Sec.  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.
