Specific Instructions
I.

Introduction and Background.

Competitive eligible telecommunications carriers (CETCs) are eligible to receive High Cost support
if they serve lines in an incumbent carrier’s service area, and that incumbent carrier receives High
Cost support. CETCs are eligible to receive the same per-line support amount received by the
incumbent carrier in whose study area the CETC serves lines. Unlike the incumbent carriers,
CETCs will use FCC Form 525 to submit their line count data to USAC.
II.

The Carrier or the Carrier’s Agent May File This Form.

As a CETC, you may choose to complete FCC Form 525 and submit it to USAC. Alternatively,
you may choose to designate an agent to file FCC Form 525 on your behalf. Please note that, if
you choose to designate an agent to complete and submit FCC Form 525 on your behalf, an
authorized officer or employee of your company must advise USAC of the identity of your agent,
and certify that the actual line count data provided to your authorized agent is accurate to the best of
his/her knowledge. Your authorized agent must:
1)
certify that he/she is authorized to submit the information on behalf of the
reporting CETC;
2)
certify that the line count data provided on the form is based on actual line count
data received from the reporting CETC;
3)
certify that the information on the form is accurate to the best of the agent’s
knowledge; and
4)
provide copies of the line count filing to the reporting CETC within 15 days.
Specific instructions for complying with these steps are set forth below on pages 14 and 15 of these
instructions.
III.

CETCs Complete Different Worksheet Areas in This Form Consistent with the
Disaggregation Path Selected by the Incumbent Carrier in Whose Service Area the CETC
Serves Lines.

Path 1: If the incumbent carrier in whose service area a CETC serves lines elects not to disaggregate
and target support, they are a Path 1 carrier. For lines served by CETCs in Path 1 incumbent carrier
service areas, CETCs shall report lines at a study area level.
Path 2 & 3: Alternately, if the incumbent carrier in whose service area a CETC serves lines elects to
disaggregate and target support, CETCs must provide information consistent with the approved Path
2 or Path 3 disaggregation plan elected by the incumbent carrier.
IV.

Line Count Information.

CETCs must file the number of working loops served in the service area of an incumbent carrier,
disaggregated by the incumbent carrier’s cost zones, if applicable, for High Cost Loop (HCL),
Local Switching Support (LSS), Long Term Support (LTS), and Interstate Common Line Support
(ICLS). ICLS will also require the loops to be reported by customer class as further described
2

Instructions for Completing FCC Form 525
Competitive Carrier Line Count Report
July 2018

below. For Interstate Access Support (IAS), CETCs must file the number of working loops served
in the service area of an incumbent carrier by Unbundled Network Element (UNE) zone and
customer class. Working loops provided by CETCs in service areas of non-rural incumbents
receiving High Cost Model (HCM) support must be filed by wire center or other methodology as
determined by the state regulatory authority. The two customer classes for the purposes of ICLS and
IAS and the CETC form are:
Residential and single-line business access lines in service; and
Multi-line business access lines in service.
V.

Effect of Disaggregation on Line Count Reporting Requirements.

If an incumbent has established disaggregation zones within its study area pursuant to 47 C.F.R.
§54.315, CETCs must report the actual line count data for each disaggregation zone. Reporting
worksheets affected by disaggregation are designated by each component as follows:
HCL and LSS (Page 2)
ICLS (Page 3)
CETCs are bound by the disaggregation path chosen by the incumbent carrier in whose study area
the CETC serves.
VI.

When Must CETCs File Line Count Reports?

CETCs must file quarterly line count reports according to the following schedule to be eligible to
receive:

Page 1 – General Information/Competitive Carrier High Cost Data Submission
Item 1, Quarterly Submission Date: Provide the completion date of the form. This may be different
from the quarter end filing date for which support is being requested in Item 12.
Item 2, USAC Service Provider Identification Number (SPIN): Provide the nine-digit SPIN
assigned by USAC. Your company SPIN was assigned through your initial submission of FCC
Form 498. If you do not know your SPIN, you may contact USAC’s Billing, Collections, and
Disbursements Call Center at 1-888-641-8722.
Item 3, Company Study Area Code (SAC): USAC assigns CETCs a SAC for each jurisdiction
served. Please be sure to file a separate Competitive Carrier form for each jurisdiction or study area
in which you serve. If you are a CETC and do not know your SAC, please contact USAC’s High
Cost Customer Service Center at 1-877-877-4925 for assistance.
Item 4, Study Area Name: Provide the standard name that you use to identify your study area.
Typically, the name is the same as your company name.
Item 5, Company Legal Name: Provide the name of your company as it appears on your ETC
designation Order from the state Public Service Commission (PSC) or the Federal Communications
Commission (FCC)
Item 6, Filer 499 ID: Provide the same ID that this carrier provided on FCC Form 499. This code is
assigned by the Commission’s Data Collection Agent after a company files its first FCC Form 499A. Filer 499 IDs for current filers can be found at http://gullfoss2.fcc.gov/cib/form499/499a.cfm or
in the FCC report Telecommunications Provider Locator, which is available on the Commission’s
web site at http://www.fcc.gov/wcb/iatd/stats.html. If you are having difficulty finding this ID, call

your business address has changed from your previous data submissions, please indicate this by
checking the box provided.
Item 8, Contact Name: Provide the name of the individual that prepared the data submission for
your company. Providing this information will assist USAC in resolving any issues or questions
that arise from the data submission.
Item 9, Title: Provide position title of contact name listed in Item 8.
Item 10, Telephone Number: Provide the telephone number of the individual that prepared the data
submission for your company. Providing this information will assist USAC in resolving any issues
or questions that arise from the data submission.
Item 11, E-mail Address: Provide the e-mail address of the individual that prepared the data
submission for your company. Providing this information will assist USAC in resolving any issues
or questions that arise from the data submission.
Item 12, High Cost Mechanism Selection Box: Please mark the boxes for the corresponding
mechanisms for which you are requesting support. CETCs are eligible to receive support for the
same mechanisms that the incumbent ETC, in whose study area the CETC serves lines, receives
support. Please be aware that on a study area basis, a CETC will be eligible for HCL OR HCM.
Additionally, a CETC will be eligible for IAS OR ICLS. The incumbent ETC profile will dictate
which of these mechanisms the CETC can receive. The incumbent’s status as a rural or non-rural
carrier, rate-of-return or price cap carrier will dictate the support mechanisms for which CETCs will
be eligible to receive support.
Item 13, Lines Reported as of: Provide the date the lines were reported as of for each of the
mechanisms in which you are requesting support. Please see Section VI. for reporting as of dates
for each mechanism.
For example, you would enter 12/31/2002 for your line count data that is reported in the July 31,
2003 line count filing, because the report contains lines served as of December 31, 2002.
Item 14, Type of Filing: Mark the “Type of Filing” column(s) accordingly. For original data
submissions please place a mark in the “Original” column. Where CETCs require corrections to
previously submitted information, a mark should be placed in the “Revision” column. In the event
that a CETC files a “Revision”, please be sure to double check the “Lines Reported as of” date for
accuracy so that USAC can adjust the appropriate time frames.
Item 15, Worksheet to Complete: Use this column as a reference guide for verifying which
worksheet(s) need to be completed for proper filing, based on requested support mechanism
selected in fields #13 and #14.

information will be provided. This information can also be found in the High Cost appendices,
located on USAC’s web site under FCC Filings.
Reporting Lines for Incumbent Carriers that Elected Path 1 Disaggregation:
Column 53, UNE Zone: Pursuant to 47 C.F.R. §51.507, UNE rates charged by incumbent carriers
are established according to at least three different geographic cost zones. Each CETC must report
the number of UNEs per cost zone that are used to serve lines reported on this form. Pursuant to 47
C.F.R. §51.507, the state regulatory commission with jurisdiction over the incumbent carrier’s UNE
prices prescribes the UNE cost zone names. UNE Zone names may differ from those listed on the
form. CETC may manually change UNE Zone name where required.
Loop w/o port costs:
The CETC must provide the number of UNE loops that it leases from the incumbent carrier to
provide service to end user customers within the incumbent study area. The number of loops must
be identified separately for each UNE price zone, and further itemized per residential and singleline business lines and for multi-line business lines within each UNE price zone. For CETCs that
lease UNE-platform (“UNE-P”), the CETC must report loop costs exclusive of any port costs. The
port of the UNE-P cost associated with port service must be reported separately in column 57,
“Price/port.”
Column 54, No. of Loops: CETC must report the number of UNE loops in each UNE price zone
that are leased from the incumbent carrier to provide service to customers. The number of loops

Path 2 & 3 Rural Carriers
Reporting Lines for Rural Incumbent Carriers that Elected Path 2 or 3 Disaggregation:
Pursuant to 47 C.F.R. §51.507, UNE rates charged by incumbent carriers are established according
to at least three different geographic cost zones. Each CETC must report the number of UNEs per
cost zone that are used to serve lines reported on this form. Pursuant to 47 C.F.R. §51.507, the state
regulatory commission with jurisdiction over the incumbent carrier’s UNE prices prescribes the
UNE cost zone names. UNE Zone names may differ from those listed on the form. CETC may
manually change UNE Zone name where required. CETC must be sure to list the incumbent carrier
name and SAC in items 51 and 52 for this section.
Each CETC must complete a separate worksheet for each rural incumbent carrier that has elected
Path 2 and/or Path 3 disaggregation in which the CETC is reporting access lines and for which the
CETC leases UNEs from the incumbent carrier in order to provide service to the reported access
lines. The CETC must report its lines according to the disaggregation zone names and UNE cost
zones that have been established for each incumbent carrier’s study area in which the CETC is
reporting lines. CETCs must report lines separately for each combination of UNE cost zones and
disaggregation zones in which its lines are located. For example, CETCs must separately report
lines served by UNEs leased at a unit rate of UNE Cost Zone 1 that may be located in two different
disaggregation zones of the incumbent carrier. If a CETC does not know the disaggregation path
chosen by the incumbent or the incumbent’s disaggregation zone names and boundaries, please
contact USAC’s High Cost Customer Service Center at 1-877-877-4925 for assistance.
