charge to the backup batteries, which have a 3-year life and can support the phone system for up to
30 minutes at a time.
Diagnostic Maintenance
The printed circuit board (PCB) cards are designed to slide easily into slots within the DBS 576
cabinet. By using diagnostic troubleshooting, small problems can be isolated to specific cards. Some
cards are designed to be installed and extracted from slots without turning off the power, allowing
system maintenance to be completed without interrupting the entire system.
For example, say you're having a problem with one of the trunks on a Loop Start/Ground Start Trunk
Card. Instead of having to turn off the power, or reprogram anything, or alert anyone to get off the
phone, all you have to do is throw a Maintenance switch on the Card. This will busy-out the trunks on
that Card that aren't being used at the moment, but will leave the trunks in use alone, allowing people
to finish their phone calls without any disruption. The LEDs on the Card will tell you when the trunks
become vacant. When all LEDs are extinguished, the Card can be replaced.
Programming the Phone System
Programming can be accomplished in several ways without disrupting normal phone system
operation. Most programming changes take place as you are programming, what we refer to as "live"
programming.
Programming from a display telephone.
Programming can be performed on any small-display or large-display extension phone. A large-
display phone is recommended because its LCD buttons can perform special one-touch functions in
programming (such as "stepping" through addresses, entering a pause in a speed-dial number, etc.).
Only authorized access is allowed; you must enter a valid password to get into Programming mode.
Programming from the RS232 port.
A PC computer or laptop can be connected to the DBS 576 phone system, via a DB9-pin RS232 port
on the SCC card inside the cabinet. Then, from the computer, you can program the phone system
with our proprietary PC-based software, DBS 576 Manager.
This popular software package runs in a Windows 95 or Window 98 environment and makes
programming and maintaining phone systems easy. With DBS 576 Manager, multiple phone systems
can be maintained in separate databases on the computer. The phone system parameters are
grouped together in windows so you can see the current settings all on the same page. To set a
parameter, simply click a button, or select from a multiple-choice field, or type in an entry. It even has
context-sensitive help if you get stuck (press F1 and a help screen will pop-up, explaining the field
you're in).
You can use DBS 576 Manager to "build" a phone system, then download it into the phone system's
memory all at once. Or you can perform individual, "live" changes to phone system memory from the
computer. It can also be used for backing up and restoring phone system databases.
Programming from a remote location.
Again using DBS 576 Manager, the DBS 576 can be programmed from a remote location, using an
offsite computer terminal to call into the phone system. You can perform "live" changes in this manner
as well as downloads/uploads (for backup/restoring).
