Attendant console cabling distances, local
and phantom power
A console’s maximum distance from the media gateway is limited. The maximum distance for a 302D
console is as shown in Table 20, Attendant console cabling distances,
on page 208.
Auxiliary power
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 1151B1 or 1151B2 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
