`
`Abstract
`
`
`This 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.

`
`

`
`
`

`
`
`American
`
`National
`
`Standard
`
`Approval of an American National Standard requires verification by ANSI that the
`
`
`
`
`
`
`
`
`
`
`
`
`requirements for due process, consensus, and other criteria for approval have
`
`
`
`
`
`
`
`
`
`
`
`been met by the standards developer.
`
`
`
`
`
`
`Consensus is established when, in the judgment of the ANSI Board of Standards
`
`
`
`
`
`
`
`
`
`
`
`
`
`Review, substantial agreement has been reached by directly and materially
`
`
`
`
`
`
`
`
`
`
`attected 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 effort 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

`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-Ft). 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 I performance is
`
`
`
`
`
`
`
`
`
`required for compliance with this standard; performance enhancement
`
`
`
`
`
`
`
`
`options are not required for category | 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
