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 13: Attendant console cabling distances .
Auxiliary power
!
CAUTION:
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.
