Warning

To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,

connect the T1/E1 ports only to intra-building or unexposed wiring or cable. The intrabuilding cable must

be shielded and the shield must be grounded at both ends. The intra-building port(s) of the equipment or

subassembly must not be metallically connected to interfaces that connect to the OSP or its wiring. These

interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in

GR-1089-CORE) and require isolation from the exposed OSP cabling. The addition of Primary Protectors

is not sufficient protection in order to connect these interfaces metallically to OSP wiring.
