Caution
The intrabuilding ports of the equipment or subassembly is only suitable
for connection to intrabuilding or unexposed wiring or cabling. The
intrabuilding ports 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 only as intrabuilding interfaces
(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.
