBX mode. ARS allows outgoing calls to be dynamically routed over selected trunk facilities after dialing an ARS access code (usually a least expensive route for each call.

9

). This enables the system to select the

Programmable lists, called

tables

, indicate the desired routes (line/trunk facilities) for specified area codes and/or exchanges. There is a different ARS table for each type of call (local, toll, special number, etc.). The tables are chosen according to the telephone number digits that are dialed by the user. Each ARS table has a particular trunk pool that it routes calls to.

A table contains some or all of the following types of information:

■

Table Type. Indicates how to interpret the information in the table. Table types are Area Code, Local Exchange, 6-Digit, 1 + 7, Dial 0, Special Numbers (N11), Default Toll, and Default Local. Details for each table type are discussed later in this section.

■

Digit Strings. 3-digit entries in the table, typically area codes or exchanges. Dialed digits are compared to the stored digits. A match should occur in only one table and cause selection of the routes specified in that table.

■

Subpattern. An array of up to six routes. There are two subpatterns for all tables except the Special Numbers (N11) and Dial 0 tables. The subpattern selected depends on the time of day that the call is made, and the start time associated with each subpattern. (The start time for Subpattern A is specified as the stop time for Subpattern B.)

The Special Numbers (N11) Table always uses the main pool and thus has neither subpatterns nor routes. The Dial 0 Table has no subpatterns and only one route.

■

Routes. A structure that defines possible trunks to be used in a preferred order, usually based on lowest cost and the telephone user’s privilege level or Facility Restriction Level (FRL). Routes cannot be programmed for the Special Numbers (N11) Table. A route contains the following types of information.

Pool. A group of trunks that are to be used for this route. A pool must be programmed before any other route information.

Facility Restriction Level (FRL). A value from 0 to 6 associated with the route. (0 is the least restrictive and 6 is the most restrictive value for routes.) In order to use the route, a caller (according to extension or remote access barrier code/trunk) must have an FRL that is equal to or greater than the FRL of a route.

Automatic Route Selection

65

Feature Reference

ARS allows up to 16 programmable tables, each of which may contain one of the following types of information:

■

Absorbed Digits. The number (0 to 11) of user-dialed digits that ARS absorbs (does

not

dial out) on this route. Digits are absorbed starting

with the first user-dialed digit after any leading star codes. System-Prefixed Digits. A string of up to 20 digits (0–9, *, and

Pause) that ARS dials out on this route

before

dialing any remaining

user-dialed digits but after dialing any user-dialed leading star codes.

Area Code Tables. These tables are lists of 3-digit area codes. Area code tables are useful if just one type of trunk (for example, a regional WATS trunk) is used for all calls to each area code on the list.

Local Exchange Tables. These tables list 3-digit exchanges within the local area code. They can be used to route calls over in-state WATS lines.

6-Digit Tables. If the cost of calls to another area code varies according to the exchange, this table can be used to route calls on different trunk pools, depending on both the area code and the exchange.

In the 6-digit tables, an area code is the first entry. The remaining 99 entries are exchanges within the area code. The system scans the first 6 digits of the user-dialed number (area code and exchange) to route the call.

■

1 + 7 Tables. In some areas, callers must dial a 1 and a 7-digit number to call certain exchanges, even though the call is within the local area code. A 1 + 7 table contains a list of exchanges within the local area code that require dialing a 1 but

not

an area code before the 7 digits.

In addition to the fully programmable tables, ARS has four factory-set tables:

■

Dial 0 Table. This factory-set table routes calls to numbers that start with

0. The international dialing code, 011, is treated as a special case and can be put into a programmable table. If 011 is not specified in a programmable table, international calls are routed through the Dial 0 Table. Programming of this table is limited to a single pool, its FRL, and system-prefixed digits.

■

Special Number (N11) Table. This factory-set table routes calls to the special numbers 411, 611, 811, and 911. The main pool is always used. This table is not programmable.

66 Automatic Route Selection

Feature Reference

■

The system can have up to 20 tables, 16 of which are fully programmable. The Dial 0, Special Number (N11), Default Toll, and Default Local tables are factory set and allow limited programming.

Each table (where appropriate) can have two subpatterns (A and B) with an associated start time. (The start time for Subpattern A is specified as the stop time for Subpattern B.) One or the other subpattern is selected based on the time of day and the subpattern start time. (If both subpatterns have 00:00 start time, Subpattern A is selected.) Each subpattern can contain up to six routes, listed in order of preference or cost effectiveness.

Default Toll Table. This factory-set table routes toll calls to numbers that do not match entries in any of the area code, 6-digit, or 1 + 7 digits. This table has two subpatterns of up to six routes each, but neither absorbed digits nor system-prefixed digits are used.

Default Local Table. This factory-set table routes local calls to numbers that do not match entries in the local exchange tables. This table has two subpatterns of up to six routes each, but neither absorbed digits nor system-prefixed digits are used. In Release 3.1 and later, routes assigned to the default local table are factory set with a Facility Restriction Level of 2.

In addition, each route has a Facility Restriction Level (FRL) associated with it. The FRL is used to refine the route selection process further. Each extension or remote access barrier code or remote access is assigned an FRL from 0 through 6. Each route is also assigned an FRL from 0 through 6. For extensions, 0 is the most restrictive and 6 is the least restrictive level. For line/trunks, 6 is the most restrictive and 0 is the least restrictive level. An extension can use a route only if its FRL is greater than or equal to the route’s FRL.

Other digits or special characters may be required so the system can route a call on a particular trunk pool. For example, some companies use an alternate toll call carrier that requires dialing the telephone number with Pauses and access codes. Each ARS route may have up to 20 characters that are automatically prefixed when the user dials a number. The allowed characters are the digits 0 through 9,

*

, and Pause.

ARS also provides an absorb (ignore) digit capability for each route. For example, if the central office does not require 1 before an area code, the system can be programmed to ignore that first digit. Up to 11 characters can be automatically absorbed when the user dials a number. For 10-digit toll calls, the prefix 1

must

be dialed to indicate to ARS that a toll call is about to be dialed. If the central office does not require the prefix 1 to be dialed for toll calls, the ARS digit absorption feature may be used to eliminate the prefix as the destination is dialed. Initially, all 20 tables are in the list of available tables associated with the call.

Automatic Route Selection

67

Feature Reference

Star Codes and Automatic Route Selection

In some instances, after dialing a star code (a star digit followed by a two or three digit number) the central office provides a second dial tone as a prompt for the dialer to enter more digits. In most cases this second dial tone is immediate. However, in cases when the second dial tone is delayed, calls can be misrouted or dishonest users might be able to circumvent communications system dialing restrictions.

In Release 3.1 and later, Automatic Route Selection processes star codes at the beginning of a dialed number and sends the digits to the central office, before any other digit analysis occurs. Any programmed prepended digits are added after the star code, but before the rest of the telephone number.

Automatic Route Selection is unable to route calls that consist only of a star code with no additional digits (such as *44 for Voice Activated Dialing) because the user has not dialed any digits which the system can use to choose a route.

Dialing calls with star codes using ARS can cause dropped/misrouted calls when prepended digits are used to select facilities other than regular central office lines/trunks. It is recommended that ARS calls containing star codes not be used in configurations where the MERLIN LEGEND Communications System is behind another switch or is used to select non-standard facilities.

For more information on using Allowed and Disallowed Lists to restrict star codes see the Allowed/Disallowed feature.

ARS Restrictions for VMI ports

In Release 3.1 and later, any port programmed as a VMI port is programmed with a Facility Restriction Level (FRL) of 0.

If the system manager wants to allow access to the voice messaging system Outcalling feature, the FRL applies to Outcalling calls.

!

Security Alert:

Any changes to the FRL and other restrictions of these ports must be considered carefully in order to minimize the potential for toll fraud.

If the system manager changes a VMI port to an non-VMI port, the FRL is not reassigned on the port. If the default FRL should be changed, the system manager must change it thorough system programming.

How ARS Works

A user with inside dial tone on an SA button dials the ARS Access Code (usually a

9

) and is connected to ARS. Then the user dials a call. If the telephone is restricted or toll-restricted and the number dialed is not on the Allowed List, or if the number dialed is on the Disallowed List, the user receives a system error tone. Otherwise, ARS compares the number dialed with information in the tables. All tables are available for use at first. Tables are then eliminated from possible use on the call, one by one, until the best table is selected.

Once the table is selected, ARS chooses the appropriate subpattern and checks restrictions, eliminating from consideration any routes with restriction levels higher than the telephone’s. Any remaining eligible routes are scanned from the beginning of the list. The first eligible route that is not busy is selected.

Table Selection

411, 611, 811, 911, or 10xx (Equal Access Code)

If the caller dials one of these N11 or equal access numbers, the call is routed over the main pool, using the factory-set Special Number (N11) Table.

If only a 1 and 7 digits have been dialed and there is one 1+7 Table that matches, it is selected; if more than one table matches, the lowest-numbered table is selected. If there are no 1+7 Tables that match, the Default Toll Table is selected.

If more than 7 digits have been dialed after the 1, the 1+7 Tables are eliminated. The next 3 digits following the 1 are compared to the 3-digit area codes in the Area Code Tables and the first 3 digits of the 6-Digit Tables; any unmatching tables are eliminated. If there are no matches, the Default Toll Table is selected.

If there are matching tables, the next 3 digits are compared to the second through ninety-ninth entry in the remaining 6-Digit Tables. If there is only one match, that 6-Digit Table is used. If there is more than one match the lowest 6-Digit Table is used. If there are no matches and there are no Area Code tables left, the Default Toll Table is selected. If there are no matches and there are Area Code Tables that have not been eliminated, one of the Area Code Tables is chosen. If there is one table left, it is used. If there is more than one table, the lowest one is used.

For a PRI or BRI call, any route that does not match the call type (voice or data) is eliminated from eligibility. Each route may be specified as voice, data, or both.

Automatic Route Selection

73

Feature Reference

NOTE:

If a voice call is queued for callback on a digital trunk pool, it can get stuck in an infinite loop of queuing. The caller hears a continuous stutter tone and cannot get rid of it. To avoid this situation, be certain to correctly program the voice and/or data capabilities of pools of PRI and BRI facilities in the ARS tables.

Any remaining eligible routes are scanned from the beginning of the list. The first eligible route that is not busy is selected. If all eligible routes are busy, the user hears fast busy and can use Callback to queue the call

only.

NOTE:

Emergency numbers must be on an Allowed List to be called from a call-restricted extension.

Considerations and Constraints

(This may result in delays while the user waits for timeout.) To avoid timeout delays, 1 + 7-Digit Dialing Requirements can be programmed as Not Within Area Code, but all exchanges requiring a system-prefixed 1 must be listed in a Local Exchange Table, and the 1 must be specified as a character to be prefixed.

Basic Rate Interface (BRI) 81

Feature Reference

Description

Basic Rate Interface (BRI), like Primary Rate Interface (PRI), is a standard protocol for accessing Integrated Services Digital Network (ISDN) services. By using BRI, the MERLIN LEGEND Communications System can connect with the speed and accuracy of ISDN services. National ISDN-1 (NI-1) BRI service is available for MERLIN LEGEND Communications Systems Release 4.0 and later only.

BRI lines offer the capability of voice, high-speed data, local area network (LAN) interconnection, and video transmission. BRI lines (along with PRI and T1 Switched 56) also allow you to take advantage of the 2B Data feature for desktop video applications. This feature allows one application (such as a desktop video system) to use two B-channels for data transfer rates up to 128 kbps. For more information, see the Digital Data Calls feature.

The following benefits are provided by NI-1 BRI service:

■

Speed. Data calls to outside destinations can be established on the same B-channels used for voice calls if the service allows; Modems and dedicated, conditioned lines/trunks are not needed. By supporting high-speed digital data transmission, BRI provides the capability for video conferencing and Group IV (G4) fax using existing wiring. Each B-channel supports up to 64 kbps throughput.

Improved Toll Restriction. The ways that toll restriction can be bypassed are limited on BRI lines/trunks. Specifically, three types of toll fraud are eliminated with BRI service:

Since dialing is in the form of out-of-band messages that must be generated by the system, a user cannot use a touch-tone generating device, such as a pocket dialer, to send dialed digits directly through the system to the trunk.

Without BRI service, toll restriction can be deceived by dialing digits on a loop-start trunk before the far-end switch applies dial tone. These initial digits may indicate a local call to the system’s toll restriction checking while the subsequent digits, those actually recognized by the far-end switch, may produce a toll call. This is not possible with BRI service, because every dialed digit is screened by the system’s toll restriction check.

A BRI line’s far-end disconnect signal provides a reliable indication when a call ends, and a new call cannot be initiated until the line has been released from the prior call on both ends. This prevents a user waiting off-hook for the restoration of dial tone after a previous call, from placing a second call before toll restriction is reapplied.

■

Reliable Indication of Far-End Disconnect. This prevents an incoming call from being blocked because a trunk has not been released when a call is ended.

Terminology

Lines/Trunks

In this section on BRI, sets or are put into pools. trunks except DS1 (T1 or PRI) and BRI, internal line numbers have a one-to-one correspondence to trunk ports. Since there are 2 transmission channels, or bearer channels (called B-channels) for each BRI connection, two internal line numbers are assigned for each BRI port. B-channels are present for each Digital Subscriber Line (DSL); therefore 16 internal lines are assigned for each module used.

A B-channel is used to carry user information, such as the voice or data content of a call, between the system and the far-end switch.

Multiline Hunt Group

A multiline hunt group can be programmed at the central office to send calls to a number of separate Directory Numbers (DNs) that are grouped together.

A multiline hunt group consists of a group of BRI lines with one main telephone number (Directory Number). When this number is dialed by an outside caller, an incoming call is attempted to one of the BRI lines in the hunt group. If the BRI line is busy, the central office attempts to complete the call to the next available idle line.

The type of switch used by the central office must be known in order to know the available options of Multiline Hunt Group and to set it up correctly.

For the different switches, Multiline Hunt Group has the following capabilities:

■

5ESS. Multiline Hunt is available for voice-only and digital-data-only applications. Multiline Hunt capability is provided under a switch feature called “Series Completion.” Do not use the 5ESS feature named Multiline Hunt Group. For alternate voice and digital data applications, special CO features, for example, Call Forwarding, are also required in the line provisioning. As a result, this configuration may not be supported by some of the RBOCs.

■

DMS-100. Multiline Hunt is available for voice-only, digital-data-only, and alternate voice and digital data applications.

■

EWSD. Multiline Hunt capability is provided under a switch feature called “Series Completion.” However, it is limited to 6 DSLs in a group, and may not be supported by some central offices. Do not use the EWSD feature named Multiline Hunt Group. Multiline Hunt is available for voice-only and digital-data-only applications. Alternate voice and digital data applications are not supported.

Digital Subscriber Line (DSL)

A Digital Subscriber Line provides full-duplex service on a single twisted pair wire (two-wire) at a rate sufficient to support ISDN Basic Rate Access. Digital Subscriber Line (DSL) is used to refer to the facility from the central office that supports BRI service.

Called Party Number (CdPN)

In general, the term was dialed to reach a destination. However, while routing the call, the network can change the Called Party Number to make routing easier. In either case, the network sends the Called Party Number to the system when a call arrives at the system. The called party number is usually displayed on the second page of the MLX display.

Calling Party Number

The Calling Party Number (CPN) provides incoming calling party number information that identifies the originator of a call in the call-handling displays of MLX telephones. If the MERLIN LEGEND Communications System subscribes to this BRI feature, each incoming call to the system over a BRI line can be accompanied by the calling party number or by the billing number of the calling party supplied by the network.

Service Profile Identifier

A Service Profile Identifier (SPID) is a unique identifier used by the central office to associate an ISDN terminal with a Service Profile. It is provided to the user by the central office at subscription time. The system manager must program the SPID for each BRI line to bring the BRI line into service (activate). If dial tone is received, then the correct SPID has been programmed.

Directory Number

In general, a Directory Number is the telephone number that is dialed to reach a destination. When an incoming call arrives on a BRI line, the central office presents the Directory Number as the Called Party Number. Only one call to a particular Directory Number is accepted at any one time. The Directory Number is usually a subset of the Service Profile Identifier The DNs for each BRI are still subsets of the SPIDs. Only the DN for the hunt group are unrelated to the SPIDs.

Clock Synchronization

Clock synchronization is an arrangement in which digital facilities operate from a common clock. Whenever digital signals are transmitted over a communications link, the receiving end must be synchronized with the transmitting end to receive the digital signals without errors.

The system synchronizes itself by extracting the timing signal from the incoming digital stream. If the system has one 100D module, that module provides its own primary synchronization. If the system has at least one 800 NI-BRI module, more than one 100D module, or a combination of 100D modules and 800 NI-BRI modules, then one of the connections provides primary clock synchronization for all 800 NI-BRI and 100D module ports and for the system’s time-division multiplexing (TDM) bus. The primary clock synchronization source must be identified during system programming. The factory setting is the first 100D module in service or the first port in service on the first 800 NI-BRI module in the carrier. This can be changed through system programming.

In the event of a maintenance failure of primary synchronization, backup synchronization can be provided by secondary and tertiary clock synchronization.

In addition, the source of synchronization is factory-set to Loop Clock Reference Source (the clock is synchronized to the external endpoint) or with a 100D module it can be set to Local Clock Reference Source (the clock is free-running). However, this is not recommended for most permanent installations and systems with Primary Rate Interface (PRI). This setting must be made for the primary, secondary, and tertiary synchronization sources.

On a frigid start, the first 100D or BRI port in service is the default primary loop clock source.

If the secondary clock source is incapable of providing the system clock, the tertiary clock source is used. If none of these is capable of providing the system clock, the communications system will select a system clock in the following order:

The communications system searches 800 NI-BRI and 100D modules for a clock source starting from the first module in the system and ending with the last module. The clock is chosen with the following order of preference.

1. Loop clock source on an 800 NI-BRI or 100D module.

2. Local clock source on an 800 NI-BRI or 100D module.

3. Local clock source on the processor module.

Timers and Counters

This option sets the timer and counter thresholds. The factory settings for thresholds are standard and rarely need to be changed. (See “At a Glance” this section for factory settings and valid ranges.) When no response is received from the network before the duration of the timer setting, the communications system takes the appropriate corrective action. The programmable timers and counters are as follows:

■

T200 Timer. Times the minimum time that the link layer waits for an acknowledgment of link establishment, information, or polling supervisory frames sent from the communications system to the network before resending the frames.

■

T203 Timer. Maximum time that the link layer can remain inactive.

T308 Timer. Times the delay in network response when the communications system sends a release message to clear a call.

N200 Counter. Counts the number of times the communications system can transmit a message on a D-channel because no link layer acknowledgment is received from the network. The value for this counter is 3.

Call Processing

An explanation of incoming and outgoing call processing follows.

Incoming Calls

BRI calls can be received on Personal Line or Pool buttons, or by Calling Groups or the QCC Queue. Incoming calls appear to the user like those on other types of lines.

Display Operation

The display provides call-related information about incoming BRI calls delivered over the B-channel, if available. If calling party information is available and the receiving telephone is an MLX telephone, the information is displayed on the telephone. Called party information is usually displayed on the second screen of the MLX display.

Hyphens are inserted between the digits on incoming calls. Examples: 555-1234 for a 7-digit display and 123-555-1234 for a 10-digit display. Any other number of digits appears without hyphens.

A brief description of the display support provided in Release 4.0 follows. Refer to the “

NOTE:

BRI display support for Release 4.0 applies to MLX display sets only. There is no BRI specific display support for analog multiline sets.

”

■

Incoming BRI Calls (Non-Group Calling). When the calling party information is available from the network, the Calling Party Number (CPN) appears on the user’s display. Pressing the More button shows the Called Party Number on the second screen of the display. If the Called Party Number is more than 15 characters in length, the digits at the end are dropped.

■

Group Calling. The MLX display of a calling group member shows the original Called Party Number. Pressing the More button shows the Calling Party Number on the second screen of the display.

■

Transfer Without Consultation. In Release 4.0, pressing the More button on an MLX display telephone that is a transfer destination shows the original Called Party Number.

Outgoing Calls

Outgoing calls on BRI lines can be made by one of three methods:

■

Personal Line. When an idle personal line that represents a BRI line is accessed, the communications system sets up a call to establish a connection to the central office. The status light turns green and dial tone is provided by the central office. As digits are dialed, they are transmitted to and processed by the central office.

88 Basic Rate Interface (BRI)

Feature Reference

■

Pool Button. Like any other type of line/trunk, a BRI line can be accessed by using a Pool button or by using an SA button and dialing a pool access code.

■

Automatic Route Selection. Like any other type of line/trunk, a BRI line can be accessed by using an SA button and dialing the Automatic Route Selection (ARS) access code. ARS processing may modify the dialed number through standard digit deletion and addition processing. ARS can also take advantage of the distinction between Voice and Data calls for routing purposes when making outbound calls over BRI lines. For example, if data is frequently sent to a particular number in another area of the country, ARS can route calls to that number over high-speed data lines.

Considerations and Constraints

Because of limitations with the 391A, 391A1, and 391A2 power supplies, the number of 800 NI-BRI modules plus 100D modules in a single carrier cannot exceed three. If you have more than three modules, you must install the other 800 NI-BRI or 100D modules in an expansion carrier when using these power supplies. The 391A3 power supply eliminates this restriction.

A Directory Number (DN) is considered busy when no extensions are available to answer or cover the call. An extension may be unavailable when: no SA button (aside from Originate Only buttons) is available; Do Not Disturb is activated, or the extension is either being programmed, is in forced idle; the alarm clock is being set. The caller hears a busy tone or the call receives coverage if programmed.

When using BRI, the SMDR format should be set to ISDN format.

An SMDR record is not recorded for any call on a BRI facility that is less than the programmed SMDR Call Length. Usually, the SMDR Call Length is programmed to compensate for connection and ringing time of calls on non-ISDN facilities before they are answered. For systems where the majority of lines are ISDN lines, the call length should be programmed for one (1) second.

Feature Interactions

Account Code Entry Enter an account code at an extension assigned to a BRI line before the

call is made or during the call. If the SMDR feature is not enabled to record incoming calls, the system

does not accept Account Code Entry information for incoming calls.

Call Waiting Call Waiting is provided on BRI lines at extensions so programmed. The

call-waiting tone is not blocked from BRI at an extension if turned on.

Conference Calls on BRI lines can be part of a conference call processed by the

MERLIN LEGEND system, not by the central office (CO). The MERLIN LEGEND system determines the number of active parties on the call.

The MERLIN LEGEND Communications System supports up to five people on a conference: two within the system, two outside the system, and the call originator.

If a MERLIN LEGEND user is part of a conference established by an outside party through the central office Conference feature, the MERLIN LEGEND system may play Music On Hold (if so programmed) when the MERLIN LEGEND user puts the call on hold.

Hold An active call on a BRI line can be placed on hold by using the MERLIN

Recall Recall is not recognized by the central office (CO) on BRI lines.

Therefore, pressing the recall button on a telephone is ignored by the CO.

SMDR The number of a BRI line is shown in the LINE field of the SMDR report.

Call timing begins when the call is answered. Therefore, calls that are not answered do not have an SMDR call record generated.

Description

When an extension is programmed with Call Waiting, a user hears a tone when his or her extension is busy, the user is off hook, and another call is received. For an inside call, the user hears one beep; for an outside call, the user hears two beeps. MLX display telephone users also see The caller hears a special ringback to indicate that the extension is busy and that the call-waiting tone has been sent.

A multiline telephone is considered busy when no SA or ICOM button is available for incoming calls and, if Coverage is programmed, all coverage points are busy.

When the called party frees an SA or ICOM button and there is a call waiting, the caller hears dequeuing tone and the call waiting call appears on the free SA or ICOM button of the called party.

A single-line telephone is considered busy when a call rings on the telephone or the user lifts the handset and, if Coverage is programmed, all coverage points are busy.

Each extension can be programmed with Call Waiting on or off. The default is Call Waiting off.

Call Waiting

Feature Reference

The user hears a call-waiting tone for the following types of calls that ring on an SA or ICOM button:

■

The user does not hear a call-waiting tone for calls received on a personal line unless the business subscribes to call-waiting service from the local telephone company.

The person receiving the call-waiting tone has these options:

■

An inside call A call received on a Direct Inward Dial (DID) trunk A call from a remote access user A call received on an automatic dial-in tie trunk A call transferred to the extension

Ignore the new call and continue with the current call; the caller continues to hear the special ringback.

Complete the current call, hang up, and answer the waiting call when it rings; the caller hears normal ringback.

On a multiline telephone, put the current call on hold and answer the new call using an ICOM Originate Only or SA Originate Only button (if one is available) by using call waiting pickup. Call waiting pickup is activated on an ICOM Originate Only or SA Originate Only button by pressing the Feature button followed by

or by dialing

#87

.

On a single-line telephone, put the current call on hold by pressing and releasing the switchhook or the Flash or Recall button. Dial

#87

to

answer the incoming call.

Considerations and Constraints

A user can have more than one call waiting. If there is more than one call waiting, then a user using call waiting pickup answers the individual calls on a first-come first-served basis.

Call Waiting is not activated if a line button of the appropriate type (such as ICOM or SA) is available to receive a call.

An extension programmed as a fax extension can activate Call Waiting so callers can wait until a fax machine is available. To prevent disruption of a fax message in progress, a call-waiting tone is not sent to a fax extension.

If a person with Call Waiting on is in the process of dialing and receives a call, the touch tones generated while dialing cancel the call-waiting tone. As a result, the person may not be aware that a call is waiting.

Queued Call Consoles

Call Waiting cannot be used on Queued Call Consoles (QCCs); the calls are already queued.

Release a call to a busy extension by selecting Camp-On from the display or by pressing the Release button. If Camp-On is used, the call does not return to the QCC queue until the Camp-On return interval expires. If you press the Release button, the extension being called receives the call-waiting tone (not Camp-On) and the call returns to the QCC queue when the transfer return interval expires.

If the system is programmed for Automatic Extended Call Completion, you must press the Start button to use Camp-On, then dial the extension manually, activate Camp-On, and press Release. If you press a DSS button, the transfer is automatically completed and Camp-On cannot be used.

Other Multiline Telephones

If a multiline telephone does not have an SA Originate Only or ICOM Originate Only button assigned or available, the user cannot pick up the waiting call. To pick up the call, the user presses an available SA Originate Only or ICOM Originate Only button, presses the Feature button and dials

87

.

If either Transfer or Camp-On is used to transfer a call to a busy extension, the call is placed in the call waiting queue and the caller hears the call-waiting tone whether or not the extension has the Call Waiting feature activated.

Single-Line Telephones

If a single-line telephone user presses and releases the Recall or Flash button (if you have a telephone without positive disconnect press and release the switchhook) after picking up a waiting call, the call that was picked up is disconnected and the user is reconnected to the original call. If the user hangs up after picking up a waiting call, the picked-up call is disconnected and Transfer is initiated for the first call; the original call goes on hold and transfer return applies.

Feature Interactions

Basic Rate Interface Call Waiting is provided on BRI lines at extensions so programmed. The

call-waiting tone is not blocked from BRI at an extension if turned on.

Callback

When Automatic Callback is used to queue a call at an extension that has Call Waiting, Callback overrides Call Waiting. The user with Call Waiting does not hear the call-waiting tone, and the call is queued until the extension becomes available.

A user with no available buttons to receive a transferred call hears the call-waiting tone when a co-worker uses Camp-On to transfer a call, even if Call Waiting is not activated.

A call-waiting tone is only heard by the person receiving the call and not by other conference participants. If the conference originator reaches a busy extension, hears the call-waiting special ringback, and tries to add the call to the conference, the system returns a busy tone. To drop the busy tone from the conference, the originator presses the Drop button and then the line button used to call the busy extension.

A call to a sender with Call Waiting activated goes to Individual and/or Group Coverage first. If all coverage points are busy, the sender hears the call-waiting tone.

Changing the status of Coverage On/Off to On after hearing the call-waiting tone does not force the waiting call to coverage receivers but sends subsequent calls to coverage.

Reminder Service SMDR

Call Waiting does not apply to forwarded calls because the system tries the destination extension instead of the forwarding extension. However, if the call is not forwarded for any reason (for example, the trunk selected is an unreliable loop-start trunk), Call Waiting functions normally.

Calls made to a calling group are not eligible for Call Waiting because the call rings into the calling group’s queue. However, Call Waiting can be used for calls to individual members of the calling group.

A person with all calls on hold cannot hear the call-waiting tone. Call Waiting cannot be used for Group Paging calls to busy extensions. A user does not hear a call-waiting tone for calls received on a personal

line unless the business subscribes to a call-waiting service from the local telephone company.

Pickup features cannot be used to answer a waiting call at another extension.

Reminder calls are not eligible for Call Waiting. SMDR does not begin measuring the duration of a call-waiting call until

the call is answered.

An extension is considered busy when all SA or ICOM buttons (excluding SA Originate Only or ICOM Originate Only) are in use. A multiline telephone user can dial the Call Waiting feature code to pick up a waiting call only when an SA Originate Only, or ICOM Originate Only button is available.

A user with no available buttons to receive a transferred call hears the call-waiting tone when a co-worker uses Transfer to transfer a call, even if Call Waiting is not activated.

A call received by using call waiting pickup can be transferred only if an SA or ICOM button to transfer the call on becomes available.

6), the callback request is canceled.

Two types of Callback can be programmed for an extension:

■

With Automatic Callback, when a caller reaches a busy extension or trunk pool, he or she hears the queuing tone (five short beeps) instead of the busy tone. This indicates that the system is putting the call into the callback queue.

With Selective Callback, when the caller reaches a busy extension, he or she must activate Callback while listening to the busy signal. If the caller tries to make a call by using a pool in which all trunks are busy, he or she hears a fast busy signal immediately after dialing the pool dial-out code. After activating Callback, the caller receives dial tone; after all digits are dialed, the caller hears the queuing tone and the call is added to the callback queue.

Automatic. Callback is activated automatically whenever the caller reaches a busy extension or when all trunks in a pool are busy. This is a status feature that is set to On or Off for each extension.

Selective. Callback is activated only when a caller chooses it by dialing a feature code or, on multiline telephones, by pressing a programmed Selective Callback button. On MLX display telephones, a caller can also select the feature from the display.

Considerations and Constraints

With both types of Callback, a caller can either stay on the line until the call is completed or hang up.

■

If the caller stays on the line, the red and green LEDs are on next to the line button used to make the call. When the busy extension or pool is available, the caller hears the out-of-queue tone (three short beeps) and the call is completed automatically.

■

If the caller hangs up, the green LED flashes next to the line button, indicating that the button is being held for the queued call. When the busy extension or pool is available, the caller hears a priority ring (four bursts of ring on an MLX telephone and three bursts of ring on an analog multiline telephone or single-line telephone). If the user does not answer the callback call within the number of rings programmed for the system (1–

For inside and outside calls, the caller hears ringback when the extension is available, but the system does not make the call until the caller picks up.

Callback cannot be used for personal lines assigned to buttons on a telephone. See “Line Request” for additional information. If more than one call is waiting for the same extension or trunk pool, the call that has been queued the longest is connected first.

Callback

97

Feature Reference

When a call is waiting in queue for an extension, no new calls are sent to the extension until after the queued call is completed.

When the queue contains 64 calls (system limit), additional calls sent to the queue result in a busy signal.

No more than 40 dialed digits can be included in a queued call.

In order to use Callback with pools consisting of loop-start trunks, the loop-start trunks must be programmed for reliable disconnect.

Mode Differences

Hybrid/PBX Mode

Callback can be used for busy extensions and for outside calls on pools where all trunks are busy.

Key and Behind Switch Modes

Callback can be used only for busy extensions. Line Request is used for busy outside lines that are assigned to line buttons.

Telephone Differences

Queued Call Consoles

A QCC operator cannot use Callback.

Other Multiline Telephones

On all other multiline telephones, Selective Callback is activated by pressing a programmed Callback button or by pressing the Feature button and dialing On MLX display telephones, Selective Callback is also activated by pressing the Feature button and selecting the feature from the display. If the user is on another call when the system tries to call back, he or she hears an abbreviated ring.

A multiline telephone user can queue more than one call to the same extension.

On a multiline telephone, cancel a callback request by pressing the SA or ICOM button used to make the call, lifting the handset, pressing the Drop button, and pressing the SA or ICOM button again. The red and green LEDs next to the button go off, and the request is canceled.

Single-Line Telephones

A single-line telephone user can make and receive other calls while waiting for the call to be completed. The request remains in the queue until the user who initiated the request is available. Queued calls ring at a single-line telephone in the order which they were queued.

A single-line telephone can queue only one call at a time. If a single-line telephone user who has already queued one call tries to transfer a second call to a busy pool, the transferred caller hears a fast busy tone. The system considers the transfer complete, and the call is not returned to the single-line telephone user who transferred the call.

Cancel a callback request by lifting the handset and dialing to internal dial tone. The system sends a confirmation tone to indicate that the request is canceled.

A single-line telephone user cannot use Callback if another call is on hold. A waiting outside call rings at a single-line telephone before any calls queued for that extension.

Callback for a busy pool because restrictions are based on the specific trunk being used to make the call. When a trunk in the busy pool is available, the system checks for restrictions assigned to the extension. If the extension is restricted, a fast busy signal indicates that the call is not dialed.

Call Waiting When Automatic Callback is used to queue a call at an extension that

has Call Waiting, Callback overrides Call Waiting. The user with Call Waiting does not hear the call-waiting tone, and the call is queued until the extension becomes available.

When Selective Callback is used to queue a call at an extension that has Call Waiting, the user with call waiting hears the call-waiting tone and the call is queued until the extension becomes available.

Conference With Automatic Callback, the call is automatically queued; however, if a

person tries to add the queued call to the conference, the system returns a busy tone. With Selective Callback, the system also returns a busy tone. To drop the busy tone from the conference, the originator presses the Drop button and then the line button used to call the busy extension.

Coverage The sender and all coverage receivers must be busy before a call to the

sender can be queued. The call is sent to coverage before it is put in the callback queue. Once a call is in the callback queue, it is not sent to coverage again. The callback call indicating that a busy extension or pool is available is not eligible for Individual or Group Coverage.

Digital Data Calls Desktop video systems can be programmed for autoqueuing using

Callback. As a line becomes available in the pool, or the busy desktop video system becomes idle, the queued call is made one B-channel at a time. When the second B-channel become available, it is used for the connection as well.

Although desktop video systems can use either on-hook or off-hook queuing, you should only off-hook queuing for 2B Data connections. If you use on-hook queuing (by hitting the End icon) the call will be connected using only one B-channel.

Display When a call is queued by Automatic Callback on multiline telephones or

by Selective Callback on analog multiline telephones, the display shows a feedback message. When an MLX telephone user activates Selective Callback, the display prompts the user to enter the telephone number. When the queued call rings the user’s telephone, the display indicates that it is a returning callback call.

Do Not Disturb Calls to extensions that are using Do Not Disturb are not eligible for

callback queuing. If a callback originator is using Do Not Disturb, the system overrides the feature and the telephone rings when the busy extension or trunk is available.

Extension Status In Hotel mode, an extension in Extension Status 1 or 2 cannot use

Callback to request busy pools.

Forced Account Code Entry

Forward and Follow Me

An account code must be entered before Callback is activated. If not, the user hears a busy tone.

If a user queues a call and then uses Forward, Remote Call Forward, or Follow Me, the call does not ring back at the destination extension or telephone number; the callback call returns only to the forwarding telephone.
