Changes in Attestation Procedure for Plugs
and Jacks: (Name of applicant) attests that the
network interface plugs or jacks used on this
equipment comply with and will continue to
comply with the mechanical requirements
specified in Part 68, Sub-part F, specifically the
dimensions, tolerances and metallic plating
requirements. The compliance of these
connectors will be assured by purchase
specifications and incoming inspection.
Documentation of such specifications and/or
inspections will be provided to the FCC within 30
days of their request for the same.
Telephone Company Procedures: The goal of
the telephone company is to provide you with the
best service it can. In order to do this, it may
occasionally be necessary for them to make
changes in their equipment, operations or
procedures. If these changes might affect your
service or the operation of your equipment, the
telephone company will give you notice, in writing,
to allow you to make any changes necessary to
maintain uninterrupted service.
In certain circumstances, it may be necessary for
the telephone company to request information
from you concerning the equipment which you
have connected to your telephone line. Upon
request of the telephone company, provide the
FCC registration number and the ringer
equivalence number (REN); both of these items
are listed on the equipment label. The sum of all
of the REN ’s on your telephone lines should be
less than five in order to assure proper service
from the telephone company. In some cases, a
sum of five may not be useable on a given line.
Consult your telephone provider.
If Problems Arise: If any of your telephone
equipment is not operating properly, you should
immediately remove it from your telephone line,
as it may cause harm to the telephone network. If
the telephone company notes a problem, they
may temporarily discontinue service. When
practical, they will notify you in advance of this
disconnection. If advance notice is not feasible,
you will be notified as soon as possible.
