Incidence of Harm
Should terminal equipment or protective circuitry cause harm to the telephone
network, the telephone company shall, where practicable, notify the customer 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
discontinuance, the telephone company shall promptly notify the customer and will
be given the opportunity to correct the situation.
Additional Telephone Company Information

USOC RJ-31X telephone jack.

lines or to be used in conjunction with coin telephone service. Inter-connect rules
may vary from state to state.
Changes in Telephone Company Equipment of Facilities
The telephone company may make changes in its communications facilities,
equipment, operations or procedures, where such actions are reasonably required
and proper in its business. Should any such changes render the customer's terminal
equipment incompatible with the telephone company facilities the customer shall be
given adequate notice to the effect modifications to maintain uninterrupted service.
Ringer Equivalence Number (REN)
The REN is useful to determine the quantity of devices that you may connect to your
telephone line and still have all of those devices ring when your telephone number
is called. In most, but not all areas, the sum of the RENs of all devices connected to
one line should not exceed five (5.0). To be certain of the number of devices that you
may connect to your line, you may want to contact your local telephone company.
