Document Number GR-2916
Issue Number 02
Issue Date Nov 2001
ABSTRACT: Issue 2 of GR-2916, Generic Requirements for a 5 Pin Protector Block Assembly, which replaces Issue 1, identifies proposed technical
generic requirements for protector block assemblies equipped with protector units. In the view of Telcordia, meeting these criteria
will give a telecommunications service provider a quality of service capability consistent with service objectives for telephone
service and high-speed data networks.
The information in the criteria may be useful to anyone engaged in the manufacture of protector block assemblies intended for
connection in typical telecommunications service provider facilities and/or equipment, and to those purchasing, operating, or using
such equipment. The criteria and test circuits are used to analyze equipment with respect to the following:
- Compatibility with telecommunications service provider facilities
- Potential safety hazards
- Performance and transmission characteristics
- Susceptibility to failure under environmental conditions.
The 5 pin Protection Block assembly is designed to accommodate 25, 50 or 100 pair cable. It is equipped with a multi layered printed
circuit board providing a connectorized interface for cable assemblies.
This type of Protection Block Assembly eliminates the need for wire wrapping and allows connectorization into many different
All cables connected to this unit can be removed. This allows the technicians to change out the specific cables or the entire
protection block assembly.
Issue 2 of GR-2916 updates the text, existing generic requirements, and the references section. Issue 2 also adds new generic
requirements for high speed data networks, and revises requirements to be in coordination with the requirements of plug-in protectors.
When using GR-2916, you may need to refer to GR-63.
You may also need to refer to GR-78, GR-421, GR-974, GR-1361, ANSI/NFPA 70 (the NEC), UL 497 and 746C, OSHA 174, and
