/

″ W × 11″ H × 3″ D, and is designed for easy instal-
lation and easy component access. It houses the Memory Module and Main Board, a 612, 684,
A12, D12 or DLC12 port card (see page B.2), two serial ports and a MOH connector. It can support
one
Expansion Cabinet
, for a total of three port cards.
Base Cabinet II

net II
via ribbon cable to the Base Cabinet I. The Base Cabinet II houses up to two port cards; it can
also support one Expansion Cabinet.
Expansion Cabinets
You can “piggy-back” an
Expansion Cabinet
to the front of each Base Cabinet. Each Expansion
Cabinet houses up to two additional port cards each, enabling the system to grow to its maximum
128-port configuration (seven port cards).
Main board
The main board combines leading-edge hardware components — including a Motorola

ColdFire
®
processor and DSP structure — along with proprietary operating system software. The
board provides:
• System control of the Memory Module and port cards
• Two standard RS-232C DB9 serial ports
• A built-in 33.6 Kbs modem for remote access
• An external paging-device interface
• MOH interface
