Issue Number 01
Issue Date May 1987

    ABSTRACT: This Technical Advisory (TA) provides the view of Telcordia on preliminary generic requirements for digital echo cancelers. The
    requirements specified in this document apply to echo cancelers that are built as features of a Digital Cross-connect System or other
    Digital Terminal System using a DS1 (1.544 Mbps) interface. Requirements are those characteristics that the echo canceler must have to
    satisfy the minimum needs of a typical Local Exchange Carrier (LEC).
