Importance Of Ringer Equivalence Number; Hearing Aid Compatibility - Nortel Meridian 1 Option 11C Planning And Installation Manual

Importance of Ringer Equivalence Number

The FCC regulation label includes the Ringer Equivalence Number (REN).
This number is a representation of the electrical load that will be applied to
your telephone line once the PBX is plugged into the wall jack. The telephone
line serving your premises will not operate properly if the total ringer load
exceeds the capability of the telephone company central office equipment.
That is, if too many ringers are connected to the line, there may be insufficient
energy to ring your system. If the ringer load is excessive, you may also have
difficulty dialing telephone numbers.
For more information about the total REN permitted for your telephone line,
contact your local telephone company. However, as a guideline, a total REN
of five should allow normal operation of your equipment.
If your Meridian 1 Option 11C equipment causes harm to the telephone
network, the telephone company may discontinue your service temporarily.
The telephone company may ask you to disconnect the equipment from the
network until the problem has been corrected, or you are sure that the
equipment is not malfunctioning. If it is possible, they will notify you in
advance of the pending disconnection. You will also 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 the proper operation of your
equipment. If they do, you will be given advance notice so as to give you an
opportunity to maintain uninterrupted service.
If you experience trouble with your Meridian 1 Option 11C equipment,
contact your authorized distributor or service center in the USA for repair or
warranty information. If you do not know how to contact your distributor, call
1-800-328-8800.
