Phone Physical Features
The following sections describe physical features of phones that operate on the MiVoice Office 250.
DSS/BLF Unit
The MiVoice Office 250 supports two 60-button Direct Station Select/Busy Lamp Field
(DSS/BLF) Units and one 50-button model. Although you can use either type of DSS/BLF Unit on
any of the phones, the type of phone determines which is the more appropriate unit to use.
• PC Data Port Module (PCDPM)-equipped Executive, Professional, Standard, and Associate
Display phones can support up to four 60-button DSS/BLF units. Up to twenty 60-key DSS/BLF
Units can be installed on a system. The 6-rows-by-10-columns model, is designed for Executive
and Standard Display phones, and the 12-rows-by-5-columns model is designed for Professional
and Associate Display phones. For more information, refer to the “Specifications” chapter in the
MiVoice Office 250 Installation Manual
.
• PCDPM-equipped 8520 and 8560 phones support up to four 8450 50-button DSS/BLF units.
Up to 20 of the 5-rows-by-10-columns DSS/BLF units can be installed on a system. For speci -
fications and installation instructions, refer to the “Specifications” and “Installation” chapters in
the
MiVoice Office 250 Installation Manual
.
DSS/BLF Units always require dedicated AC transformers. For a diagram of AC transformer
requirements or unit installation instructions, refer to the “Specifications” and “Installation” chapters
in the
MiVoice Office 250 Installation Manual
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 phone 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 more information about keymaps, refer to the “Phones and Devices” chapter in the
MiVoice
Office 250 Features and Programming Guide
.
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—
whether 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.
NOTE
Group Call Pick-Up does not affect DSS lamp status any differently than standard hunt group
calls or individual calls.
