installed in the phone. The 6-rows-by-10-columns model, part number 550.4200, is designed
for Executive and Standard Display phones. The 12-rows-by-5-columns model, part number
560.4000, is designed for Professional and Associate Display phones.
PKM 50 and 60-button DSS/BLF units always require dedicated AC transformers. For a diagram of
AC transformer requirements, see Figure 8 on page 348 . For installation instructions, see
“Connecting DSS/BLF Units” on page 1-357 . Unit dimensions appear in Table 24 .
Each 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 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
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 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.
8416 Mini-Direct Station Select (Mini-DSS) Unit
The MiVoice Office 250 supports a PKM 16 (previously known as the 8416 Mini-DSS Unit) that
provides one-button access to 16 extension numbers and/or feature buttons/resources. The optional
PKM 16 can be attached to 8520, 8560, and 8660 phones.
