Sbc Board Cabling - Multitech CommPlete 4000 Quick Start Manual

If the ISI4608PCI or ISI4608UPCI is used, connections between it and external modems are made
via the supplied octopus cable going between the DB-78 connector on the ISI4608PCI board and the
DB-25 connectors on the individual modems. (RJ-11 connectors connect the modems to the phone
jacks.)
If the ISIHP-4S or -4U are used, note that each ISIHP card accepts as many as four RJ-45
connectors to accommodate ISDN BRI lines. (The modem connections that accommodate analog
calls are internal to the ISIHP board. That is, when the V.90 modem module is installed, each ISDN
B-channel connects to a V.90 modem via a digital connection. These digital connections allow analog
callers using 56K modems to receive 56k downloads from the ISIHP's modems.)
The SBC board has cable connectors for adding a monitor, a keyboard, a mouse or other serial
device (on COM1), and network connection. Cable connectors and boards are shown in Figure 3.

SBC Board Cabling

The SBC board is located in the CommPlete 4000 as shown in Figure 3. The SBC board cabling may
involve connection to four back panel connectors (see Figure 4). The back panel connectors are:
• Video connector
• COM 1 connector
• Keyboard connector
• Network connector
The right connector (COM 1) on the SBC's backplane typically accommodates a mouse or other
pointing device. The RJ45 connector to the left is the network connection. The next receptacle to the
left connects the video cable to a monitor. The left round connector is for the keyboard.
Note: Any cables connected to the CommPlete 4000 should be shielded to reduce
interference.
