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.

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.
