`
`Abstract
`
`Thls standard presents the electrical characteristics of the Asymmetric Digital Subscriber Line
`(ADSL) signals appearing at the network interface. The physical interface between the network
`and the customer installation is also described. The transport medium for the signals is a single
`twisted-wire pair that supports both Message Telecommunications Service (POTS) and full-duplex
`(simultaneous two-way) and simplex (from the network to the customer installation) digital ser-
`vices.
`
`This interface standard provides the minimal set of requirements for satisfactory transmission
`between the network and the customer installation. Equipment may be implemented with addition-
`al functions and procedures.

`
`Amerlcan Approval of an American National Standard requires verification by ANSI that the
`N ationa|
`requirements for due process, consensus. and other criteria for approval have
`been met by the standards developer.
`Standard
`
`Consensus is established when, in the judgment of the ANSI Board of Standards
`Review, substantial agreement has been reached by directly and materially
`affected interests. Substantial agreement means much more than a simple
`majority, but not necessarily unanimity. Consensus requires that all views and
`objections be considered, and that a concerted efiort be made toward their
`resolution.
`
`The use of American National Standards is completely voluntary; their existence
`does not
`in any respect preclude anyone, whether he has approved the
`standards or not, from manufacturing, marketing, purchasing, or using products,
`processes, or procedures not conforming to the standards.
`
`The American National Standards Institute does not develop standards and will in
`no circumstances give an interpretation of any American National Standard.
`Moreover. no person shall have the right or authority to issue an interpretation of
`an American National Standard in the name oi the American National Standards
`Institute. Requests for interpretations should be addressed to the secretariat or
`sponsor whose name appears on the title page of this standard.
`
`CAUTION NOTICE: This American National Standard may be revised or
`withdrawn at any time. The procedures of the American National Standards
`Institute require that action be taken periodically to reaffirm. revise, or withdraw
`this standard. Purchasers of American National Standards may receive current
`information on all standards by calling or writing the American National Standards
`Institute.
`
`
`
`
`NOTE — The user's attention Is called to the possibility that compliance with this standard may require use of
`an invention covered by patent rights.
`
`
`By publication oi this standard, no position Is taken with respect to the validity oi this claim or of any patent
`
`
`rights in connection therewith. The patent holder has, however, filed a statement of willingness to rant a
`
`
`license under these rights on reasonable and nondiscriminatory terms and conditions to applicants esiring
`
`to obtain such a license. Details may be obtained from the publisher.

`Foreword (This foreword is not part of American National Standard T1.413-1995.)
`
`This specification of the layer 1 characteristics of the Asymmetrical Digital
`Subscriber Line (ADSL) interface to metallic loops was initiated under the
`auspices of the Accredited Standards Committee on Telecommunications,
`T1. The specification should be of interest and benefit to network providers
`and customers using multimedia services.
`
`A single twisted pair of telephone wires is used to connect two ADSL units:
`one at the central office end (an ATU-C) and one at the remote end (an
`ATU-Fi). This standard has been written to define the transport capability
`of these units on a wide variety of wire pairs and with typical impairments,
`and to help ensure proper interfacing and interworking when the two units
`are manufactured and provided independently.
`
`The ADSL simultaneously conveys all of the following: a downstream simplex
`bearer, a duplex bearer, a baseband analog duplex channel, and ADSL line
`overhead for framing, error control, operations, and maintenance. Nominal
`downstream bearer rates from 1.536 to 7 Mbit/s may be programmed. Duplex
`bearer aggregate rates from 16 to 640 kbit/s may be programmed.
`
`Two categories of performance are specified. Category l performance is
`required for compliance with this standard; performance enhancement
`options are not required for category l equipment. Category II
`is a higher
`level of performance (i.e., longer lines and greater impairments). Category
`II characteristics are not required for compliance with this standard. Three
`optional enhancements — trellis coding, transmit power boost. and echo
`cancellation — are defined for Category II equipment.
`
`A future issue of this standard may address the items listed in annex J.
`
`There are nine annexes to this standard; four are normative, and are con-
`sidered part of the standard; five are informative, and are provided for
`information only.
`
`Suggestions for improvements of this standard are welcome. They should
`be sent to the Alliance for Telecommunications Industries Solutions, 1200
`G Street. NW, Suite 500. Washington, DC 20005.
`
`This standard was processed and approved for submission to ANSI by
`Accredited Standards Committee on Telecommunications T1. Committee
`approval of the standard does not necessarily lmply that all committee
`members voted for its approval. At the time it approved this standard, com-
`mittee T1 had the following members:

`A. K. Reilly, Chairman
`G. H. Peterson, Vice-Chairman
