The Attendant Console’s (AC) maximum distance from the system is limited.
See Table 1-16.
Auxiliary power
The nonessential functions of an AC and its optional 26A1 or 24A1 selector
console derive power from an auxiliary power source. During short power
outages, provide auxiliary power for an AC through this cable so the console
remains fully operational.
NOTE:
Only 1 console can derive auxiliary power from the system and through the
auxiliary cable located in the trunk/auxiliary field.
A console’s maximum distance from its auxiliary power source is:
■ 800 feet (244 m) for a 302A1
■ 350 feet (107 m) for a 301B1 and 302C1
An AC can also derive auxiliary power from:
■ Individual 1151A or 1151A2 power supply
■ MSP-1 power supply
■ 258A-type adapters
■ Bulk power supplies such as the 1145A1
