§  68.110   Compatibility of the public switched telephone network and
terminal equipment.

   (a) Availability of interface information. Technical information
   concerning interface parameters not specified by the technical criteria
   published by the Administrative Council for Terminal Attachments, that
   are needed to permit terminal equipment to operate in a manner
   compatible with the communications facilities of a provider of wireline
   telecommunications, shall be provided by the provider of wireline
   telecommunications upon request.

   (b) Changes in the facilities, equipment, operations, or procedures of
   a provider of wireline telecommunications. A provider of wireline
   telecommunications may make changes in its communications facilities,
   equipment, operations or procedures, where such action is reasonably
   required in the operation of its business and is not inconsistent with
   the rules and regulations in this part. If such changes can be
   reasonably expected to render any customer's terminal equipment
   incompatible with the communications facilities of the provider of
   wireline telecommunications, or require modification or alteration of
   such terminal equipment, or otherwise materially affect its use or
   performance, the customer shall be given adequate notice in writing, to
   allow the customer an opportunity to maintain uninterrupted service.

   (c) Availability of inside wiring information. Any available technical
   information concerning wiring on the customer side of the demarcation
   point, including copies of existing schematic diagrams and service
   records, shall be provided by the provider of wireline
   telecommunications upon request of the building owner or agent thereof.
   The provider of wireline telecommunications may charge the building
   owner a reasonable fee for this service, which shall not exceed the
   cost involved in locating and copying the documents. In the
   alternative, the provider of wireline telecommunications may make these
   documents available for review and copying by the building owner. In
   this case, the provider of wireline telecommunications may charge a
   reasonable fee, which shall not exceed the cost involved in making the
   documents available, and may also require the building owner to pay a
   deposit to guarantee the documents' return.
