§ 36.124 Tandem switching equipment—Category 2.
(a) Tandem switching equipment is contained in Account 2210. It
includes all switching equipment in a tandem central office, including
any associated tandem switchboard positions and any intertoll switching
equipment. Intertoll switching equipment includes switching equipment
used for the interconnection of message toll telephone circuits with
each other or with local or tandem telephone central office trunks,
intertoll dial selector equipment, or intertoll trunk equipment in No.
5 type electronic offices. Equipment, including switchboards used for
recording of calling telephone numbers and other billing information in
connection with customer dialed charge traffic is included with Local
Switching Equipment—Category 3.
(1) At toll center toll offices, intertoll switching equipment
comprises equipment in the toll office used in the interconnection of:
Toll center to toll center circuits; toll center to tributary circuits;
tributary to tributary circuits; toll center to tandem circuits or in
the interconnection of the aforementioned types of circuits with trunks
to local offices in the toll center city, i.e., interconnection with
toll switching trunks, operator trunks, information trunks, testing
trunks, etc. Equipment associated with the local office end of such
trunks is included with local switching equipment or switchboard
categories as appropriate.
(2) At tributary offices, this category includes intertoll switching
equipment similar to that at toll center toll offices if it is used in
the interconnection of: Tributary to tributary circuits; tributary to
subtributary circuits; subtributary to subtributary circuits; toll
center to subtributary circuits; or if it is used jointly in the
interconnection of any of the aforementioned types of circuits and in
the interconnection of such toll circuits with trunk circuits for the
handling of traffic terminating in the tributary office. Where
comparable equipment has no joint use but is used only for the handling
of traffic terminating in the tributary office, it is included in the
local switching equipment category.
(3) At all switching entities, this category includes intertoll
switching equipment similar to that at toll center toll offices if it
is used in the interconnection of switched private line trunks or TWX
switching plant trunks when these functions are in addition to the
message telephone switching function. Switching entities wholly
dedicated to switching of special services are assigned to Category
3—Local Switching Equipment.
(b) The costs of central office equipment items assigned this category
are to be directly assigned when possible. When direct assignment is
not possible the costs shall be apportioned among the operations on the
basis of the relative number of study area minutes of use of this
(c) Effective July 1, 2001, through December 31, 2024, study areas
subject to price cap regulation, pursuant to § 61.41 of this chapter,
shall assign the average balance of Account 2210 to Category 2, Tandem
Switching Equipment based on the relative percentage assignment of the
average balance of Account 2210 (or, if Accounts 2211, 2212, and 2215
were required to be maintained at the applicable time, the average
balances of Accounts 2211, 2212, and 2215) to Category 2, Tandem
Switching Equipment during the twelve-month period ending December 31,
(d) Effective July 1, 2001, through December 31, 2024, all study areas
shall apportion costs in Category 2, Tandem Switching Equipment, among
the jurisdictions using the relative number of study area minutes of
use, as specified in paragraph (b) of this section, for the
twelve-month period ending December 31, 2000. Direct assignment of any
subcategory of Category 2 Tandem Switching Equipment between
jurisdictions shall be updated annually.
