Expansion Cabinets

Each ESI Communications Server can be expanded to increase the number of port cards. The ESI-1000 and
ESI-600 each accept the same Expansion Cabinet, while the ESI-200, ESI-100, and ESI-50 have their own
unique Expansion Cabinets.

Main board

The main board combines leading-edge hardware components — including a Motorola
and 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; MOH interface; an NSP, which provides remote access via TCP/IP and
supports certain optional ESI PC software applications; and (except on the ESI-100 and ESI-50) a mount for the
Mirrored Memory Module.

Backplane

On the ESI-1000, ESI-600, and ESI-200, each cabinet (Base or Expansion) is equipped with a backplane that
supports up to seven port cards.

The M3 interface is standard on the ESI-1000, optional on the ESI-600 and hard drive-equipped ESI-200. Each requires an optional second
Memory Module.
