User should not attempt to make such connections themselves,
but should contact the appropriate electric inspection authority,
or electrician, as appropriate.
The Northern Telecom Service Peripheral Module (SPM) system
complies with Part 68 of the FCC rules. On the inside door of the
cabinet is a label that contains, among other information, the FCC
registration number and Ringer Equivalence Number (REN) for this
equipment. If requested, this information must be provided to the
telephone company.
The Ringer Equivalence Number represents the electrical load that will
be applied to your telephone line once a Service Peripheral Module
modem port is connected to the network. The telephone line serving
your premises will not operate properly if the total ringer load exceeds
the capability of your telephone company central office equipment. If
you desire to know the total REN allowed for your line, call your
telephone company and they will inform you. Normally, no SPM modem
port should share the line with any other device.
If your Northern Telecom SPM causes harm to the telephone network,
the telephone company may disconnect your service temporarily. The
telephone company may ask you to disconnect the equipment from the
network until the problem has been corrected or may ask you to check
for any equipment malfunction. If possible, the telephone company will
notify you in advance of any loss of service; if not, you will be notified
as soon as possible. You will then be advised of your right to file a
complaint with the FCC.
Your telephone company may make changes in its facilities, equipment,
operations, or procedures that could affect proper operation of your
equipment. You will be given advanced notice of these changes in order
to maintain uninterrupted service.
If you experience problems with your Northern Telecom SPM
equipment, contact your Northern Telecom representative in the United
States for repair and warranty information. If you are unable to contact
your Northern Telecom representative, call 1-800-NORTHERN.
