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