Console DSS/BLF Interface Unit
The Console Direct Station Select/Busy Lamp Field (DSS/BLF) Interface Unit allows the
association of one PKM48 with an attendant console. The PKM48 provides the attendant
console user with the ability to determine which extensions are busy by glancing at the LED
indicators. The unit provides additional line monitoring of directory numbers for speedy call flow
and functions as a stand-alone BLF interface unit (DSS functionality is not provided).
Note: Headsets and handsets cannot be attached to this unit.
The Console DSS/BLF Interface Unit uses a separate line connection to a DNIC port. The
PKM48 attaches to the Console DSS/BLF Interface Unit and is associated with the attendant
console through Customer Data Entry (CDE). The maximum cable length between the unit and
the PKM48 is 5m (16.4 ft).
For installation instructions, see the SX-2000 Install Peripherals section of the Technical
Documentation CD-ROM.
