§ 36.125 Local switching equipment—Category 3.
(a) Local switching equipment is included in account 2210. It comprises
all central office switching equipment not assigned other categories.
Examples of local switching equipment are basic switching train, toll
connecting trunk equipment, interlocal trunks, tandem trunks,
terminating senders used for toll completion, toll completing train,
call reverting equipment, weather and time of day service equipment,
and switching equipment at electronic analog or digital remote line
locations. Equipment used for the identification, recording and timing
of customer dialed charge traffic, or switched private line traffic
(e.g., transmitters, recorders, call identity indexers, perforators,
ticketers, detectors, mastertimes) switchboards used solely for
recording of calling telephone numbers in connection with customer
dialed charge traffic, or switched private line traffic (or both) is
included in this local switching category. Equipment provided and used
primarily for operator dialed toll or customer dialed charge traffic
except such equipment included in Category 2 Tandem Switching Equipment
is also included in this local switching category. This includes such
items as directors, translators, sender registers, out trunk selectors
and facilities for toll intercepting and digit absorption. Special
services switching equipment which primarily performs the switching
function for special services (e.g., switching equipment, TWX
concentrators and switchboards) is also included in this local
(1) Local office, as used in § 36.125, comprises one or more local
switching entities of the same equipment type (e.g., step-by-step, No.
5 Crossbar) in an individual location. A local switching entity
comprises that local central office equipment of the same type which
has a common intermediate distributing frame, market group or other
separately identifiable switching unit serving one or more prefixes
(2) A host/remote local switching complex is composed of an electronic
analog or digital host office and all of its remote locations. A
host/remote local switching complex is treated as one local office. The
current jurisdictional definition of an exchange will apply.
(3) Dial equipment minutes of use (DEM) is defined as the minutes of
holding time of the originating and terminating local switching
equipment. Holding time is defined in the Glossary.
(4) The interstate allocation factor is the percentage of local
switching investment apportioned to the interstate jurisdiction.
(5) The interstate DEM factor is the ratio of the interstate DEM to the
total DEM. A weighted interstate DEM factor is the product of
multiplying a weighting factor, as defined in paragraph (f) of this
section, to the interstate DEM factor. The state DEM factor is the
ratio of the state DEM to the total DEM.
(b) Beginning January 1, 1993, Category 3 investment for study areas
with 50,000 or more access lines is apportioned to the interstate
jurisdiction on the basis of the interstate DEM factor. Category 3
investment for study areas with 50,000 or more access lines is
apportioned to the state jurisdiction on the basis of the state DEM
(f) Beginning January 1, 1998, for study areas with fewer than 50,000
access lines, Category 3 investment is apportioned to the interstate
jurisdiction by the application of an interstate allocation factor that
is the lesser of either .85 or the sum of the interstate DEM factor
specified in paragraph (a)(5) of this section, and the difference
between the 1996 interstate DEM factor and the 1996 interstate DEM
factor multiplied by a weighting factor as determined by the table
below. The Category 3 investment that is not assigned to the interstate
jurisdiction pursuant to this paragraph is assigned to the state
Number of access lines in service in study area Weighting
50,001-or above 1.0
(g) For purposes of this section, an access line is a line that does
not include WATS access lines, special access lines or private lines.
(h) 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 3, Local
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 3, during the
twelve-month period ending December 31, 2000.
(i) Effective July 1, 2001, through December 31, 2024, all study areas
shall apportion costs in Category 3, Local Switching Equipment, among
the jurisdictions using relative dial equipment minutes of use for the
twelve-month period ending December 31, 2000.
(j) If the number of a study area's access lines increases such that,
under paragraph (f) of this section, the weighted interstate DEM factor
for 1997 or any successive year would be reduced, that lowered weighted
interstate DEM factor shall be applied to the study area's 1996
unweighted interstate DEM factor to derive a new local switching
support factor. If the number of a study area's access lines decreases
or has decreased such that, under paragraph (f) of this section, the
weighted interstate DEM factor for 2010 or any successive year would be
raised, that higher weighted interstate DEM factor shall be applied to
the study area's 1996 unweighted interstate DEM factor to derive a new
local switching support factor.
