TELECOMMUNICATIONS TELEPHONE TERMINAL EQUIPMENT TRANSMISSION REQUIREMENTS FOR DIGITAL WIRELINE TELEPHONES
10-07-2013
01-12-2013
Contains voice transmission performance and compatibility requirements for digital wireline telephones including ISDN voice terminals intended for connection to a public ISDN and digital proprietary telephones connected to the ICS interface of an ISPBX as specified in the ISPBX Loss Plan section of ANS/TIA/EIA-464 B. These requirements should ensure satisfactory voice service to the user in a high percentage of installations, both initially and over some period of time, as ISDN service becomes more ubiquitous and as changes occur in telephone serving equipment. However, because of the wide range of central office switching equipment, PBX equipment, customer apparatus, and loop plant used in North America, conformity with this standard does not guarantee acceptable performance under all possible operating conditions.
