Gives criteria necessary for Network Elements (NEs) to support Layer 1 surveillance of digital transmission systems and signals. It includes both criteria that are specific to NEs that terminate or transport DS1 and/or DS3 signals, and common criteria that are applicable to multiple types of NEs and are referenced by other technology-specific documents such as (in the case of SONET) GR-253-CORE.
