5.1 FCC Rules And Regulations
This electronic key system complies with Federal Communications Commission (FCC) Rules, Part 68.
The FCC registration label on the DXP Plus contains the FCC registration number, the ringer
equivalence number, the model number, and the serial number or production date of the system.
Notification To Telephone Company
Unless a telephone operating company provides and installs the system, the telephone operating
company which provides the lines must be notified before a connection is made to them. The lines
(telephone numbers) involved, the FCC registration number, and the ringer equivalence number must be
provided to the telephone company. The FCC registration number and the ringer equivalence number of
this equipment are provided on the label attached to the common equipment. The user/installer is
required to notify the telephone company when final disconnection of this equipment from the telephone
company line occurs.
Compatibility With Telephone Network
When necessary, the telephone operating company provides information on the maximum number of
telephones or ringers that can be connected to one line, as well as any other applicable technical
information. The telephone operating company can temporarily discontinue service and make changes
which could affect the operation of this equipment. They must, however, provide adequate notice, in
writing, of any future equipment changes that would make the system incompatible.
Installation Requirements
Connection of the electronic key system to the telephone lines must be through a universal service order
code (USOC) outlet jack supplied by the telephone operating company. If the installation site does not
have the proper outlet, ask the telephone company business office to install one. The correct outlet jack
for this system is either a type RJ21X or type RJ14C.
Party Lines And Coin Lines
Local telephone company regulations may not permit connections to party lines and coin lines by
anyone except the telephone operating company.
Troubleshooting
If a service problem occurs, first try to determine if the trouble is in the on-site system or in the
telephone company equipment. Disconnect all equipment not owned by the telephone company.
If this corrects the problem, the faulty equipment must not be reconnected to the telephone line until the
problem has been corrected. Any trouble that causes improper operation of the telephone network may
require the telephone company to discontinue service to the trouble site after they notify the user of the
reason.
