To install a Quad BRI network interface module:
1. Make sure your system is powered off.
2. Connect the system side of the Quad BRI network interface module to the
system using the network interface cable that is color-coded light blue on one
end, green on the other.
3. Connect the network side of the Quad BRI network interface module to the
NT-1 device or to the ISDN network, as appropriate. If you do not connect BRI
lines to all four ports, connect the ports in ascending order.
4. If you are using an NT-1 device, connect it to the ISDN network.
