ABSTRACT: This document replaces TA-NWT-001339.

GR-1339 provides the view of Telcordia on generic hardware reliability and field reliability performance requirements that in the view of Telcordia are appropriate for most Digital Cross-Connect Systems (DCSs) network applications. A DCS terminates standard digital signals operating at DS1 and DS3 signal rates, or SONET electrical (STS-N) or optical carrier (OC-N) signal rates, and automatically cross-connects or rearranges these signals according to a network map stored in the system controller. The type of cross-connect systems described in this document include narrowband, wideband, and broadband DCSs.

It is the view of Telcordia that the requirements set forth in this document meet the needs of the customer for high availability services, customer configurable networks, and network restoration management. Future applications may place even higher demands on DCS reliability than the generic requirements set forth in this document.

When using GR-1339, you may need to refer to GR-63, GR-78, GR-474, TR-NWT-000170, TR-NWT-000233, GR-253, SR-332, GR-1244, SR-TSY-001130, and/or SR-1171, GR-284 and/or GR-929.
