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.
The DB-9 adapter allows you to connect the timing signals (building integrated timing supply (BITS),
