Installing Your CommPlete 4000

ISI Board Cabling

Each Intelligent Serial Interface card (ISI5634PCI/8, ISI5634UPCI/8, ISI4608PCI, ISI4608UPCI or

ISIHP-2S/2U) takes up one physical slot in the CommPlete 4000. Depending on your configuration,

you may have as many as four of these cards (see Figure 3). Attach the line cords (RJ-12 for analog

phone lines; RJ-45 for UPCI or ISDN phone lines) to the line connectors on the ISI card(s) at the

back of your CommPlete 4000 as shown in Figure 5.

Note: Any cables connected to the CommPlete 4000 should be shielded to reduce

interference.

Note that the two top expansion slots share a data interrupt signal on the PCI bus. Consequently, if

both slots are used, they must be occupied with identical devices (and the device drivers must be

identical). This is a constraint of PCI bus architecture. Also, the device drivers must support

"interrupt-sharing." The drivers for the MultiTech ISI card do support interrupt-sharing.

other MultiModem ISI cards differ)
