Network Timing Interfaces
The RSP supports the following network timing interfaces:
• BITS input/output port—RJ48 jack
• 1 PPS input and output—Mini coax connectors
• 2.048 or 10 MHz input and output—Mini coax connectors
• Time of Day (ToD) or 1 PPS input or output port—Shielded RJ45 jack
Network timing interfaces support redundancy in a redundant RSP configuration. Network timing interfaces
on a redundant RSP remain in operation while the RSP is in hot standby mode.
