Features
Automatic Slot Con figuration
Description
Automatic Slot Con figuration automatically sets up station and line PCBs when you initially \
power up the 
system. This simpli fies installation because you don’t have to use system programming to activate station 
and line PCBs after you plug them in.
Here’s how Automatic Slot Con figuration works:
1.With power off, install your station and line PCBs.
2.With the system powered down, install the station and line PCBs from left to right in the order yo\
u want 
your extension and line numbers set up.
• Be sure to install a 16ESIU PCB in the  first slot (CN1).
• You don’t have to group your station and line PCBs together, although it may be more convenient to  do so.
3.Power up the system.
4.On power up, the system scans the PCBs from left to right and sets up the extension and line numbering 
as follows.
• Extension numbers will begin with 300 in the  first slot and increment from left to right.
• Line numbers will begin with 101 (starting from the  first installed line PCB) and will also increment 
from left to right.
System reset does not cause recon figuration. Automatic Slot Con figuration is temporarily disabled during a 
system reset.
Programming
1.Use  120x-Stations  (page 611) to recon figure your station PCBs.
1.Use  121x-Lines  (page 614) to recon figure your line PCBs.

Background Music
34◆Features DSX Software Manual
Background Music
Description
Background Music (BGM) sends music from a customer-provided music source to speakers in keysets. If an 
extension user activates it, BGM plays whenever the extension is idle. Incoming calls and Paging announce-
ments temporarily override (turn off) Background Music. Background Music requires a customer-provided 
external music source connected to one of two audio input minijacks.
❥In DSX-40, the audio input minijacks are located on the equipment cabine\
t.
❥In DSX-80/160, the audio input minijacks are located on the CPU PCB.
The external music source you connect to the audio input minijacks is typical\
ly a CD player or FM receiver. 
The source, which you can also use for Music on Hold, must be compatible\
 with the following speci fications:
For more on connecting a customer-provided music source, refer to the system’s Hardware Manual.

Battery Backup
38◆Features DSX Software Manual
Battery Backup
Description
In the event of commercial AC power failure, the NAND Flash memory on the CPU PCB permanently main-
tains the site database. Additionally, an internal battery on the CPU provides short-term backup of the sys-
tem date and time (Real Time Clock) and certain station parameters (such as the Caller ID log)\
. The battery 
will hold the Real Time Clock and station parameters for up to 10-14 days. When commercial AC power is 
restored, the system restarts with all programming and the time and date\
 intact.
Additional Battery Backup capability can be provided by a customer-supplied Uninterruptable Power Sup-
ply (UPS). The length of time the UPS will power the system when power fails depends on the capacity of 
the UPS unit. Consult with the UPS manufacturer for the specifics. Refer to the  Hardware Manual  for addi-
tional details.

The system’s internal battery backs up the CPU Real Time Clock for 10-14 days.

Call Coverage Keys
40◆Features DSX Software Manual
Call Coverage Keys
Description
A keyset can have Call Coverage Keys for a co-worker’s extensions, Ring Group master numbers and UCD 
Group master numbers. The Call Coverage Key lights when the co-worker’s extension is busy,  flashes slowly 
when the co-worker has an incoming call, and  flashes fast when the co-worker is in Do Not Disturb. The Call 
Coverage Key can ring immediately when a call comes into the covered extension, ring after a delay or not 
ring at all. In addition, the keyset user can press the Call Coverage Key to intercept their co-worker’s incom-
ing call. They can also go off hook and press the Call Coverage key to call the covered extension. An exten-
sion can have as many Call Coverage Keys as they have available Feature Keys on their telephone.
Call Coverage Keys  will intercept the following types of calls:
❥Key Ring Calls
❥Ringing Intercom calls
❥Calls to a UCD Group master number
❥Calls ringing a Group Ring master number
❥Transferred calls
Call Coverage Keys  will not intercept a call ringing the attendant’s Operator Call Key.
Call Coverage Guard Timer
The 4 second Call Coverage Guard Timer helps extensions that have the same Call Coverage key assign-
ments. As soon as an extension user presses their Call Coverage key to answer a call, the key becomes 
unavailable for 4 seconds to all other extensions with that same key. (Users will hear reorder tone if they 
press their key before the 4 seconds expire.) This helps prevent users from inadvertently placing a call to the 
covered destination.
Conditions
• None
Default Setting
• No Call Coverage Keys assigned.
• The Call Coverage Delay Ring timer is 10 seconds.
Call Coverage keys allow an extension user to cover a co-worker’s calls from their own telephone.
