Connecting the Cables
The ports on the rear panel are described below in order from top to
bottom of the rear card.
If you are using the PRI Bridge/Router Module, you do not connect to ISDN
using the ISDN ports on the rear card. The ISDN calls are routed along the
chassis’ backplane to the PRI Interface Module. See the AccessBuilder 7000
PRI Interface Module User Guide for more information.
ISDN Ports
(1&2)
There are two ISDN ports supporting two ISDN Basic Rate
lines on the BRI Bridge/Router Module. Connect these
ports to your ISDN wall box.
LAN Ports
There are three LAN connectors. Only one LAN port can
be used at any one time.
BNC
(3) – For connection to Thin Ethernet (10Base2).
RJ45
(4) – For connection to 10BaseT networks.
AUI
(5) – For connection to any cabling media using an
AUI cable and transceiver.
The two LEDs (6) show LAN activity. Yellow shows Tx
traffic and green shows Rx traffic. The rate at which the
LEDs flash indicate the volume of LAN traffic.
Manager
(7)
The Manager port enables a management PC or terminal
to be connected to the module using the 9-pin D-type to
RJ11 Serial Manager cable supplied with the unit. The port
provides VT100 terminal emulation, running at 9600 bps.
See
Appendix A
for more information about cables.
