  §  36.123   Operator systems equipment--Category 1.

   (a) Operator systems equipment is contained in Account 2220. It
   includes all types of manual telephone switchboards except tandem
   switchboards and those used solely for recording of calling telephone
   numbers in connection with customer dialed charge traffic. It includes
   all face equipment, terminating relay circuits of trunk and toll line
   circuits, cord circuits, cable turning sections, subscriber line
   equipment, associated toll connecting trunk equipment, number checking
   facilities, ticket distributing systems, calculagraphs, chief operator
   and other desks, operator chairs, and other such equipment.

   (1) Operator systems equipment is generally classified according to
   operating arrangements of which the following are typical:

   (i) Separate toll boards

   (ii) Separate local manual boards

   (iii) Combined local manual and toll boards

   (iv) Combined toll and DSA boards

   (v) Separate DSA and DSB boards

   (vi) Service observing boards

   (vii) Auxiliary service boards

   (viii) Traffic service positions

   (2) If switchboards as set forth in § 36.123(a) are of the key pulsing
   type, the cost of the key pulsing senders, link and trunk finder
   equipment is included with the switchboards.

   (3) DSB boards include the associated DSB dial equipment, such as link
   and sender equipment.

   (4) Traffic service position systems include the common control and
   trunk equipment in addition to the associated groups of positions
   wherever located.

   (5) Effective July 1, 2001, through June 30, 2011, study areas subject
   to price cap regulation, pursuant to § 61.41 of this chapter, shall
   assign the average balance of Account 2220, Operator Systems, to the
   categories/subcategories, as specified in § 36.123(a)(1), based on the
   relative percentage assignment of the average balance of Account 2220
   to these categories/subcategories during the twelve month period ending
   December 31, 2000.

   (6) Effective July 1, 2001 through June 30, 2011, all study areas shall
   apportion the costs assigned to the categories/subcategories, as
   specified in § 36.123(a)(1), among the jurisdictions using the relative
   use measurements for the twelve month period ending December 31, 2000
   for each of the categories/subcategories specified in § § 36.123 (b)
   through 36.123(e).

   (b) The cost of the following operator systems equipment is apportioned
   among the operations on the basis of the relative number of weighted
   standard work seconds handled at the switchboards under consideration.

   (1) The following types of switchboards at toll centers are generally
   apportioned individually:

   (i) Separate toll boards. These usually include outward, through and
   inward positions in separate lines and associated inward toll
   switchboard positions in line.

   (ii) Switchboards handling both local and toll, either combined or
   having segregated local and toll positions in the same line.

   (iii) Switchboards handling both toll and DSA, either combined or
   having segregated toll and DSA positions in the same line.

   (iv) Traffic service positions, including separately located groups of
   these positions when associated with a common basic control unit.

   (2) The following types of switchboards at toll centers are apportioned
   individually, or by groups of comparable types of boards for each
   exchange:

   (i) Separate local manual boards. This includes the local positions of
   manual boards where inward toll positions are in the same line.

   (ii) Separate DSA boards.

   (iii) Separate DSB boards.

   (3) Tributary boards may be treated individually if warranted or they
   may be treated on a group basis.

   (c) Auxiliary service boards generally handle rate and route,
   information, and intercept service at individual or joint positions.
   The cost of these boards is apportioned as follows:

   (1) The cost of separate directory assistance boards is apportioned
   among the operations on the basis of the relative number of weighted
   standard work seconds handled at the boards under consideration.
   Directory assistance weighted standard work seconds are apportioned
   among the operations on the basis of the classification of these
   weighted standard work seconds as follows:

   (i) Directory assistance weighted standard work seconds first are
   classified between calls received over toll directory assistance trunks
   from operators or customers and all other directory assistance calls.

   (ii) The directory assistance weighted standard work seconds of each
   type further are classified separately among the operations on the
   basis of an analysis of a representative sample of directory assistance
   calls of each type with reference to the locations of the calling and
   called stations for each call.

   (2) The cost of separate intercept boards and automated intercept
   systems in the study area is appportioned among the operations on the
   basis of the relative number of subscriber line minutes of use.

   (3) The cost of separate rate and route boards is generally included
   with the cost of the toll boards served and is apportioned with those
   boards.

   (4) Where more than one auxiliary service is handled at an auxiliary
   board, the cost of the board is apportioned among the auxiliary
   services on the basis of the relative number of weighted standard work
   seconds for each service. The cost of that part of the board allocated
   to each auxiliary service is apportioned among the operations in the
   same manner as for a separate auxiliary board.

   (d) The cost of joint exchange and toll service observing boards is
   first apportioned between exchange and toll use on the basis of the
   relative number of exchange and toll service observing units at these
   boards. The cost of separate toll service observing boards and the toll
   portion of joint service observing boards is apportioned between state
   and interstate operations on the basis of the relative number of toll
   minutes of use associated with the toll messages originating in the
   offices observed.

   (e) Traffic Service Position System (TSPS) investments are apportioned
   as follows:

   (1) Operator position investments are apportioned on the basis of the
   relative weighted standard work seconds for the entire TSPS complex.

   (2) Remote trunk arrangement (RTA) investments are apportioned on the
   basis of the relative processor real time (i.e., actual seconds)
   required to process TSPS traffic originating from the end offices
   served by each RTA.

   (3) The remaining investments at the central control location, such as
   the stored program control and memory, is apportioned on the basis of
   the relative processor real time (i.e., actual seconds) for the entire
   TSPS complex.

   [ 52 FR 17229 , May 6, 1987, as amended at  66 FR 33205 , June 21, 2001;  75 FR 30301 , June 1, 2010]
