Direct Station Select/Busy Lamp Field Units

The Inter-Tel 5000 platform supports two 60-button DSS/BLF Units and one 50-button model.
Although you can use either type of DSS/BLF Unit on any of the endpoints, the type of endpoint
determines which is the more appropriate unit to use.

DSS/BLF Units always require dedicated AC transformers. For a diagram of AC transformer
requirements, see Figure 5-70 on
"Connecting DSS/BLF Units" on
Each DSS/BLF Unit provides one-button access to 50 or 60 extension numbers, trunks,
features, or other resources, and four units provide access to 200 or 240 extensions, features,
and resources. Numbers programmed for the buttons can be endpoint extension numbers, hunt
group numbers, trunk access codes, or feature codes.
The layout of the buttons and the numbers are assigned using one of 20 keymaps in DB
Programming. The intercom number/button assignments of each keymap are programmed in
four lists, pages 1–4. For example, single DSS/BLF Units are assigned page 1 of the desired
keymap, tandem units are assigned two pages of the desired keymap—page 1 for the first unit
and page 2 for the second unit, and so on. For programming instructions, refer to the Inter-Tel
5000 Features and Programming Guide (part no. 580.8006).
Together, the lamps in the buttons create a Busy Lamp Field that indicate the status of each
station, hunt group, or other feature/resource assigned to the buttons. If assigned to a station,
the LED indicator in the button is solidly lit when the associated station is busy or unplugged,
flashes slowly when the station is in Do-Not-Disturb (DND), flashes rapidly when the station has
a call ringing in, or flutters continuously if the station is causing a STATION OFF-HOOK system
alarm.
If assigned to a hunt group, the LED indicator is solidly lit when all stations in the hunt group are
unavailable, either busy, in DND, or removed from the hunt group. The LED indicator flashes
rapidly when a call is camped-on to a hunt group. If assigned to a feature or resource, the LED
indicator is lit to show busy status and unlit to show idle status.

DSS/BLF Units can be installed on a system, or node. Each unit is powered by a 450 mA
AC transformer and connected to the PCDPM installed in the endpoint. The 6-rows-by-10-
columns model, part no. 550.4200, is designed for Executive and Standard Display
endpoints. The 12-rows-by-5-columns model, part no. 560.4000, is designed for
Professional and Associate Display endpoints.
With Models 8520 and 8560 endpoints: PCDPM-equipped Models 8520 and 8560
endpoints support up to four Model 8450 with 50-button DSS/BLF Units, part no.
550.8450. Up to 20 of the 5-rows-by-10-columns DSS/BLF Units can be installed on a
system. Each unit is powered by a 450 mA AC transformer and is connected to a PCDPM
installed in the endpoint. For PCDPM installation instructions, see "Installing a PCDPM" on
page 5-183.
