Connect WAN, LAN, and Voice Interfaces
Caution
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
connect Gigabit Ethernet ports using RJ-45 connectors for shielded twisted pair cable only to
intra-building or unexposed wiring or cable. The intra-building 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, Issue
4) 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.
