Flexible Numbering Plan
Description
The System provides flexible numbering for feature access special numbers and extension numbers.
The dialing plan allows settings for digits dialed at dial tone, digits dialed at ringback tone, digits 
dialed at busy tone, two patterns of feature codes dialed at dial tone, two patterns of feature codes 
dialed at ringback tone, and two patterns of feature codes dialed at busy tone.
Feature access codes can be used when replacing another PBX system with a DBS 576 System. 
Rather than learning the new access codes, the System feature access codes can be changed to match 
the old system. As a result, telephone users are less confused by the change and the requirement for 
retraining is reduced. Two sets of feature access codes are available (one of the two must be assigned 
to the terminal).

Hunting Groups
Description
Hunting allows calls to be automatically transferred among a preselected group of phones. If a phone 
is busy or there is no answer in a set amount of time, the call will hunt to the next phone in the hunt 
group.
A phone assigned to a hunt group is called a member. Up to 20 members can be assigned to a hunt 
group. Up to 12 hunt groups are available per cabinet.
Several methods of station hunting are available. Some methods require use of a pilot number (a 
fictitious extension number) while others start by a direct call to a hunt group member. 
The System supports the following hunting groups:
• Pilot Terminal Hunt Group
• Pilot Distributed Hunt Group
• Switch Back Hunt Group
• Circular Hunt Group
• Next Extension/Hunt Group
Pilot Terminal Hunt Group
Pilot Terminal Hunt Group directs calls to a pilot number. The System begins with the first member 
and hunts through the group for the first available member to receive the call. If no member is 
available (extension is busy or there is no answer for a specified amount of time), the call is queued 
for the first member to become available. You can also set the Queuing Timer to specify how long the 
System will search the initial hunt group before beginning to search the next hunt group or extension.
The main advantage of this type of hunting is that the same hunting order is taken for all calls. This is 
useful in presenting calls to selected members first.
Pilot Distributed Hunt Group
Pilot Distributed Hunt Group directs calls to a pilot number. The System reviews who received the 
last call and begins hunting with the next member. If the last member in the group is reached and no 
member is available, the hunt continues with the first member and proceeds forward. After a complete 
search and no available member is found (extension is busy or there is no answer for a specified 
amount of time), the call is queued for the first member to become available. You can also set the 
Queuing Timer and specify how the long the System will search the initial hunt group before 
beginning to search the next hunt group or extension.
The main advantage of this type of hunting is that calls are evenly distributed throughout the group.
Switch Back Hunt Group
Switch Back Hunt Group initiates hunting in a specified group for calls made to a member extension 
in the group. If the called member of the hunt group is busy, the System begins hunting forward to the 
end of the group. If no member is available, the system hunts backward
 from the called member. If no 
member is available (extension is busy or there is no answer for a specified amount of time), the call 
is queued for the first member to become available. You can also set the Queuing Timer and specify 
how the long the System will search the initial hunt group before beginning to search the next hunt 
group or extension. 
The main advantage of this type of hunting is that calls can be directed to start with a selected portion 
of the hunting group based on the directed number. However, all members are eventually searched.

576-50-700 DBS 576 (USA) issued September 2001 3-35
Circular Hunt Group
Circular Hunt Group initiates hunting in a specified group for calls made to a member extension in the 
group. If the called member of the hunt group is busy, the System begins hunting forward to the end 
of the group and then moves forward
 from the first member of the group. If no member is available 
(extension is busy or there is no answer for a specified amount of time), the call is queued for the first 
member to become available. You can also set the Queuing Timer and specify how the long the 
System will search the initial hunt group before beginning to search the next hunt group or extension. 
The main advantage of this type of hunting is that calls can be directed to start with a selected portion 
of the hunting group based on the directed number. However, all members are eventually searched.
Next Extension/Hunt Group
Next Extension/Hunt Group lets you specify which extension or hunt group to search after the 
Queuing Timer expires. This hunt group can be set as any type of hunt group, an attendant group, or 
an extension (including virtual extensions).

Considerations
• If a member of the hunt group has Do-Not-Disturb (DND) or Call Forwarding - All set, that 
phone is temporarily removed from the hunt group.
• If a member of the hunt group has Call Forwarding - Busy set and the extension is busy, the call 
goes to the next phone in the hunt 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.
• A hunt group can contain both real extensions and virtual extensions. If virtual, several phones 
can be made to ring at the same time.
• The pilot number for a hunt group is flexible (i.e., any extension number can be designated as the 
pilot [not a real extension]).
• Hunt groups support the following call types:
•   Direct Inward Dialing (DID) / Dialed Number Identification Service (DNIS) / Direct 
Dial Inward (DDI)
•   Direct Inward System Access (DISA)
•   Extension calls
•   Private network attendant calls
•   Call forward incoming
•   Call forwarded to Attendant Hunt Group
• For Version 3.0 and higher, a queuing wait timer allows you to queue calls in a Hunt Group for a 
fixed period of time. When the call has passed through the Hunt Group once, the timer is

activated and the call is re-routed to the top of the group. The system continues to hunt for an 
available agent until the timer limit expires, and the call is diverted to another location.
Internal Hold Tone
Description
If a Music-on-Hold (MOH) sound source is unavailable, a periodic hold tone generated internally in 
the System can be provided to a caller. For more information, see “Music-on-Hold” on page 3-39.

LAN TAPI
Description
LAN TAPI opens a line of communications between the DBS 576’s switching 
systems and a PC. This is accomplished through the use of a Telephony Server 
connected to a LAN. Users on PCs can use specific applications to send and receive 
information to and from the DBS 576 via the LAN. Using a software program called 
the Telephony Service Provider (TSP), call control information (TAPI commands) is 
translated into commands that can be interpreted by the DBS 576. This “open” 
communication between the PC and the telephone system allows the user to initiate 
and handle calls via the application running on the PC.
Figure 3-1 on page 37 illustrates the major LAN TAPI components and system 
connections. 
						

							Section 700 - Operation Chapter 3. System Features
576-50-700 DBS 576 (USA) issued September 2001 3-37
Figure 3-1. LAN TAPI system
For example, a user at PC (1) selects the “Dial” function from the TAPI-compliant 
Personal Information Manager (PIM). The operating system routes this request over 
the LAN (2) to the main Telephony Server (3), which translates and forwards the 
request using Panasonic’s CT-API  Protocal over a serial connection (4) to the DBS 
576 (5). The DBS 576  then places the call from the users telephone (6).  The entire 
process is completed quickly and automatically once invoked by the user.
Hardware Requirements
• Windows NT network
• Telephony Server connected to the network
• Panasonic TSP software installed on the Telephony Server
• PC (Windows 95/98 or NT operating system)
• Supported TAPI application

MCO Tenant Group
Description
When the System is configured for tenant operation, MCO Tenant Group determines which trunks 
groups are used for incoming and outgoing calls. 
Each MCO trunk group is assigned to an MCO tenant group for incoming calls and for outgoing calls. 
By default, Trunk Group 1 is assigned to MCO Tenant Group 1, Trunk Group 2 is assigned to MCO 
Tenant Group 2, etc. for both incoming and outgoing calls. 
For outgoing calls, each tenant group has 5 auto-trunk selections available. By default the first auto-
trunk selection is seized by entering 9, the second by entering 81, etc.
The number of MCO tenant groups available depends on the number of ports in the system as follows:
•   96-port system: 1 to 12 MCO tenant groups
•   192-port system: 1to 24 MCO tenant groups
•   288-port system: 1 to 36 MCO tenant groups
•   384-port system: 1 to 48 MCO tenant groups
•   480-port system: 1 to 60 MCO tenant groups
•   576-port system: 1 To 72 MCO tenant groups

Related Programming
• FF1-3: MCO Incoming/Outgoing
• FF5-2: MCO Outgoing Trunk Assignments
• FF5-3: MCO Incoming Trunk Assignments
• FF2: Trunk Tenant Group Assignments
• FF3: Extension Tenant Group Assignments
Considerations
• When you first assign a trunk to a Trunk Tenant Group from the initial setting of (0), the system 
automatically assigns the trunks as a member of the same number MCO Trunk Group (FF5-2 and 
FF5-3). For instance, if Trunk 10 is assigned as a member of Trunk Tenant Group 1, then Trunk 
10 is automatically assigned as a member of MCO Outbound Trunk Group 1 and MCO Inbound 
Trunk Group 1. These assignments can be manually changed if desired.
Memory Backup
Description
Data stored in the CPC card can be copied to another CPC card in the OP2 card slot for the first 
cabinet. This is particularly useful when performed after completion of initial system setup (as a 
recovery measure) or before major changes are made to system configuration. This backup CPC can 
then be used to immediately restore system operation.
This feature is a maintenance feature to be performed by the System certified dealer only.
