ABSTRACT: This document replaces TA-NWT-001402.

GR-1402 provides the view of Telcordia on the functional requirements for performing DS3 (44.736 Mbps) High Capacity Digital Service (HCDS) access and testing. The requirements are specifically defined for Test System Controller/Remote Test Units (TSC/RTUs), Digital Test Access Units (DTAUs), Network Elements (NEs), and their related interfaces. They cover full-rate DS3 DTAU and TSC/RTU functions.

GR-1402 was partly replaced by GR-818 (functional equirements) and GR-834 (TL1 messages for DS3 HCDS access and testing).

When using GR-1402, may will need to refer to GR-818, GR-320, GR-499, ANSI 0.151, and/or IEEE 1007. You may also want to refer to GR-342, GR-811, and GR-831.
