Busy Lamp Field BLF

The BLF is a key module for optiPoint 500 and 600 that can be connected to the telephone over
an 8-pin RJ45 communications port.
It can be used in the HiPath 3000/Hicom 150E/H and HiPath AllServe 150 systems and has
the same functions as the existing BLF on optiset E telephones.
The BLF on the basic, standard and advance
models allows phone numbers and functions
to be saved (e.g. callback, conference, last
number redial, etc.)
It has
90 function keys,
●
90 LEDs for visual signaling of the activat-
●
ed functions and keys.

Power Supply

The BLF has its own local power supply. If you want to connect two BLFs, you need only one
local power supply for them both (i.e. the power supply of the first BLF can be used for the sec-
ond BLF as well).
The BLF uses the same power supply (power supply unit 2x35V) and connector as the optiPoint
500 a/b adapter (also see chapter "Accessories" --> "Mains adapter").
The output of power supply must be connected directly with the optiPoint BLF.
