The Base
Cabinet can support one Expansion Cabinet for a potential total of three 482 port cards (see next item), and one
4 8 2 main board.
Expansion Cabinet
You can “piggy-back” an Expansion Cabinet to the front of the IVX S-Class Base Cabinet. The Expansion Cabinet
adds two expansion slots, enabling the system to grow to its maximum configuration: main board plus three port cards.
Main board
The main board combines leading-edge hardware components — including a Motorola
®
ColdFire
®
processor and Texas
Instruments
®
DSP structure — along with proprietary operating system software. The board provides: system control of
the Memory Module and port cards; a standard RS-232C DB9 serial port; a built-in modem for remote access; an
external paging-device interface; and MOH interface. The IVX S-Class main board has a four-line, eight-digital station,
two-analog port configuration. On IVX S-Class Base Cabinets that include the Network Services Processor (NSP), the
NSP is pre-installed on the main board.

The Memory Module and port cards are packaged separately and are mounted in the cabinet during installation.

IVX S-Class Base Cabinets are available either with built-in NSP or a non-NSP configuration. The non-NSP Base Cabinet cannot be
field-upgraded to include an NSP.
