Sec. 90.49  Communications standby facilities.

    (a) Eligibility. A communications common carrier operating 
communications circuits that normally carry essential communication of 
such a nature that their disruption would endanger life or public 
property is eligible to hold authorizations for standby radio facilities 
for the transmission of messages only during periods when the normal 
circuits are inoperative due to circumstances beyond the control of the 
user. During such periods the radio facilities may be used to transmit 
any communication which would be carried by the regular circuit.
    (b) Special eligibility showing. Initial applications for 
authorization to operate a standby radio facility must include a 
statement describing radio communication facilities desired, the 
proposed method of operation, a description of the messages normally 
being carried, and an explanation of how their disruption will endanger 
life or public property.
