Connecting a Cable to the GNSS Antenna Interface
DETAILED STEPS
Step 1
Connect one end of a mini-coax Y-cable to the Slave unit.
Step 2
Connect one end of the split-side Y-cable mini-coax to the 10Mhz or 1PPS port on the primary RSP of the Cisco NCS
4216.
Step 3
Connect the other end of the split-side Y-cable mini-coax to the 10Mhz or 1PPS port on the backup RSP of the Cisco
NCS 4216.
Connecting Cables to the ToD Interface
SUMMARY STEPS
1. Connect one end of a straight-through Ethernet cable to the GPS unit.
2. Connect one end of the split-side Y-cable Ethernet to the ToD port on the primary RSP of the Cisco NCS
4216.
3. Connect the other end of the split-side Y-cable Ethernet to the ToD port on the backup RSP of the Cisco
NCS 4216.

To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect
Warning
the ToD 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.
For more information about GPS port pinouts, see the Troubleshooting section.
