4 MultiModem ISI Server Cards User Guide
Chapter 1 – Introduction and
Description
This manual describes the Multi-Tech Intelligent Serial Interface, Server Cards Models ISI5634UPCI-4/8 and
ISI9234PCIE-4/8. The UPCI Cards install on Universal PCI-bus architecture and the PCI Express cards install on PCI
Express-bus architecture.
We assume that you have basic PC skills. Therefore, we have not included step-by-step instructions for basic
computer operations.
ISI Server Cards
The ISI Server Card model ISI5634UPCI uses Universal PCI-bus architecture. The ISI9234PCIe uses PCI Express-bus
architecture. The -4 ISI Server card is a server modem expansion card with four V.92 data/Super G3 fax modems.
The -8 ISI Server card is an expansion card with eight such modems. These products add modems to
communication servers and async hosts that have 32-bit PCI bus architecture.
The Multi-Tech Systems Installation Resources
website has drivers for the ISI Server Cards for the following
operating systems: Windows
®
2000 Server and Advanced Server, Windows 2000 Professional, Windows 2003,
Windows XP, Windows Vista, Windows 7, Windows Server
®
2008, and Linux kernel 2.4.x. It also has instructions
for using Linux kernel 2.6.x built-in drivers.
Combine ISI Server Cards to support asynchronous serial devices (local or dial-up). The ports can be used to
connect basic terminals (with or without multiple pages of memory) to multiplexer channels and asynchronous
modems. Each port can support as many screens as there are physical pages of memory on the terminal.
Windows 2000/2003/XP/Vista/2008/7 includes a built-in autodetect utility that detects Multi-Tech modems and
sets the proper initialization strings.

ISI5634UPCI Card
The -4 server card has one RJ-45 connector that fans out into four RJ-11 connectors, one for each of its modems.
Similarly, the -8 server card has two RJ-45 connectors that fan out into eight RJ-11 connectors, one for each of its
modems. Both server cards are full size add-on cards that support a high-speed interface up to 230 Kbps.
ISI Modems
The ISI modems are compatible with the ITU-T V.92 protocol. They make quick connections and operate at
downstream transmission speeds of up to 56K bps and upstream transmission speeds of up to 48K bps when
connected to V.92-compatible Internet Service Providers. The V.92 protocol can send data downstream from the
Internet to your computer at these speeds because data on the telephone network typically is converted from
