Day/Night System Mode
Description
Day/Night System Mode enables you to switch the System between two Day modes and a Night 
mode. These modes determine incoming call handling, Toll Restriction Service (TRS) call handling, 
and attendant group support.
While in a Night mode (generally used at night or any time when your office is closed), incoming 
calls can ring at selected extensions (e.g., a night watchman’s extension or an extension connected to 
an answering machine). Outbound calls can be restricted to certain phones. Calls can be directed to a 
nighttime attendant group instead of the normal daytime attendant group.
The System provides one Night mode for night call handling. However, there are three night feature 
access codes (Night, Night 1, and Night 2). These three codes may be used to provide different two-
way Voice Processing Unit messages (i.e., Night may select one message, Night 1 may select a 
different message, and Night 2 may select a third message.)
Typically, the Day mode is used for normal call processing of outside calls, TRS calls, and attendant 
calls. The second day mode (Day 2) may be used for alternative call handling such as during a lunch 
break, etc. 
There are two ways to change day/night service modes:
•Manually
• Automatically
The following table lists the impact on TRS, Ringing, Attendant, and Built-in Voice Processing Unit 
in the various system modes:

• Day and Night modes can be assigned to FF keys on a phone. You can switch between Day 1, 
Day 2, Night, Night 1, and Night 2 modes simply by pressing the appropriate key. The FF key 
lights red when the System is in the assigned mode. 
• With CPC version 2.0 and later - Day 1/Day 2/Night toggle mode key can be assigned. Pressing 
the key toggles between modes. When in Day 1 mode, the FF key LED is not lit. When in Day 2 
mode, the LED lights green. When in Night mode, the LED lights red. 
• Prior to CPC version 2.0 - Day 1/Night toggle mode key can be assigned. Pressing the key 
toggles between modes. When in Day mode, the FF key LED is not lit. When in Night mode, the 
LED lights red.
Automatic Day/Night Mode
You can set the System to automatically enter a particular Day/Night mode determined by the time of 
day. Each day of the month can be assigned 1 of 3 automatic system mode patterns. Each of the 
patterns can be set to change modes up to 5 times per day. 
Up to 20 special days can be programmed with up to 5 automatic mode changes for the day. 
An Exception Day period is available for overriding the automatic mode for extended periods of time. 
For instance, if an office is shut down for the week of July 4th, the System can be programmed to not

The mode may be manually changed at any time.
For instance, the System can be set to automatically enter Day 1 mode at 8:00 a.m. on weekdays and 
enter Night mode at 5:00 p.m. on weekdays. All incoming calls, TRS and attendant group handling 
would change accordingly. On Saturday and Sunday, the System would stay in Night mode. 
The Automatic Day/Night modes may be set in User Maintenance. See “Set Mode Schedule” on 
page 4-15, “Set Special Day Mode” on page 4-24, “Set Exception Day Mode” on page 4-11, and “Set

• You can only set Automatic Day/Night modes on a system-wide basis. If tenant groups require 
separate Day/Night modes, you must set these modes manually.
• You can manually override Automatic Day/Night modes. (See “Manual Day/Night Mode” on 
page 3-24.)
Digital Pad
Description
Digital pad settings allow adjustment of call levels for different call types. There are 29 pad classes in 
the System. For pad class, a volume adjustment is assigned for a connection to any pad class 
assignment. The volume adjustment is between -30dB and +30 dB.
There are 8 extension pad classes and 16 trunk pad classes. In addition, there are pad classes for 
conference calls, page port, MFR, RAI Modem, and Conference Call Unit. One pad class is currently 
not used.
For instance, a call from an extension assigned to extension pad class 1 to a trunk assigned to trunk 
pad class 3 would received the volume adjustment assigned to this connection combination.

Direct Inward System Access 
Description
Direct Inward System Access (DISA) gives off-site users dial-in access to the System. You access 
DISA from an outside location by entering a digit number assigned to a DISA trunk.
For security reasons, 16 incoming DISA ID codes/TRS class can be assigned. If a code is assigned, it 
must be entered as soon as the DISA trunk answers.

Distinctive Ringing
Description
Distinctive Ringing sets CO calls to ring with a distinctive ring based on the trunk. This “ring” also 
identifies the call as an outside call instead of an inside call.
Beginning with CPC version 2.0, calls to a key telephone or DSLT can also be set to distinctive 
ringing on an extension basis.

Door Box
Description
The door box (also called door phone) allows visitors to announce their presence from the office door, 
etc. When the button on the door box is pressed, one or more phones ring in the System. When 
answered, a two way conversation is made between the door box and the answering phone. 
The answering party can operate a connected door opener (if equipped).
Operation
To answer a door box:
Hardware Requirements
• The door box requires a Door Box Adaptor (VB-43701), Door Box (VA-43705), and Door 
Opener. Door openers are not sold by Panasonic; however, they can be purchased from an 
electronics dealer.
• Up to 2 Door Boxes can be connected to a Door Box Adaptor and utilize the same trunk.
• The Door Opener can be set to open for 15 seconds, 30 seconds, or one minute.Action Result
1.   Answer the door box. (Door box calls ring in on a dedicated 
FF key.)Two way conversation possible
2.   Enter 3 while connected to the door box extension.  Door unlocks

Considerations
• The trunk connected to the Door Box Adaptor must be set to dial pulse (DP).
Door Box Sensor
The sensor is a device that detects when a circuit is opened or closed. Sensors can be used to detect 
events such as the opening of windows or doors. When the sensor is tripped, a tone sounds at a 
designated extension. Sensors are not sold by Panasonic; however, they can be purchased separately 
from an electronics dealer.
Hardware Requirements
• The sensor is attached to the Door Box Adaptor (VB-43701).
• Trunk lines connected to the Door Box Adaptor signal the designated extension when the sensor 
is tripped.

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 576HD 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).
