Hardware overview/installation
IVX 20 hardware components consist of a system cabinet configuration of 4 × 8 that can be ex-
panded to a maximum configuration of 6 × 12 × 2.
System cabinet
The wall-mounted
cabinet
, measuring 8 ½

″
D, is designed for easy installation and
easy component access. It houses the Memory Module and main board, as well as the optional
14.4 Kbps modem. It is capable of supporting one expansion card.
Main board
The main board combines leading-edge hardware components, including a Motorola

processor and DSP structure, along with proprietary operating system software. The board pro-
vides:
•
System control of the Memory Module
•
Four CO line interfaces
•
Eight digital station interfaces
•
A standard RS-232 DB9 serial port
•
An external paging-device interface and MOH interface.
Modem option
The base unit can be ordered with or without the optional on-board modem; it provides for remote
system programming and software updating. An IVX 20 without the modem cannot be field-
upgraded to include it; it must be ordered at purchase time.
Memory Module
The
Memory Module
is a hard disk drive with proprietary formatting; it contains all system program
and configuration data, as well as pre-loaded voice prompts. The drive holds 30 hours of voice
storage at the industry's highest quality sampling rate — 64 Kbits/second.
Expansion card
The expansion card connects directly to the main board and adds an additional two CO lines, four
digital station ports and two analog ports. The external connections are accomplished through the
Amphenol connector on the main board.
Digital Feature Phone
Each IVX Digital Feature Phone is equipped with a speakerphone, 32-character display, and both
fixed and programmable feature keys. Phones connect to the cabinet via a standard two-wire
twisted pair.
