Vertical Communications GCA70-313 - Manual (Page 79)

DSS/BLF Console Operation
The IB64X, IB48X, and IB24X
DSS/BLF consoles have additional buttons and
status lights that extend the memory button capability of an adjacent companion
telephone. The buttons can be programmed for automatic dialing (speed dial) or
direct station selection (DSS) with busy lamp field (BLF) using the instructions
provided previously in this guide.
When the installer assigns a
DSS/BLF console to a station port, the system recognizes
it as such and automatically clears (blanks) the console buttons so that you can store
numbers at the buttons as you need them.
