7 Vendor Documentation

The term “documentation” as used in this section refers to vendor documentation as defined in GR-2914-CORE and GR-454-CORE.

Vendor documentation is an integral part of the network equipment and shall be validated/tested by the vendor before delivery to AT&T to insure its accuracy, comprehensibility, comprehensiveness and completeness as defined and measured by the following documents and guidelines. Critical or Major Documentation deficiencies (determined by AT&T) can delay equipment deployment until corrected by the vendor and approved by AT&T. The requirements contained in this section are supplemental to other documents that govern vendor documentation such as GR-454-CORE and GR-2914-CORE.
