System Overview
The CommPlete™ 4000 Communications Server is a single-segment, rack mountable
communications server. It is customized for dedicated turnkey operation of LAN-based
communications and remote access server functions. The CommPlete 4000 is a general purpose,
turnkey communications server that easily interfaces to any existing Novell, Windows NT, or IP
network.

Product Overview
The CommPlete 4000 is a ruggedized, highly expandable 19" rack mount device that includes a built-
in hard drive, 3.5" floppy drive, and a slot for a CD-ROM drive. It has five circuit-board slots: four are
PCI compatible, and one accommodates either a PCI or ISA card. (Each CommPlete 4000 model is
shipped with a Network Interface Card and a MultiModem ISI card. These occupy two slots, leaving
three slots for expansion cards.) A separate slot supports the single board computer (SBC) that is
the heart of the system. A user configurable card cage allows for up to 32 V.90 (56kbps, KFlex)
internal modems or up to 32 high speed serial ports. The CommPlete 4000 is shipped with factory-
installed RAS
Express server software for remote-access functionality. Each CommPlete 4000 has a
default configuration that allows it to boot as a RAS unit.
The four CommPlete 4000 models differ according to the serial interface card used. The different
serial interface cards offer, variously, serial ports for external modems, built-in modems, or built-in
modems and terminal adapters:
Model CC4S-8 with the ISI4608PCI or ISI4608UPCI serial card -- has serial port connections for
eight external modems.
Model CC4M-8 with the ISI5634PCI/8 or ISI5634UPCI serial card -- has eight built-in modems
Model CC4H-4S with the ISIHP-4S serial card -- provides four ISDN terminal adapters using the S
interface as well as eight analog modems (allowing eight concurrent sessions)
Model CC4H-4U with the ISIHP-4U serial card -- provides four ISDN terminal adapters using the
U interface as well as eight analog modems (allowing eight concurrent sessions)
The CommPlete 4000 has expansion capability for up to three additional MultiModem ISI circuit cards
(for additional modems/TAs). When multiple serial-interface cards are used, the CommPlete
accommodates or includes as many as 32 communications devices. While it is most common to use
multiple ISI cards all of the same type, you can equip a single CommPlete 4000 unit with more than
one type of ISI card.
