AppendixIII-Bibliography Abstract
Defines a transmission technique known as High bit rate Digital Subscriber Line (HDSL), as a means for the transportation of several types of applications. This document specifies the requirements for the individual HDSL transmission type system, the transmission performance, the HDSL maintenance requirements and procedures.
