Sec.  36.126   Circuit equipment—Category 4.

   (a) For the purpose of this section, the term “Circuit Equipment”
   encompasses the Radio Systems and Circuit Equipment contained in Accounts
   2230 through 2232 respectively. It includes central office equipment, other
   than switching equipment and automatic message recording equipment, which is
   used to derive communications transmission channels or which is used for the
   amplification, modulation, regeneration, testing, balancing or control of
   signals transmitted over communications transmission channels. Examples of
   circuit equipment in general use include:

   (1) Carrier telephone and telegraph system terminals.

   (2) Telephone and telegraph repeaters, termination sets, impedance
   compensators, pulse link repeaters, echo suppressors and other intermediate
   transmission amplification and balancing equipment except that included in
   switchboards.

   (3) Radio transmitters, receivers, repeaters and other radio central office
   equipment except message switching equipment associated with radio systems.

   (4) Composite ringers, line signaling and switching pad circuits.

   (5) Concentration equipment.

   (6) Composite sets and repeating coils.

   (7) Program transmission amplifiers, monitoring devices and volume
   indicators.

   (8) Testboards, test desks, repair desks and patch bays, including those
   provided for test and control, and for telegraph and transmission testing.

   (b) For apportionment among the operations, the cost of circuit equiment is
   assigned to the following subsidiary categories:

   (1) Exchange Circuit Equipment—Category 4.1.

   (i) Wideband Exchange Line Circuit Equipment—Category 4.11.

   (ii) Exchange Trunk Circuit Equipment (Wideband and Non-Wideband)—Category
   4.12.

   (iii) Exchange Line Circuit Equipment Excluding Wideband—Category 4.13.

   (2) Interexchange Circuit Equipment—Category 4.2.

   (i) Interexchange Circuit Equipment Furnished to Another Company for
   Interstate Use—Category 4.21.

   (ii) Interexchange Circuit Equipment Used for Wideband Services including
   Satellite and Earth Station Equipment used for Wideband Service—Category
   4.22.

   (iii) All Other Interexchange Circuit Equipment—Category 4.23.

   (3) Host/Remote Message Circuit Equipment—Category 4.3.

   (4) In addition, for the purpose of identifying and separating property
   associated with special services, circuit equipment included in Categories
   4.12 (other than wideband equipment) 4.13 and 4.23 is identified as either
   basic circuit equipment, i.e., equipment that performs functions necessary
   to provide and operate channels suitable for voice transmission (telephone
   grade channels), or special circuit equipment, i.e., equipment that is
   peculiar to special service circuits. Carrier telephone terminals and
   carrier telephone repeaters are examples of basic circuit equipment is
   general use, while audio program transmission amplifiers, bridges,
   monitoring devices and volume indicators, telegraph carrier terminals and
   telegraph repeaters are examples of special circuit equipment in general
   use. Cost of exchange circuit equipment included in Categories 4.12 and 4.13
   and the interexchange circuit equipment in Categories 4.21, 4.22 and 4.23
   are segregated between basic circuit equipment and special circuit equipment
   only at those locations where amounts of interexchange and exchange special
   circuit equipment are significant. Where such segregation is not made, the
   total costs in these categories are classified as basic circuit equipment.

   (5) Effective July 1, 2001, through June 30, 2006, study areas subject to
   price cap regulation, pursuant to  Sec. 61.41, shall assign the average balances
   of Accounts 2230 through 2232 to the categories/subcategories as specified
   in  Sec.  Sec. 36.126(b)(1) through (b)(4) based on the relative percentage assignment
   of the average balances of Accounts 2230 through 2232 costs to these
   categories/subcategories during the twelve month period ending December 31,
   2000.

   (c) Apportionment of Exchange Circuit Equipment Among the Operations:

   (1) Wideband Exchange Line Circuit Equipment—Category 4.11—The cost of
   exchange circuit equipment in this category is determined separately for
