AEC Disconnect
Description
This feature allows th e System to send a disconnect signal of 1 second to an analog device indicating
that the ca lling party has hung up (terminated the call). This feature is useful with a Third-party Voice
Mail or an Answering Machine. By default this fea ture is disabled.
Hardware Requirements
• AEC port
Related Programming
• FF3-0: Loop Disconnect Signal
Considerations
• The 1 second time duration of the disconnect signal is f ixed. (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 freque ntly have special capabilities f or monitoring and programming extensions.
You can reach the assigne d att endant group by dialling the feature access code for Attendant Calls
(usually 0). If an attenda nt phone is avail able but does not answer within a set tim e, the call will move
to the next available attendant phone. If all members of the attendant group are busy for a specif ied
time, the call can be forwarded to othe r extensions or another hunt group. The system allows up to 20
extensions to be included in an atte ndant group.
Hardware Requirements
• N/A
Related Programming
• FF5-0-01: Attendant Hunt Pilot Number
• FF5-0-02: Day 1 Attendant Hunting
• FF5-0-03: Day 2 Attendant Hunting
• FF5-0-03: Night Attendant Hunt
• FF2: Ring Type
Considerations
• The System allows one attendant group for each system mode (D ay 1, Da y 2, and Night).
• An attendant group can contain both real extensions and virtual extensions. If virtua l, 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 45.
22 ICX issued August 1998 ICX-25-700
Section 700 - Operation Chapter 3. System Features
• The pilot number for an attendant group is flexibl e (i.e. , any extensio n number 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 Forwarding - All set, that
phone is temporarily remove d from the attendant group.
• If a member of the attendant group has Call Forwarding - Busy set and the extension 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 Identification) / Dir ect Dial Inward (DDI)
• Direct Inward System Access (DISA)
• Extension calls
• Private network attendant calls
• Call reversion
• Call forwarded to Attendant Hunt Group
Automatic Call Distributor
Description
The System provides an optional Automatic Call Distributor (ACD) for efficient presentation,
handling, and management of incomin g calls to one or more groups of specialized users.
This optional Built-in ACD is conta ined on a single circuit card that is installed in the System. This
“built-in” capability eliminates the need for custom wiring and other installation.
Each specialized use r is known as an ACD agent. Each agent pos ition is eq uipped with a large displ ay
telephone (VB-44225) that provides Liquid Crystal Display (LCD) messages to assist the agent in
handling calls.
The Built-in ACD provides:
• Up to 2 agent groups
• Up to 32 agent IDs per group
• Up to 64 agent IDs per system
• Up to 32 agents
• 1 supervisor ID per group
• Up to 2 supervisor IDs per system
• 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)
• 2-week memor y for MIS rep o rts
• Up to 6 recorded messages (max. 14 sec. per message)
• 1 fixed message up to 5 minutes
Hardware Requirements
• See Section 520 - Built-In ACD Reference Manual.

Automatic Route Selection
Description
When Automatic Route Selection (ARS) is enabled, the system follows a preselected route 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 TRS level for the originating party. (For more information, see “Ringing
Modes” on page 59.)
• 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 an Exchange Line group and any dialled number
modification.
• Route List Selection: A more complex routing that includes up to 5 alternative
levels of route select ion 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, vacat ion days, etc.
• Automatic m odific ation of d ia lled numbers is a vailable . This include s dele ting up t o 24 prefix
digits and adding up to a 10-digit prefix and a 10-digit suffix. The modification of dialled
numbers can include pauses, Dual Tone Multifr equency (DTMF) conversion, itemized code
(extension number) and an author ization code. (Itemized code and authorization are not used
in some areas.)
• Up to 8 authorization codes are available.
• For more information on ARS/TRS (Call Barring), see Appendix A “ARS and TRS (Call
Barring) Operatio n” on page 285.

music or sound source to be used for background music and anothe r music or sound source to be 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 Music on
Hold (if using external MOH) require a sound sourc e.

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 Exchange Line 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 exchange line card (VB-44 510)
• Caller ID circuit card (VB-44513)
Related Programming
• FF2-0: Caller ID
• FF2-0: Caller ID Ring Control
• FF3-0: Call Duration Display
Considerations
• ISDN (PRI - T Point) can get calling party information.
• Caller ID service must be ordered from the local telephone operating company or the
interexchange carr ier.
• Caller ID data is usually sent between the first a nd the second rings of the incoming exchange
line call. The exchange line may be programmed to immediately ring at the station or wait until
after the Caller ID digits are received before ringing at the station. If the exchange line is
programmed to ring immediately, the Caller ID digits will not display until after they are
received and processe d.
• Caller ID numbers may be denied from being sent for some callers (private). Some long distance
carriers may not provide Call er ID data (out of area).
• Caller ID only support the single format (number only). Multiple format (number and name) is
not supported.
Centrex/PBX Compatibility
Description
Centrex/PBX Compatibility allows the System to be connected behind centrex or PBX lines.
The System supports up to 6 access codes for dialling c entrex or a PBX. These access codes allow the
System, System Message Detail Recording (Call Logging) output to exclude the number dialled to
reach a centrex or PBX line.
When connected beh ind a PBX or Centrex, Toll Restriction Service (TRS ( Call Barring)) can be used
to restrict calls.
The System also supports transmission of a flash signal over the centrex or PBX link.
