The Conference
Board
The DXP services board provides for a limited amount of
conferencing. If additional conferencing is required, you may need to
install a conference board (DXCNF). Each conference board provides
five additional three-way conferencing circuits. You can install a
conference board in any universal or universal / auxiliary slot, and you
can install multiple conference boards. For more information on the
Conference board, see lMI66-085.

cabinet holds up to eight additional boards. As its name indicates, the
expansion cabinet simply increases the number of stations and lines

that you can have on the DXP system.
The far left of the cabinet houses the expansion-cabinet power supply;
this power supply is designed specifically for the expansion cabinet.
Chapter three discusses the power supply in more detail. The
backplane and card cage are very similar to those in the main cabinet.
This first slot holds the interface 2 board. The interface 2 board
connects to the interface 1 board to secure the integrity of the digital
signals between the two cabinets. You must have an interface 2 board
if you are going to use an expansion cabinet. The remaining slots in
the expansion cabinet, universal slots 6 - 12, each can hold either a
line, conference, or station board. You cannot use an auxiliary board
in the expansion cabinet. For more information on the expansion
cabinet, see IMI66-086.
