100. Each telephone utility furnishing switching service for service lines shall file with the Commission reasonable Rules and Regulations covering conditions under which the telephone performs switching service for subscribers. These rules may provide reasonable regulations covering the construction and the maintenance of such lines and equipment connected thereto as may be required to prevent an adverse effect on the general character of service rendered by the telephone utility. Such rules may provide for the discontinuance of service to an entire line requiring repairs, but only after written notice of intention to discontinue service has been given to the owner or owners thereof, which notice shall specify particular repairs necessary to make the service proper, and a reasonable period of time shall be allowed after the written notice before discontinuance of service within which to make the necessary corrections. However, if the condition of the line is such that it is actually adversely affecting the service to other customers of the utility, service may be discontinued immediately pending repairs to the service line and/or equipment. In case of disagreement relative to the extent of repairs necessary to place the line in satisfactory and serviceable condition, the matter shall be referred to the Commission.
