MISCELLANEOUS WIRING INSTALLATION

Installing Attendant Console

Requirements
The attendant console is connected to an information outlet the same as any other voice
terminal. Figure 4-56 shows the connections required for the attendant console.
Power for two consoles only can be provided by the switch cabinet through an auxiliary
cable connected to the Trunk/Auxiliary Field. Whenever possible, power for the primary
attendant console should be provided by the switch cabinet. This makes the primary console
fully operational during short (less than 10 seconds) power outages.
Note: The attendant console cannot be powered from the switch cabinet on the System
75 XE.
Additional attendant consoles are remotely powered by the 346 bulk power supply or
individual power units. Refer to ADJUNCT POWERING for details on remote powering
from adjunct power units located at satellite locations, site locations, or information outlets.
Note: The 329A Power Unit should not be used to remotely power the attendant
console.
The maximum cabling distance for the attendant console powered from the switch cabinet is
350 feet (107 m). Maximum cabling distances for additional attendant consoles is 2400 feet
(732 m) for 24-gauge wire and 1500 feet (457 m) for 26-gauge wire.
