Description

This document compares, in an orderly manner, the transmission
requirements in ANSI/TIA-464-C-2002, "Requirements for Private
Branch eXchange (PBX) Switching Equipment" and those in ES 201 168
version 1.2.1, "Speech processing, Transmission and Quality aspects
(STQ); Transmission characteristics of digital Private Branch
eXchanges (PBXs) for interconnection to private networks, to the
public switched network or to IP gateways".

Since only the PBX transmission requirements in ANSI/TIA-464-C
and ES 201 168 are compared, it is necessary to examine relevant
portions of the scope of each of these standards to gain an overall
idea of the scope of the comparison. ES 201 168 provides
transmission requirements while ANSI/TIA-464-C provides
transmission requirements as well as other PBX parameters, e.g.,
signaling and supervision. All appearance of ANSI/TIA-464-C in this
TSB includes ANSI/TIA-464-C-1 "Telecommunications – Multiline
Terminal Systems – Requirements for PBX Switching Equipment,
