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
