§ 36.153 Assignment of Cable and Wire Facilities (C&WF) to categories.
(a) Cable consists of: Aerial cable, underground cable, buried cable,
submarine cable, deep sea cable and intrabuilding network cable. Where
an entire cable or aerial wire is assignable to one category, its cost
and quantity are, where practicable, directly assigned.
(1) Cable. (i) There are two basic methods for assigning the cost of
cable to the various categories. Both of them are on the basis of
conductor cross section. The methods are as follows:
(A) By section of cable, uniform as to makeup and relative use by
categories. From an analysis of cable engineering and assignment
records, determine in terms of equivalent gauge the number of pairs in
use or reserved, for each category. The corresponding percentages of
use, or reservation, are applied to the cost of the section of cable,
i.e., sheath meters times unit cost per meter, to obtain the cost
assignable to each category.
(B) By using equivalent pair kilometers, i.e., pair kilometers
expressed in terms of equivalent gauge. From an analysis of cable
engineering and assignment records, determine the equivalent pair
kilometers in use for each category by type of facility, e.g., quadded,
paired. The equivalent pair kilometers are then divided by a cable fill
factor to obtain the equivalent pair kilometers in plant. The total
equivalent pair kilometers in plant assigned to each category is
summarized by type of facility, e.g., quadded and paired, and priced at
appropriate average unit costs per equivalent pair kilometer in plant.
If desired, this study may be made in terms of circuit kilometers
rather than physical pair kilometers, with average cost and fill data
consistent with the basis of the facilities kilometer count.
(ii) In the assignment of the cost of cable under the two basic methods
described in § 36.153(a)(1)(i) consideration is given to the following:
(A) Method (A) described in § 36.153(a)(1)(i)(A) will probably be found
more desirable where there is a relatively small amount of cable of
variable make-up and use by categories. Conversely, method (B)
described in § 36.153(a)(1)(i)(B) will probably be more desirable where
there is a large amount of cable of variable make-up and use by
categories. However, in some cases a combination of both methods may be
(B) It will be desirable in some cases to determine the amount
assignable to a particular category by deducting from the total the sum
of the amounts assigned to all other categories.
(C) For use in the assignment of poles to categories, the equivalent
sheath kilometers of aerial cable assigned to each category are
determined. For convenience, these quantities are determined in
connection with assignment of cable costs.
(D) Where an entire cable is assignable to one category, its costs and
quantity are, where practicable, directly assigned.
(iii) For cables especially arranged for high-frequency transmission
such as shielded, disc-insulated and coaxial, recognition is given to
the additional costs which are charged to the high-frequency
(2) Cable Loading. (i) Methods for assigning the cost of loading coils,
cases, etc., to categories are comparable with those used in assigning
the associated cable to categories. Loading associated with cable which
is directly assigned to a given category is also directly assigned. The
remaining loading is assigned to categories in either of the following
(A) By an analysis of the use made of the loading facilities where a
loading coil case includes coils assignable to more than one category,
e.g., in the case of a single gauge uniformly loaded section, the
percentage used in the related cable assignment are applicable, or
(B) By pricing out each category by determining the pair meters of
loaded pairs assigned to each category and multiplying by the unit cost
per pair meter of loading by type.
(3) Other Cable Plant. (i) In view of the small amounts involved, the
cost of all protected terminals and gas pressure contactor terminals in
the toll cable subaccounts is assigned to the appropriate Interexchange
Cable & Wire Facilities categories. The cost of all other terminals in
the exchange and toll cable subaccounts is assigned to Exchange Cable
and Wire Facilities.
(b) Aerial Wire. (1) The cost of wire accounted for as exchange is
assigned to the appropriate Exchange Cable & Wire Facilities
categories. The cost of wire accounted for as toll, which is used for
exchange, is also assigned to the appropriate Exchange Cable & Wire
Facilities categories. The cost of the remaining wire accounted for as
toll is assigned to the appropriate Interexchange Cable & Wire
Facilities categories as described in § 36.156. For companies not
maintaining exchange and toll subaccounts, it is necessary to review
the plant records and identify wire plant by use. The cost of wire used
for providing circuits directly assignable to a category is assigned to
that category. The cost of wire used for providing circuit facilities
jointly used for exchange and interexchange lines is assigned to
categories on the basis of the relative number of circuit kilometers
(c) Poles and Antenna Supporting Structures. (1) In the assignment of
these costs, anchors, guys, crossarms, antenna supporting structure,
and right-of-way are included with the poles.
(2) Poles. (i) The cost of poles is assigned to categories based on the
ratio of the cost of poles to the total cost of aerial wire and aerial
(d) Conduit Systems. (1) The cost of conduit systems is assigned to
categories on the basis of the assignment of the cost of underground
