Installing the Quad BRI network interface outside the
conference room
You can locate the system up to 250 feet away from the Quad BRI network interface
module, with the following provisions:
❑ If the distance from the system to the Quad BRI network interface module is
less than 50 feet, no additional power is required.
❑ If the distance is between 50 and 250 feet, you must use a 9-volt AC/DC
transformer to boost power (such as the Digi-Key #T405-ND). Connect the
transformer to the Quad BRI network interface module.
❑ RJ-45 jacks, connected to 110 blocks or 66 blocks, should be installed in the
wiring closet. You can then connect these jacks to the Quad BRI network
interface module with the supplied RJ-45 cables.
