Chapter 3. System Features Section 700 - Operation

AEC Disconnect

Description

This feature allows the System to send a disconnect signal of 1 second to an analog device indicating that the calling party has hung up (t ermina ted the call). This fea ture is use ful wit h a Third- party Voice Mail or an Answering Machine. By de fault this feature is disabled.

Hardware Requirements

•AEC port

Considerations

• The 1 second time duration of the disconnect signal is fixed. (It cannot be changed.)

Attendant Groups

Description

An attendant phone is often used as a central answering point for other extensions. In addition, attendant phones frequently have special capabilities for monitoring and programming extensions.

You can reach the assigned attendant group by dialling the feature access code for Attendant Calls (usually 0). If an attendant phone is availa ble but does not ans wer wit hin a set t ime, th e cal l will move to the next available attendant phone. If all members of the attendant group are busy for a specified time, the call can be forwarded to other extensions or anot her hun t group. The system allows up to 20 extensions to be included in an attendant group.

Hardware Requirements

•N/A

Considerations

• The System allows one attendant group for each system mode (Day 1, Day 2, and Night).

• An attendant group can contain both real extensions and virtual extensions. If virtual, several phones can be made to ring at the same time.

• Attendant groups can use only Pilot Terminal Hunt Group or Pilot Distributed Hunt Group. For more information, see “Hunting Groups” on page 43.

• The pilot number for an at tendan t group is fl exibl e (i.e., a ny exte nsion n umber can be designa ted as the pilot [not a real extension]).

• If a member of the attendant group has Do-Not-Disturb (DND) or Call Fo rwar di ng - All set, that phone is temporarily removed from the attendant group.

• If a member of the attendant group ha s Cal l For w ar din g - Bus y set and the ext ens ion is busy, the call goes to the next phone in the attendant group.

• If all members are busy for the duration of the busy queuing timer, the call can be forwarded to another hunt group or another extension.

• Attendant groups support the following call types:

• CLI (Called Line Identifi cation) / Direct Dial Inward (DDI)

• Direct Inward System Access (DISA)

• Extension calls

22 ICX (International), issued March/1998 ICX-35-700

Section 700 - Operation Chapter 3. System Features

• Private netw ork attendant calls

• Call reversion

• Call forwarded to Attendant Hunt Group

Automatic Call Distributor

Description

The System provides an op tional Automat ic Call Distributor (ACD) for efficient presentation, handling, and management of incoming calls to one or more groups of specialized users.

This optional Built-in ACD is contained on a single circuit card that is installed in the System. This “built-in” capability eliminates the need for custom wiri ng and other installation.

Each specialized user is kno wn as an ACD agent. Each agent position is equipped with a lar ge displ ay telephone (VB-44225/VB-D411LDSUK) that provides Liquid Crystal Display (LCD) messages to assist the agent in handling calls.

The Built-in ACD provides:

• Up to 3 agent groups (ACD Version 3.0 and higher)

• Up to 2 agent groups (ACD Version below 3.0)

• Up to 32 agent IDs per g roup

• Up to 64 agent IDs per system (ACD Version 2.0 and higher)

• Up to 32 agents

• Up to 6 supervisor IDs per system (ACD Version 3.0 and higher)

• Up to 2 supervisor IDs per system (ACD Version below 3.0)

• Up to 4 voice ports per group

• Up to 4 voice ports per system

• 1 Music-On-Hold (MOH) source (Main System MOH source)

• 1 Management Information System (MIS) Monitor Port (RS-232C)

• Abandoned Call Report counter available with MIS reports (This is not the same as the Abandoned Call Timer added to the Station Message Detail Recorder [SMDR] reports.)

• 2-week memory for MIS reports

• Up to 6 recorded messages (flexible length, max. 96 sec. per system) (ACD Version 3.0 and higher)

• Up to 6 recorded messages (max. 14 sec. per message) (ACD Version below 3.0)

• Zip Tone which automatically answers calls when an agent is using the Headset mode (CPC Version 3.5 and higher)

• Wrap Mode which al lows an agent to complete any paperwork before becoming available to take another call. (CPC Version 3.5 and higher)

Hardware Requirements

•See Section 520 - Built-In ACD Reference Manual.

Considerations

• For more information, see Section 520 - Built-In ACD Reference Manual.

Chapter 3. System Features Section 700 - Operation

Automatic Route Selection

Description

When Automatic Route Selection (ARS) is enabled, the system follows a preselected rout e for calls. Usually the selected routing is the least cost route.

ARS works in conjunction with Toll Restriction Service (TRS) (Call Barring). Calls can be denied based on the programmed TR S (Call Barrin g) level for the originating p arty. (For more information, see “Ringing Modes” on page 57.)

• Three levels of ARS checking are available based on the dialled number following the ARS access code:

• Direct Route Selection: The simplest form of ARS routing that upon ARS entry

(enter 9) directly selects a trunk group and any dialled number modification.

• Route List Selection: A more complex routing that includes up to 5 alternative

levels of route selection and includes TRS (Call Barring) level checking.

• Time List Selection: The most complex routing that determines the appropriate

route list based upon the day and time.

• Forced ARS is available on an Extension Class of Service (COS) basis.

• A special day list provides tailored ARS routing for up to 20 holidays, vacation days, etc.

• Automatic modificati on of dia lled numbers is avai lable. This inclu des de leting up to 24 p refix digits and adding up to a 10-digit prefix and a 10-digit suffix. The modification of dialled numbers can include pauses, Dual Tone Mult ifrequency (DTMF) conversion, itemized code (extension number) and an authorization code. (Itemized code and authorization are not used in some areas.)

• Up to 8 authorization codes are available.

Hardware Requirements

•N/A

Considerations

•N/A

Automatic Trunk to Trunk Transfer

Description

The System can be set to automatically transfer trunk calls out to another trunk without requiring the call to be answered internally. This transfer may be either trunk based or extension based (i.e., call forward outside).

Hardware Requirements

•N/A

Considerations

•N/A

Section 700 - Operation Chapter 3. System Features

Background Music/MOH Separation

Description

Separate inputs are provided for Background Music and Music-on-Hold (MOH). This allows one music or sound source to be used fo r backg round musi c and an other mus ic or s ound sour ce to b e used for music on hold.

A typical advantage of this is playing a pre-recorded promotional tape to held parties (since many may be customers) while providing a selected background music for use in the office.

Hardware Requirements

• Background music requires an SCC card (VB-44181). Both Background Music and MOH (if using external MOH) require a sound source.

Considerations

•N/A

Battery Backup

Description

When backup batteries are installed, the System will continue to operate in the event of a power failure. If using Battery Backup, backup batteries must be installed in each CCU.

A fully loaded system will operate at least 30 minutes on backup batteries.

Hardware Requirements

• Back-up battery unit (VB-44025)

Considerations

• Any device connected to the System but that does not derive its power from the System must have a backup power source to operate. These devices include any System Message Detail Recording (SMDR) (Call Logging) printer (or recorder), fax machine, answering machine, modem, cordless telephone, etc.

Building Block Expansion Capability

Description

The System is designed to support easy expansion. Each CCU in the System supports 96 ports (12 flexible slots) as well as 2 option slots . Up to 6 CCUs ma y be in stall ed in the Sys tem for a to tal of 576 ports.

Up to 2 expansion CCUs may be connected to a base CCU. When a fourth CCU is required, another base CCU is installed. Up to 2 expansion CCUs may be connected to the second base CCU.

This building block approach allows you to easily add equipment when needed without a major interruption in service or a major delay.

Caller ID

Description

(Note: Analog Caller ID is not available in the UK model). A properly equipped ICX supports Caller ID, a service offered by the network telephone service

provider. The trunk sends calling number information to the ICX after the first ring. Users who have display telephones can see Caller ID information as incoming calls ring at their extension and can have access to previous calls via the Caller ID Call Log feature. The Caller ID number is recorded in Call Logging.

Hardware Requirements

• Loop-start trunk card (VB-44510)

• Caller ID circuit card (VB-44513)

Considerations

• ISDN (PRI - T Point) can get calling party information.

• Caller ID service must be ordered from the local telephone operating company or the interexchan ge carrier.

• Caller ID data is usually sent between the first and the second rings of the incoming trunk call. The trunk may be programmed to immediately ring at the station or wa it unt il after the Caller ID digits are received before ringing at the station. If the trunk is programmed to ring immediately, the Caller ID digits will not display until after they are received and processed.

• Caller ID numbers may be denied from be ing sent for some callers ( priva te). Some l ong dist ance carriers may not provide Caller ID data (out of area).

• Caller ID only support the single format (number only). Multiple format (number and name) is not supported.

Caller ID Alpha Tagging (Not Available in USA)

CPC-96, CPC-288, and CPC-576 Version 3.0

Description

If the received Caller ID phone number matches any number in the System Speed Dials (SSD) (SSD000-SSD199), then the associated SSD name can be displayed as the Caller ID information instead of the Caller ID phone number. Alternatively, the Direct Dial Inward (DDI) name may be displayed instead.

Hardware Requirements

• Loop-start trunk card (VB-44510)

• Caller ID circuit card (VB-44513)

Considerations

• The system may be set to display C aller ID in one of two pri orities as follows:

Priority Choice 1

• CID name (future feature)

• Alpha tagging if matched

• DDI name

Priority Choice 2

• DDI name

• CID name (future feature)

• Alpha tagging if matched

• Currently Caller ID only s upport s the s ingle format (number only). Mult iple fo rmat ( number a nd name) is not currently available but is planned as a future feature.

• Caller ID Call Logging only shows the CID number.

Centrex/PBX Compatibility

Description

Centrex/PBX Compatibility allows the System to be connected behind centrex or PBX lines. The System supports up to 6 ac cess c odes fo r dial ling cen trex o r a PBX. Thes e acce ss code s all ow the
