Multiple Chassis Connectors
SYNC IN and SYNC OUT Connectors
These RJ-45 connectors are used to interconnect multiple Spirent chassis/appliances. The
SYNC OUT on the Sync Master is connected to the SYNC IN on the Sync Slave. For
longer multiple chassis chains, the SYNC OUT on the Sync Slave is connected to the
SYNC IN of the next Sync Slave. This connection arrangement can theoretically
accommodate up to 255 chassis.
External Time Reference (ETR) Connectors
The Spirent chassis contains these connectors that are currently supported for use with
External Time Reference (ETR) equipment connections: the External Time Reference
Serial DCE connector RJ-45); the External Time Reference 10 MHz connector (SMA);
and the External Time Reference 1 PPS connector (SMA).
