§ 51.319 Specific unbundling requirements.
(a) Local loops. An incumbent LEC shall provide a requesting
telecommunications carrier with nondiscriminatory access to the local loop
on an unbundled basis, in accordance with section 251(c)(3) of the Act and
this part and as set forth in paragraphs (a)(1) through (8) of this section.
The local loop network element is defined as a transmission facility between
a distribution frame (or its equivalent) in an incumbent LEC central office
and the loop demarcation point at an end-user customer premises. This
element includes all features, functions, and capabilities of such
transmission facility, including the network interface device. It also
includes all electronics, optronics, and intermediate devices (including
repeaters and load coils) used to establish the transmission path to the
end-user customer premises as well as any inside wire owned or controlled by
the incumbent LEC that is part of that transmission path.
(1) Copper loops. An incumbent LEC shall provide a requesting
telecommunications carrier with nondiscriminatory access to the copper loop
on an unbundled basis. A copper loop is a stand-alone local loop comprised
entirely of copper wire or cable. Copper loops include two-wire and
four-wire analog voice-grade copper loops, digital copper loops (e.g., DS0s
and integrated services digital network lines), as well as two-wire and
four-wire copper loops conditioned to transmit the digital signals needed to
provide digital subscriber line services, regardless of whether the copper
loops are in service or held as spares. The copper loop includes attached
electronics using time division multiplexing technology, but does not
include packet switching capabilities as defined in paragraph (a)(2)(i) of
this section. The availability of DS1 and DS3 copper loops is subject to the
requirements of paragraphs (a)(4) and (5) of this section.
(i) Line splitting. An incumbent LEC shall provide a requesting
telecommunications carrier that obtains an unbundled copper loop from the
incumbent LEC with the ability to engage in line splitting arrangements with
another competitive LEC using a splitter collocated at the central office
where the loop terminates into a distribution frame or its equivalent. Line
splitting is the process in which one competitive LEC provides narrowband
voice service over the low frequency portion of a copper loop and a second
competitive LEC provides digital subscriber line service over the high
frequency portion of that same loop. The high frequency portion of the loop
consists of the frequency range on the copper loop above the range that
carries analog circuit-switched voice transmissions. This portion of the
loop includes the features, functions, and capabilities of the loop that are
used to establish a complete transmission path on the high frequency range
between the incumbent LEC's distribution frame (or its equivalent) in its
central office and the demarcation point at the end-user customer premises,
and includes the high frequency portion of any inside wire owned or
controlled by the incumbent LEC.
(A) An incumbent LEC's obligation, under paragraph (a)(1)(i) of this
section, to provide a requesting telecommunications carrier with the ability
to engage in line splitting applies regardless of whether the carrier
providing voice service provides its own switching or obtains local circuit
switching from the incumbent LEC.
(B) An incumbent LEC must make all necessary network modifications,
including providing nondiscriminatory access to operations support systems
necessary for pre-ordering, ordering, provisioning, maintenance and repair,
and billing for loops used in line splitting arrangements.
(ii) Line conditioning. The incumbent LEC shall condition a copper loop at
the request of the carrier seeking access to a copper loop under paragraph
(a)(1) of this section or a copper subloop under paragraph (b) of this
section to ensure that the copper loop or copper subloop is suitable for
providing digital subscriber line services, whether or not the incumbent LEC
offers advanced services to the end-user customer on that copper loop or
copper subloop. If the incumbent LEC seeks compensation from the requesting
telecommunications carrier for line conditioning, the requesting
telecommunications carrier has the option of refusing, in whole or in part,
to have the line conditioned; and a requesting telecommunications carrier's
refusal of some or all aspects of line conditioning will not diminish any
right it may have, under paragraphs (a) and (b) of this section, to access
the copper loop or the copper subloop.
(A) Line conditioning is defined as the removal from a copper loop or copper
subloop of any device that could diminish the capability of the loop or
subloop to deliver high-speed switched wireline telecommunications
capability, including digital subscriber line service. Such devices include,
but are not limited to, bridge taps, load coils, low pass filters, and range
extenders.
(B) Incumbent LECs shall recover the costs of line conditioning from the
requesting telecommunications carrier in accordance with the Commission's
forward-looking pricing principles promulgated pursuant to section 252(d)(1)
of the Act and in compliance with rules governing nonrecurring costs in
§ 51.507(e).
(C) Insofar as it is technically feasible, the incumbent LEC shall test and
report troubles for all the features, functions, and capabilities of
conditioned copper lines, and may not restrict its testing to voice
transmission only.
(iii) Maintenance, repair, and testing. (A) An incumbent LEC shall provide,
on a nondiscriminatory basis, physical loop test access points to a
requesting telecommunications carrier at the splitter, through a
cross-connection to the requesting telecommunications carrier's collocation
space, or through a standardized interface, such as an intermediate
distribution frame or a test access server, for the purpose of testing,
maintaining, and repairing copper loops and copper subloops.
(B) An incumbent LEC seeking to utilize an alternative physical access
methodology may request approval to do so from the state commission, but
must show that the proposed alternative method is reasonable and
nondiscriminatory, and will not disadvantage a requesting telecommunications
carrier's ability to perform loop or service testing, maintenance, or
repair.
(iv) Control of the loop and splitter functionality. In situations where a
requesting telecommunications carrier is obtaining access to the high
frequency portion of a copper loop through a line splitting arrangement, the
incumbent LEC may maintain control over the loop and splitter equipment and
functions, and shall provide to the requesting telecommunications carrier
loop and splitter functionality that is compatible with any transmission
technology that the requesting telecommunications carrier seeks to deploy
using the high frequency portion of the loop, as defined in paragraph
(a)(1)(i) of this section, provided that such transmission technology is
presumed to be deployable pursuant to § 51.230.
(2) Hybrid loops. A hybrid loop is a local loop composed of both fiber optic
cable, usually in the feeder plant, and copper wire or cable, usually in the
distribution plant.
(i) Packet switching facilities, features, functions, and capabilities. An
incumbent LEC is not required to provide unbundled access to the packet
switched features, functions and capabilities of its hybrid loops. Packet
switching capability is the routing or forwarding of packets, frames, cells,
or other data units based on address or other routing information contained
in the packets, frames, cells or other data units, and the functions that
are performed by the digital subscriber line access multiplexers, including
but not limited to the ability to terminate an end-user customer's copper
loop (which includes both a low-band voice channel and a high-band data
channel, or solely a data channel); the ability to forward the voice
channels, if present, to a circuit switch or multiple circuit switches; the
ability to extract data units from the data channels on the loops; and the
ability to combine data units from multiple loops onto one or more trunks
connecting to a packet switch or packet switches.
(ii) Broadband services. When a requesting telecommunications carrier seeks
access to a hybrid loop for the provision of broadband services, an
incumbent LEC shall provide the requesting telecommunications carrier with
nondiscriminatory access to the time division multiplexing features,
functions, and capabilities of that hybrid loop, including DS1 or DS3
capacity (where impairment has been found to exist), on an unbundled basis
to establish a complete transmission path between the incumbent LEC's
central office and an end user's customer premises. This access shall
include access to all features, functions, and capabilities of the hybrid
loop that are not used to transmit packetized information.
(iii) Narrowband services. When a requesting telecommunications carrier
seeks access to a hybrid loop for the provision of narrowband services, the
incumbent LEC may either:
(A) Provide nondiscriminatory access, on an unbundled basis, to an entire
hybrid loop capable of voice-grade service (i.e., equivalent to DS0
capacity), using time division multiplexing technology; or
(B) Provide nondiscriminatory access to a spare home-run copper loop serving
that customer on an unbundled basis.
(3) Fiber loops—(i) Definitions—(A) Fiber-to-the-home loops. A
fiber-to-the-home loop is a local loop consisting entirely of fiber optic
cable, whether dark or lit, serving an end user's customer premises or, in
the case of predominantly residential multiple dwelling units (MDUs), a
fiber optic cable, whether dark or lit, that extends to the multiunit
premises' minimum point of entry (MPOE).
(B) Fiber-to-the-curb loops. A fiber-to-the-curb loop is a local loop
consisting of fiber optic cable connecting to a copper distribution plant
that is not more than 500 feet from the customer's premises or, in the case
of predominantly residential MDUs, not more than 500 feet from the MDU's
MPOE. The fiber optic cable in a fiber-to-the-curb loop must connect to a
copper distribution plant at a serving area interface from which every other
copper distribution subloop also is not more than 500 feet from the
respective customer's premises.
(ii) New builds. An incumbent LEC is not required to provide
nondiscriminatory access to a fiber-to-the-home loop or a fiber-to-the-curb
loop on an unbundled basis when the incumbent LEC deploys such a loop to an
end user's customer premises that previously has not been served by any loop
facility.
(iii) Overbuilds. An incumbent LEC is not required to provide
nondiscriminatory access to a fiber-to-the-home loop or a fiber-to-the-curb
loop on an unbundled basis when the incumbent LEC has deployed such a loop
parallel to, or in replacement of, an existing copper loop facility, except
that:
(A) The incumbent LEC must maintain the existing copper loop connected to
the particular customer premises after deploying the fiber-to-the-home loop
or the fiber-to-the-curb loop and provide nondiscriminatory access to that
copper loop on an unbundled basis unless the incumbent LEC retires the
copper loops pursuant to paragraph (a)(3)(iv) of this section.
(B) An incumbent LEC that maintains the existing copper loops pursuant to
paragraph (a)(3)(iii)(A) of this section need not incur any expenses to
ensure that the existing copper loop remains capable of transmitting signals
prior to receiving a request for access pursuant to that paragraph, in which
case the incumbent LEC shall restore the copper loop to serviceable
condition upon request.
(C) An incumbent LEC that retires the copper loop pursuant to paragraph
(a)(3)(iv) of this section shall provide nondiscriminatory access to a 64
kilobits per second transmission path capable of voice grade service over
the fiber-to-the-home loop or fiber-to-the-curb loop on an unbundled basis.
(iv) Retirement of copper loops or copper subloops. Prior to retiring any
copper loop or copper subloop that has been replaced with a
fiber-to-the-home loop or a fiber-to-the-curb loop, an incumbent LEC must
comply with:
(A) The network disclosure requirements set forth in section 251(c)(5) of
the Act and in § 51.325 through § 51.335; and
(B) Any applicable state requirements.
(4) DS1 loops. (i) Subject to the cap described in paragraph (a)(4)(ii) of
this section, an incumbent LEC shall provide a requesting telecommunications
carrier with nondiscriminatory access to a DS1 loop on an unbundled basis to
any building not served by a wire center with at least 60,000 business lines
and at least four fiber-based collocators. Once a wire center exceeds both
of these thresholds, no future DS1 loop unbundling will be required in that
wire center. A DS1 loop is a digital local loop having a total digital
signal speed of 1.544 megabytes per second. DS1 loops include, but are not
limited to, two-wire and four-wire copper loops capable of providing
high-bit rate digital subscriber line services, including T1 services.
(ii) Cap on unbundled DS1 loop circuits. A requesting telecommunications
carrier may obtain a maximum of ten unbundled DS1 loops to any single
building in which DS1 loops are available as unbundled loops.
(5) DS3 loops. (i) Subject to the cap described in paragraph (a)(5)(ii) of
this section, an incumbent LEC shall provide a requesting telecommunications
carrier with nondiscriminatory access to a DS3 loop on an unbundled basis to
any building not served by a wire center with at least 38,000 business lines
and at least four fiber-based collocators. Once a wire center exceeds both
of these thresholds, no future DS3 loop unbundling will be required in that
wire center. A DS3 loop is a digital local loop having a total digital
signal speed of 44.736 megabytes per second.
(ii) Cap on unbundled DS3 loop circuits. A requesting telecommunications
carrier may obtain a maximum of a single unbundled DS3 loop to any single
building in which DS3 loops are available as unbundled loops.
(6) Dark fiber loops. An incumbent LEC is not required to provide requesting
telecommunications carriers with access to a dark fiber loop on an unbundled
basis. Dark fiber is fiber within an existing fiber optic cable that has not
yet been activated through optronics to render it capable of carrying
communications services.
(7) Routine network modifications. (i) An incumbent LEC shall make all
routine network modifications to unbundled loop facilities used by
requesting telecommunications carriers where the requested loop facility has
already been constructed. An incumbent LEC shall perform these routine
network modifications to unbundled loop facilities in a nondiscriminatory
fashion, without regard to whether the loop facility being accessed was
constructed on behalf, or in accordance with the specifications, of any
carrier.
(ii) A routine network modification is an activity that the incumbent LEC
regularly undertakes for its own customers. Routine network modifications
include, but are not limited to, rearranging or splicing of cable; adding an
equipment case; adding a doubler or repeater; adding a smart jack;
installing a repeater shelf; adding a line card; deploying a new multiplexer
or reconfiguring an existing multiplexer; and attaching electronic and other
equipment that the incumbent LEC ordinarily attaches to a DS1 loop to
activate such loop for its own customer. Routine network modifications may
entail activities such as accessing manholes, deploying bucket trucks to
reach aerial cable, and installing equipment casings. Routine network
modifications do not include the construction of a new loop, or the
installation of new aerial or buried cable for a requesting
telecommunications carrier.
(8) Engineering policies, practices, and procedures. An incumbent LEC shall
not engineer the transmission capabilities of its network in a manner, or
engage in any policy, practice, or procedure, that disrupts or degrades
access to a local loop or subloop, including the time division
multiplexing-based features, functions, and capabilities of a hybrid loop,
for which a requesting telecommunications carrier may obtain or has obtained
access pursuant to paragraph (a) of this section.
(b) Subloops. An incumbent LEC shall provide a requesting telecommunications
carrier with nondiscriminatory access to subloops on an unbundled basis in
accordance with section 251(c)(3) of the Act and this part and as set forth
in paragraph (b) of this section.
(1) Copper subloops. An incumbent LEC shall provide a requesting
telecommunications carrier with nondiscriminatory access to a copper subloop
on an unbundled basis. A copper subloop is a portion of a copper loop, or
hybrid loop, comprised entirely of copper wire or copper cable that acts as
a transmission facility between any point of technically feasible access in
an incumbent LEC's outside plant, including inside wire owned or controlled
by the incumbent LEC, and the end-user customer premises. A copper subloop
includes all intermediate devices (including repeaters and load coils) used
to establish a transmission path between a point of technically feasible
access and the demarcation point at the end-user customer premises, and
includes the features, functions, and capabilities of the copper loop.
Copper subloops include two-wire and four-wire analog voice-grade subloops
as well as two-wire and four-wire subloops conditioned to transmit the
digital signals needed to provide digital subscriber line services,
regardless of whether the subloops are in service or held as spares.
(i) Point of technically feasible access. A point of technically feasible
access is any point in the incumbent LEC's outside plant where a technician
can access the copper wire within a cable without removing a splice case.
Such points include, but are not limited to, a pole or pedestal, the serving
area interface, the network interface device, the minimum point of entry,
any remote terminal, and the feeder/distribution interface. An incumbent LEC
shall, upon a site-specific request, provide access to a copper subloop at a
splice near a remote terminal. The incumbent LEC shall be compensated for
providing this access in accordance with § § 51.501 through 51.515.
(ii) Rules for collocation. Access to the copper subloop is subject to the
Commission's collocation rules at § § 51.321 and 51.323.
(2) Subloops for access to multiunit premises wiring. An incumbent LEC shall
provide a requesting telecommunications carrier with nondiscriminatory
access to the subloop for access to multiunit premises wiring on an
unbundled basis regardless of the capacity level or type of loop that the
requesting telecommunications carrier seeks to provision for its customer.
The subloop for access to multiunit premises wiring is defined as any
portion of the loop that it is technically feasible to access at a terminal
in the incumbent LEC's outside plant at or near a multiunit premises. One
category of this subloop is inside wire, which is defined for purposes of
this section as all loop plant owned or controlled by the incumbent LEC at a
multiunit customer premises between the minimum point of entry as defined in
§ 68.105 of this chapter and the point of demarcation of the incumbent LEC's
network as defined in § 68.3 of this chapter.
(i) Point of technically feasible access. A point of technically feasible
access is any point in the incumbent LEC's outside plant at or near a
multiunit premises where a technician can access the wire or fiber within
the cable without removing a splice case to reach the wire or fiber within
to access the wiring in the multiunit premises. Such points include, but are
not limited to, a pole or pedestal, the network interface device, the
minimum point of entry, the single point of interconnection, and the
feeder/distribution interface.
(ii) Single point of interconnection. Upon notification by a requesting
telecommunications carrier that it requests interconnection at a multiunit
premises where the incumbent LEC owns, controls, or leases wiring, the
incumbent LEC shall provide a single point of interconnection that is
suitable for use by multiple carriers. This obligation is in addition to the
incumbent LEC's obligations, under paragraph (b)(2) of this section, to
provide nondiscriminatory access to a subloop for access to multiunit
premises wiring, including any inside wire, at any technically feasible
point. If the parties are unable to negotiate rates, terms, and conditions
under which the incumbent LEC will provide this single point of
interconnection, then any issues in dispute regarding this obligation shall
be resolved in state proceedings under section 252 of the Act.
(3) Other subloop provisions—(i) Technical feasibility. If parties are
unable to reach agreement through voluntary negotiations as to whether it is
technically feasible, or whether sufficient space is available, to unbundle
a copper subloop or subloop for access to multiunit premises wiring at the
point where a telecommunications carrier requests, the incumbent LEC shall
have the burden of demonstrating to the state commission, in state
proceedings under section 252 of the Act, that there is not sufficient space
available, or that it is not technically feasible to unbundle the subloop at
the point requested.
(ii) Best practices. Once one state commission has determined that it is
technically feasible to unbundle subloops at a designated point, an
incumbent LEC in any state shall have the burden of demonstrating to the
state commission, in state proceedings under section 252 of the Act, that it
is not technically feasible, or that sufficient space is not available, to
unbundle its own loops at such a point.
(c) Network interface device. Apart from its obligation to provide the
network interface device functionality as part of an unbundled loop or
subloop, an incumbent LEC also shall provide nondiscriminatory access to the
network interface device on an unbundled basis, in accordance with section
251(c)(3) of the Act and this part. The network interface device element is
a stand-alone network element and is defined as any means of interconnection
of customer premises wiring to the incumbent LEC's distribution plant, such
as a cross-connect device used for that purpose. An incumbent LEC shall
permit a requesting telecommunications carrier to connect its own loop
facilities to on-premises wiring through the incumbent LEC's network
interface device, or at any other technically feasible point.
(d) Dedicated transport. An incumbent LEC shall provide a requesting
telecommunications carrier with nondiscriminatory access to dedicated
transport on an unbundled basis, in accordance with section 251(c)(3) of the
Act and this part, as set forth in paragraphs (d) through (d)(4) of this
section. A “route” is a transmission path between one of an incumbent LEC's
wire centers or switches and another of the incumbent LEC's wire centers or
switches. A route between two points (e.g., wire center or switch “A” and
wire center or switch “Z”) may pass through one or more intermediate wire
centers or switches (e.g., wire center or switch “X”). Transmission paths
between identical end points (e.g., wire center or switch “A” and wire
center or switch “Z”) are the same “route,” irrespective of whether they
pass through the same intermediate wire centers or switches, if any.
(1) Definition. For purposes of this section, dedicated transport includes
incumbent LEC transmission facilities between wire centers or switches owned
by incumbent LECs, or between wire centers or switches owned by incumbent
LECs and switches owned by requesting telecommunications carriers,
including, but not limited to, DS1-, DS3-, and OCn-capacity level services,
as well as dark fiber, dedicated to a particular customer or carrier.
(2) Availability.
(i) Entrance facilities. An incumbent LEC is not obligated to provide a
requesting carrier with unbundled access to dedicated transport that does
not connect a pair of incumbent LEC wire centers.
(ii) Dedicated DS1 transport. Dedicated DS1 transport shall be made
available to requesting carriers on an unbundled basis as set forth in
paragraphs (d)(2)(ii)(A) and (B) of this section. Dedicated DS1 transport
consists of incumbent LEC interoffice transmission facilities that have a
total digital signal speed of 1.544 megabytes per second and are dedicated
to a particular customer or carrier.
(A) General availability of DS1 transport. Incumbent LECs shall unbundle DS1
transport between any pair of incumbent LEC wire centers except where,
through application of tier classifications described in paragraph (d)(3) of
this section, both wire centers defining the route are Tier 1 wire centers.
As such, an incumbent LEC must unbundle DS1 transport if a wire center at
either end of a requested route is not a Tier 1 wire center, or if neither
is a Tier 1 wire center.
(B) Cap on unbundled DS1 transport circuits. A requesting telecommunications
carrier may obtain a maximum of ten unbundled DS1 dedicated transport
circuits on each route where DS1 dedicated transport is available on an
unbundled basis.
(iii) Dedicated DS3 transport. Dedicated DS3 transport shall be made
available to requesting carriers on an unbundled basis as set forth in
paragraphs (d)(2)(iii)(A) and(B) of this section. Dedicated DS3 transport
consists of incumbent LEC interoffice transmission facilities that have a
total digital signal speed of 44.736 megabytes per second and are dedicated
to a particular customer or carrier.
(A) General availability of DS3 transport. Incumbent LECs shall unbundle DS3
transport between any pair of incumbent LEC wire centers except where,
through application of tier classifications described in paragraph (d)(3) of
this section, both wire centers defining the route are either Tier 1 or Tier
2 wire centers. As such, an incumbent LEC must unbundle DS3 transport if a
wire center on either end of a requested route is a Tier 3 wire center.
(B) Cap on unbundled DS3 transport circuits. A requesting telecommunications
carrier may obtain a maximum of 12 unbundled DS3 dedicated transport
circuits on each route where DS3 dedicated transport is available on an
unbundled basis.
(iv) Dark fiber transport. Dark fiber transport consists of unactivated
optical interoffice transmission facilities. Incumbent LECs shall unbundle
dark fiber transport between any pair of incumbent LEC wire centers except
where, through application of tier classifications described in paragraph
(d)(3) of this section, both wire centers defining the route are either Tier
1 or Tier 2 wire centers. An incumbent LEC must unbundle dark fiber
transport if a wire center on either end of a requested route is a Tier 3
wire center.
(3) Wire center tier structure. For purposes of this section, incumbent LEC
wire centers shall be classified into three tiers, defined as follows:
(i) Tier 1 wire centers are those incumbent LEC wire centers that contain at
least four fiber-based collocators, at least 38,000 business lines, or both.
Tier 1 wire centers also are those incumbent LEC tandem switching locations
that have no line-side switching facilities, but nevertheless serve as a
point of traffic aggregation accessible by competitive LECs. Once a wire
center is determined to be a Tier 1 wire center, that wire center is not
subject to later reclassification as a Tier 2 or Tier 3 wire center.
(ii) Tier 2 wire centers are those incumbent LEC wire centers that are not
Tier 1 wire centers, but contain at least 3 fiber-based collocators, at
least 24,000 business lines, or both. Once a wire center is determined to be
a Tier 2 wire center, that wire center is not subject to later
reclassification as a Tier 3 wire center.
(iii) Tier 3 wire centers are those incumbent LEC wire centers that do not
meet the criteria for Tier 1 or Tier 2 wire centers.
(4) Routine network modifications. (i) An incumbent LEC shall make all
routine network modifications to unbundled dedicated transport facilities
used by requesting telecommunications carriers where the requested dedicated
transport facilities have already been constructed. An incumbent LEC shall
perform all routine network modifications to unbundled dedicated transport
facilities in a nondiscriminatory fashion, without regard to whether the
facility being accessed was constructed on behalf, or in accordance with the
specifications, of any carrier.
(ii) A routine network modification is an activity that the incumbent LEC
regularly undertakes for its own customers. Routine network modifications
include, but are not limited to, rearranging or splicing of cable; adding an
equipment case; adding a doubler or repeater; installing a repeater shelf;
and deploying a new multiplexer or reconfiguring an existing multiplexer.
They also include activities needed to enable a requesting
telecommunications carrier to light a dark fiber transport facility. Routine
network modifications may entail activities such as accessing manholes,
deploying bucket trucks to reach aerial cable, and installing equipment
casings. Routine network modifications do not include the installation of
new aerial or buried cable for a requesting telecommunications carrier.
(e) 911 and E911 databases. An incumbent LEC shall provide a requesting
telecommunications carrier with nondiscriminatory access to 911 and E911
databases on an unbundled basis, in accordance with section 251(c)(3) of the
Act and this part.
(f) Operations support systems. An incumbent LEC shall provide a requesting
telecommunications carrier with nondiscriminatory access to operations
support systems on an unbundled basis, in accordance with section 251(c)(3)
of the Act and this part. Operations support system functions consist of
pre-ordering, ordering, provisioning, maintenance and repair, and billing
functions supported by an incumbent LEC's databases and information. An
incumbent LEC, as part of its duty to provide access to the pre-ordering
function, shall provide the requesting telecommunications carrier with
nondiscriminatory access to the same detailed information about the loop
that is available to the incumbent LEC.
