Wiring the 800 CO-BRI Module
The wiring running from the network interface to the 800 CO-BRI module is the
same as that for other line modules, which is usually a D8W cord. However, this
depends upon the network interface used. See the MERLIN LEGEND
Communications System Installation manual (555-620-1 41) for complete
information.
As mentioned, the 800 CO-BRI module is a two-wire interface. This means that
the interface operates on two-wire, twisted-pair cables of mixed gauges. The two
wires are reversible—they are not polarity sensitive. Table 2-3 shows the pin
assignments for an 8-position jack connected to the 800 CO-BRI module.
