!
CAUTION:
Do not use the 329A power unit for the attendant console.
The nonessential functions of an attendant console and its optional 26A1 or 24A1 selector
console derive their power from an auxiliary power source. Of the maximum of 27 attendant
consoles, 3 of the consoles can derive auxiliary power from the media gateway and through the
auxiliary cable located in the trunk/auxiliary field. Provide auxiliary power for a primary
attendant console through this cable so the console remains fully operational during short power
outages.
An attendant console can also derive auxiliary power from:
Individual 1151A1 or 1151A2 power supply
•
258A-type adapters
•
•
Bulk power supplies such as the 1145B2
A console's maximum distance from its auxiliary power source is:
800 feet (244 meters) for a 302A1
•
•
350 feet (107 meters) for a 301B1 and 302D
