DB-9 Adapter Description
Warning
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
intra-building port(s) of the equipment or subassembly must not be metallically connected to
interfaces that connect to the OSP or its wiring. The addition of Primary Protectors is not sufficient
protection in order to connect these interfaces metallically to OSP wiring.
