1-24 DBS 824-3.0/3.2-700 Revised April 2000
Music-on-Hold
(CPC-S and CPC-M)
Description
The DBS 824 can provide Music-on-Hold to parties on hold on a CO line. 
The Music-on-Hold feature can also be used to play announcements or 
advertisements if desired.
The system can provide Music-on-Hold with the internal MOH resource on 
systems using the MFR card option (CPC-M only). See “Background Music” 
on page 1-10 for more information.
Hardware Requirements
 The music source must be purchased separately. It is not provided with the 
DBS 824.
 If a single music source is used for both Music-on-Hold and background 
music, the music source connects to the CN6 on the CPC. If a separate 
music source is used for background music (CPC-M only), it connects to 
CN6 and music-on-hold connects to CN8. See Installation (Section 300) 
for instructions.
 The input impedance for the music source is 10k ohms. 
 The maximum input level is 10 dB.

Description
The Attendant can switch the system between Day and two Night Modes for 
answering outside calls. It is also possible to program the system to 
automatically switch between night and day modes. 
While in a Night Mode (generally used at night or any time when your office 
is closed), incoming calls can ring at selected extensions (a night watchman’s 
extension, for example), an extension connected to an answering machine, or 
to a Universal Night Answer point. Universal Night Answer (UNA) is used to 
allow calls to be picked up from any extension.

Hardware Requirements
 Calls during Night Mode are often indicated by external paging speakers or 
an external ringing device, such as a night bell. External paging and 
ringing devices are not provided with the DBS 824; they must be 
purchased separately.
Considerations
 Day, Night and Night 2 modes can be assigned to FF keys on an attendant 
phone. The attendant can switch between Day, Night and Night 2 modes 
simply by pressing the appropriate key. The FF key lights red when the 
system is in the assigned mode. Alternatively a DAY/NIGHT1/NIGHT2 
toggle mode kay can be assigned. Pressing thekey toggles the mode. When 
in Day mode, theFF key LED is not lit. When in NIGHT1 mode, the LED 
lights red. When in NIGHT2 mode, the LED lights green.
 If the same mode key is assigned on different attendant positions, each key 
indicates the current mode. For instance, if a NIGHT1
 key is assigned for 
two attendants, both light when in NIGHT1
 mode.
 If the system is programmed to switch between night and day modes 
automatically, you cannot switch between modes by using the “#520/#521/
#522/#523.” 
						

							System Features Off-Premises Extension
Revised April 2000 DBS 824-3.0/3.2-700   1-27
Off-Premises Extension
(CPC-S and CPC-M)
Description
SLTs that are located in remote locations can be connected to the DBS 824 
through the Off-Premises Extension (OPX) Adaptor. 
Off-premise phones can be connected through a direct line to the DBS 824 or 
through the central office, depending on how far they are from the main 
cabinet. For specifications, see Installation (Section 300). 
Operation
Feature operation for OPX extensions is the same as for local SLTs connected 
to the DBS 824.
Related Programming
 FF3 (Extension): Terminal Type
Hardware Requirements
 One OPX Adaptor (VB-43702) is required for each OPX extension.
 When OPX extensions are connected through the central office, an 
external ringer supply may be required. If required, the ringing supply is 
connected to the OPX Adaptor.
Considerations
 Up to 6 OPX extensions can be connected to a system.
 The DBS 824 side of the OPX Adaptor is connected to a digital extension 
port. 
						

							Paging System Features
1-28 DBS 824-3.0/3.2-700 Revised April 2000
Paging
(CPC-S and CPC-M)
Description
Internal paging is accomplished through the speakers of your system’s key 
phones. The Paging feature allows you to contact someone temporarily away 
from an extension, give instructions to an entire group, or communicate with 
several people at once. If an external paging system is connected to your 
system, pages can also be sent through its speakers.
The Paging feature can also be programmed to time out after sixty seconds. 
When a page call times out, a busy tone is sent to the extension that initiated 
the page.
Operation
To use the Paging feature:
1.  Pick up the handset.
2.  Press “#,” then enter the number of the desired Paging Group (00-07).
The EXT
 LED lights.
3.  Make your announcement.
4.  Replace the handset.

							System Features Power Failure Transfer
Revised April 2000 DBS 824-3.0/3.2-700   1-29
 If an external paging system has been connected to Paging Groups 00-07, 
pages can be made through the external speakers. Voice Paging can also be 
heard over the extensions in groups 00-07.
 An extension can belong to more than one paging group.
 A maximum of eight Paging Groups can be assigned to a system.
 Additional pages cannot be sent when someone is paging group 00. In fact, 
if you page group 00 while other extensions are paging groups 01-07, the 
latter operations will be terminated, and “Page Overridden” will appear on 
your display.
 Paging cannot be heard at busy extensions or at extensions for which the 
Do Not Disturb, Call Forwarding, or Absence Message feature is activated. 
 You can answer Paging from an idle extension by dialing the Meet-Me 
Answer code (“77”).
 The Meet-Me Answer feature cannot be used at an extension that is off-
hook at the time of the Paging Call, even if the extension later goes 
onhook.
 The Meet-Me Answer feature cannot be used with Paging Group 00.
Power Failure Transfer
(CPC-S and CPC-M)
Description
This feature provides telephone service to a limited number of SLTs during a 
power failure. The SLTs are connected to the CO via a Power Failure Unit 
(PFU). 
In the event of a power failure, the power failure extensions have dial tone 
directly from the CO; system features and restrictions do not apply.
Hardware Requirements
 Power Failure Unit (VA-43703)
 An SLT that will be connected to the PFU 
						

							Power Failure Transfer System Features
1-30 DBS 824-3.0/3.2-700 Revised April 2000
 A Single Line Telephone Adapter (VB-40709) is required to provide 
analog ports to the PFU.
Considerations
 Up to four SLTs can be connected to one Power Failure Unit.
 If a call is in progress through the PFU when the power is restored, the call 
will be disconnected.
 For added protection against power outages, backup batteries can be 
installed in the DBS 824. Backup batteries provide full telephone service 
and system features to all DBS 824 extensions for a limited amount of 
time. 
With maximum traffic, the backup batteries last up to 40 minutes.  
						

							System Features Remote Maintenance
Revised April 2000 DBS 824-3.0/3.2-700   1-31
Remote Maintenance
(CPC-S and CPC-M)
Description
The DBS 824 can be programmed from a remote terminal or from a remote 
PC by connecting via modems to the Maintenance port on the Serial Interface 
Unit (SIU). The Remote Programming Mode may also be used locally by 
directly connecting to the Maintenance Port.
Remote Programming Mode
(CPC-S and CPC-M)
Description
Remote Programming Mode uses a modem connected to a “dumb” terminal 
or a PC terminal program to access a modem connected to the DBS 824 
Maintenance serial port. Local programming bypasses the modems and 
connects directly from the PC or terminal to the Maintenance serial port.
When programming from a terminal connected to the RS-232C 
(Maintenance) port either directly or via a modem, perform the following 
steps:
1.  Make certain that any cables and modems are configured and connected 
as outlined in Section 300.
2.  Have someone at the site set the DBS 824 to the terminal 
communications mode by entering the following command at a digital 
extension: 
#99xxxx
 (where xxxx = the site’s password)
3.  Enter your terminal communications program and make sure your PC’s 
data communications settings match those of the DBS 824.
4.  If connecting remotely using modems, dial up the DBS 824 Maintenance 
port modem following the procedures for your terminal package. After 
the DBS 824 displays the DBS Remote Programming Banner Screen, 
type P 
and 
then press Enter
.
5.  Follow the directions on the screen to access the desired programs. (See 
“Terminal Programming Commands.”)
