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 (terminated the call). This feature is useful with a Third-party Voice 
Mail or an Answering Machine. By default this feature is disabled.
Hardware Requirements
• AEC port
Related Programming
• FF3-0: Loop Disconnect Signal
Considerations
• The 1 second time duration of the disconnect signal is fixed. (It cannot be changed.)
Attendant Groups
CPC-96, CPC-288, and CPC-576 Version 1.0
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 dialing the feature access code for Attendant Calls 
(usually 0). If an attendant phone is available but does not answer within a set time, the call 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 another hunt group. The system allows up to 20 
extensions to be included in an attendant group.
Hardware Requirements
•N/A

• 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 (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 46. 
						

							Section 700 - Operation Chapter 3. System Features
576-13-700 DBS 576 (USA), Revised 6/11/98  23
• The pilot number for an attendant group is flexible (i.e., any extension number can be designated 
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 removed 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:
•   Direct Inward Dialing (DID) / Dialed Number Identification Service (DNIS) / Direct 
Dial Inward (DDI)
•   Direct Inward System Access (DISA)

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). 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 dialed number following the ARS 
access code:
•  Direct Route Selection: The simplest form of ARS routing that upon ARS entry 
(enter 9) directly selects the trunk group and any dialed number modification.
•  Route List Selection: A more complex routing that includes up to 5 alternative 
levels of route selection and includes TRS 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 modification of dialed numbers is available. This includes deleting up to 24 prefix 
digits and adding up to a 10-digit prefix and a 10-digit suffix. The modification of dialed 
numbers can include pauses, Dual Tone Multifrequency (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.
• For more information on ARS/TRS, see Appendix A “ARS and TRS Operation” on page 291.

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 for background music and another 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 source.

Caller ID
Description
A properly equipped DBS 576 supports Caller ID, a service offered by the network telephone 
service provider. The CO sends calling number information to the DBS 576 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 SMDR.
Hardware Requirements
• Loop-start trunk card (VB-44510) 
• 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 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 wait until 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 being sent for some callers (private). Some long distance 
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.
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 dialing centrex or a PBX. These access codes allow the 
System, System Message Detail Recording (SMDR) output to exclude the number dialed to reach a 
centrex or PBX line.
