Note
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
Warning
connect the BITS ports only to intra-building or unexposed wiring or cable. The intrabuilding 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) 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.

Use of two BITS sources or a Y-cable is optional. Each BITS input port is routed to both RSPs,
so that SETS device on each RSP has visibility to both BITS inputs.
