Reference Warning, requirement, or statement
Intrabuilding or Intra-connection WARNING: The intra-building copper Ethernet ports of the equipment or
subassembly are suitable for connection to intrabuilding or unexposed
wiring or cabling only. The intra-building ports of the equipment or
subassembly MUST NOT be metallically connected to interfaces that
connect to the outside plant (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 6) 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.
