INCIDENCE OF HARM Should terminal equipment or protective circuitry cause harm to
the telephone network, the telephone company shall, where practicable, notify the cus-
tomer that temporary disconnection of service may be required; however, where prior
notice is not practicable, the telephone company may temporarily discontinue service if
such action is deemed reasonable in the circumstances. In the case of such temporary dis-
continuance, the telephone company shall promptly notify the customer and will be given

telephone company facilities the customer shall be given adequate notice to the effect
modifications to maintain uninterrupted service.
