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).
