`
`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 instailation. Equipment may be implemented with addition-
`al functions and procedures.

`

`
`Arnerc-an Approval of an American National Standard requires verification by ANSI that the
`N afion a]
`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 necessarity unanimity. Consensus requires that all views and
`obiections 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
`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 of 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`withdrawn at anytime. 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 pubtication oi this standard, no position is taken with respect to the validity of this ctaim or of any patent
`rights in connection therewith. The patent holder has, however, filed a statement of willingness to grant a
`license_ under these rights on reasonable and nondiscriminatory terms and conditions to applicants desiring
