This T1 technical report discusses the transmission performance of unbundled voicegrade analog loops and is intended to help the telecommunications industry plan quality voicegrade local networks. The report provides performance information for unbundled subscriber access wherein the unbundled subscriber loop is connected to a competitive/incumbent local exchange carrier (CLEC/ILEC) inter-network interface (INI). This connection takes place when the CLEC is collocated and the ILEC distribution frame (DF) terminates the loop. Furthermore, the technical report reviews local access lines by discussing ANSI IEEE 820-1992, loop design methodologies, signal levels, and bridged taps. Finally, the document considers treated lines by reviewing ANSI T1.512- 1994(R1999) and historical information regarding switched treated lines. This document is written in the context of a carrier purchasing connectivity to the end-user, i.e., subscriber access. The document focuses only on analog voiceband services.
