All kilometers and all access lines must be entered in whole numbers. All switches, tandems, hosts,
remotes, interfaces, circuit lines, carrier links, terminations, channels, copper pairs, and fiber strands
must be entered in whole numbers.
All fields must be populated. If a data field equals the quantity zero, enter the numeral zero in that
field. This is the only proper use of zero in this report. If a filing carrier has a waiver applicable to a
certain field, it must treat the data for that field as "Irretrievable" and footnote the reason for that
entry (including a cite to the waiver, and a note as to its duration). Items which need not be reported
because they do not apply are designated by N/A. DO NOT override N/As. If a reporting carrier
should wish to apply data to a field containing an N/A, the carrier should enter the amount(s) and an
explanation as a footnote to the field. The amount(s) must not be entered in an N/A’d field.
REMEMBER: Footnotes are mandatory in Table II for Rows 0410, 0460 and 0484. Footnotes are
mandatory for all “Irretrievable” entries, and for any data entry containing UNE Data.
When errata occur, carriers must include in the transmittal letter a brief statement indicating the
reason for the errata. Other explanatory notes must be included in the footnote section of the filing.
NOTICE: The ARMIS Infrastructure Report collects data designed to capture trends in telephone
industry infrastructure development under price cap regulation and improves and standardizes
existing reporting requirements for this purpose. The ARMIS Infrastructure Report specifies
information requirements in a consistent format and is essential to the FCC to monitor service
quality under price cap regulation. Your response is mandatory.
Public reporting burden for this collection of information is estimated to average 168 hours per
response, including the time for reviewing instructions, searching existing data sources, gathering

Infrastructure Report
General Instructions
For the purposes of this report, the terms access lines, lines and lines in service are used
interchangeably. Any row/column data entry which contains UNE data must be accompanied by an
explanatory footnote identifying the types of UNEs (e.g., “UNE-P”) that are included.

Table I
General Instructions
Switches - Switches are assemblies of equipment and software designed to establish connections
among lines or between lines and trunks. Switches include tandems, local, class 5 switching
machines and any associated remote switching machines; e.g., a host end office and its three
associated remote switches will be reported as four switches. However, the remote terminals of
concentrators and Integrated Digital Loop Carrier systems are not reported in this table, because they
are not switching entities. There may be more than one switch per central office or wire center.
Lines in Service - Access lines include all classifications of local exchange telephone service
including, but not limited to, individual lines, party line access, PBX access, Centrex access, Coin
access, Foreign Exchange access and WATS access. Access lines, as defined herein, is a more
inclusive term than billable access lines, as defined in the ARMIS 43-01 Report. See row
instructions for Rows 2090 through 2140 of the ARMIS 43-01 Report for the definition of billable
access lines. Report all access lines in whole numbers.
Row Instructions
Row 0110 - Total Switches - Enter in whole numbers, the total quantity of local and tandem
switches. This amount is equal to the sum of Rows 0150 and 0170. Local switches include both
host switches and their associated remote switches. Remote switches to be included in the total
switches count are those described in the general definition of a remote switch.1 A remote switch
can generally be described as a switch that has no connection to the facilities network except through
its host switch. The host provides the processing capabilities and certain control functions for the
remote switch under the direction of the host central processor, and controls the remote switch over a
pair of dedicated data links.
Note: Since some switches are used for both local and tandem switching, the sum of Rows 0111 and
1

See Adjustments to Price Cap Carriers’ Service Quality and Infrastructure Reports in ARMIS, CC Docket No.
87-313, Public Notice, 7 FCC Rcd 3591 (Com. Car. Bur. 1992). Technically concise definitions of “host” and
“remote” switches are found in the Local Exchange Routing Guide.

0112 may be greater than the amount entered on this row. For example, if there are 6 local switches,
4 tandem switches and 5 switches that are used for both local and tandem switching, Row 0111
would equal 11 local switches, Row 0112 would equal 9 switches, and Row 0110 would equal 15
switches. In this case, the sum of Rows 0111 and 0112 (20) would be greater than the amount of
total switches (15).
Also, since we are asking only for the number of remote switches with stand-alone capability in
Row 0114, this quantity will be less than the number of remote switches included in Row 0110. This
is because Row 110 includes the total of both stand-alone and non stand-alone remote switches. For
example, if there are 16 total remote switches, where 7 have stand-alone capability and 9 do not, the
quantity entered on Row 0114 (7) would be less than the number of remote switches included in
Row 0110 (16).
Row 0111 - Local Switches - Enter in whole numbers, the total quantity of switches used as local
switches. Local switches encompass switches with no subtending remote switches, as well as host
switches and their associated remote switches (both stand-alone and non stand-alone).
Row 0112 - Tandems - Enter in whole numbers, the total quantity of switches that perform tandem
switching.
Row 0113 – Host Switches - Enter in whole numbers, the total quantity of host switches. A host
switch is a switch that serves one or more remote switches.
Row 0114 – Remote Switches (Stand-Alone Only) - Enter in whole numbers, the total quantity of
remote stand-alone switches. Include on this row, only those remote switches that are equipped to
operate in a stand-alone fashion (i.e., able to operate if the host fails, or if the data links to the host
fail) to be able to provide more limited service. Remote switches that are not within this description,
i.e., those that are non stand-alone remote switches, should not be included on this row.
Note: A remote switch can generally be described as a switch that has no connection to the facilities
network except through its host switch. The host provides the processing capabilities and certain
control functions for the remote switch under the direction of the host central processor, and controls
the remote switch over a pair of dedicated data links. All types of remote switches, i.e., both standalone and non stand-alone, are included with the switch counts in Row 0110 and Row 0111.
However, Row 0114 excludes remote switches that are incapable of providing stand-alone operation
when the host switch fails.
Row 0120 - Total Number Access Lines In Service - Enter in whole numbers, the total quantity of
access lines in service. This amount is equal to the sum of Rows 0160 and 0180.
Type of Switch - Types of switches include Non-Digital Stored Program Controlled (NDSPC) and
Digital Stored Program Controlled (DSPC).

Row 0150 - Total NDSPC Switches - Enter in whole numbers, the total quantity of local and tandem
Non-Digital Stored Program Controlled switches.
Row 0160 - NDSPC Lines Served - Enter in whole numbers, the total quantity of lines served by
Non-Digital Stored Program Controlled switches.
Row 0170 - Total DSPC Switches - Enter in whole numbers, the total quantity of local and tandem
Digital Stored Program Controlled switches.
Row 0180 - DSPC Lines Served - Enter in whole numbers, the total quantity of lines served by

Row 0230 - Total Switches Equipped with SS7 - Enter in whole numbers, the total quantity of local
and tandem switches equipped with SS7.
Row 0240 - Local Switches Equipped with SS7 - Enter in whole numbers, the total quantity of
switches used as local switches that are equipped with SS7.
Row 0250 - Tandems Equipped with SS7 - Enter in whole numbers, the total quantity of switches
that perform tandem switching and are equipped with SS7.
Row 0270 - Total Switches Equipped with ISDN - Enter in whole numbers, the total quantity of
local and tandem switches that are equipped with ISDN. Since some switches are used for both
local and tandem switching, the sum of Rows 0280 and 0290 may be greater than the amounts
entered on this row (see example, Row 0110).
Row 0280 - Local Switches Equipped with ISDN - Enter in whole numbers, the total quantity of
local switches that are equipped with ISDN.
Row 0290 - Tandems Equipped with ISDN - Enter in whole numbers, the total quantity of switches
with tandem capability that are equipped with ISDN.
Row 0300 - Lines Served by ISDN Switches - Enter in whole numbers, the total quantity of lines
served by switches equipped with ISDN. Do not include in this count lines that could be connected
to switches equipped with ISDN.
Row 0311 - Basic Rate ISDN (BRI) Interfaces Equipped - Basic rate ISDN consists of two Bearer
Channels at 64 Kilobits/second and one Delta Channel at 16 kilobits/second. Quantities reflected
are the number of (2B + D) BRI interfaces equipped. This amount represents actual interfaces
equipped with ISDN. Enter in whole numbers.
Row 0312 - Primary Rate ISDN (PRI) Interfaces Equipped - Equivalent primary rate ISDN
interfaces are generally configured as 23 Bearer Channels and one Delta Channel all at 64
kilobits/second. Quantities reflected are the number of equivalent PRI (23B + D) ISDN interfaces

equipped, excluding interoffice PRI ISDN interfaces. This amount represents actual interfaces
equipped with ISDN. Enter in whole numbers.

Table II
Row 0320 - Total Sheath Kilometers - The total length in kilometers of all loop and interoffice
cables (Plant in Service – Account 2410) without regard to the number of pairs. Use whole
numbers. Row 0320 shall equal the sum of Rows 0321, 0322, and 0323.
Row 0321 - Copper - Enter the number of sheath kilometers of twisted pair copper cable. Use whole
numbers.
Row 0322 - Fiber - Enter the number of sheath kilometers of fiber. Use whole numbers.
Row 0323 - Other - Enter the number of sheath kilometers of aluminum, coaxial, and all other sheath
kilometers not included in Rows 0321 or 0322. Use whole numbers.
Row 0330 - Total Circuit Links - A circuit link is that link that exists between points A and B where
voice frequency/DS0 cross-connects and/or analog/digital conversion (collectively referenced here
as conversion) occurs. Circuit links are counted as follows: If there is a circuit between A and B
with no intermediate conversions, count one circuit link for each voice frequency equivalent
channel. If there is a circuit between A and B with one intermediate conversion, count two circuit
links for each voice frequency equivalent channel. Similarly, two intermediate conversions between
A and B would result in three circuit links per voice equivalent channel. Enter in whole numbers.
LOOP PLANT - CENTRAL OFFICE TERMINATIONS – The quantities reported in Rows 0370
through 0460, expressed as 4 kHz channels, refer to facilities that connect end user customers with
their serving wire centers / central offices. This measure also includes the “local channel” portions
of Special Access / private line / special services connecting end user customers with their serving
wire centers or central offices. However, “Local Loop Plant” excludes facilities connecting serving
wire centers / central offices to interexchange carrier (IXC) or other access customer points of
presence (POP) because these channels are considered interoffice circuits. For Row 0390, working
fiber digital carrier, and Row 0440, equipped fiber digital carrier, do not include channel counts for
optical carrier that is terminated at end user/customer premises. Instead, count channels from these
systems, as instructed, in Row 0484, Fiber Terminated at Customer Premises at DS3 Rate or Higher.
Row 0370 - Total Working Channels - Working Channels are on a 4 kHz bandwidth (single voice
channel) basis. Working channels originating from a remote switch are treated the same as if the
channels originated in the host central office. This amount equals the sum of Rows 0380, 0390 and
0410. Enter in whole numbers.

FCC Report 43-07 - Rep. Def. – Column Descriptions

Fiber Terminated at the Customer Premises at DS3 Rate or Higher.
Row 0410 - Other - Enter the number of other working channels. Use whole numbers. Explain the
data entered here in a footnote.
Row 0420 - Total Equipped Channels - Equipped channels are on a 4 kHz bandwidth (single voice
channel) basis. Equipped channels originating from a remote switch are treated the same as if the
channels originated in the host central office. This amount equals the sum of Rows 0430, 0440 and
0460. Use whole numbers.
Row 0430 - Copper - Enter the number of equipped channels on copper facilities and systems. Use
whole numbers. This amount equals the sum of Rows 0431, 0432 and 0433.
Row 0431 - Baseband - Enter the number of equipped channels on copper baseband facilities. Use
