Carrier Class NTP Server Cards for TimeHub

Plug-in NTP Server Cards Leverage the TimeHub Building Integrated Timing Supply

Symmetricom’s NTP server cards are fully integrated into the TimeHub Building Integrated Timing Supply system. NTP cards can be installed as single servers or redundant pairs in any available master or expansion shelf output slot. NTP capacity scales up at a rate of 1000 fully authenticated transactions per second for each added card. Front-access NTP traffic ports utilize Small Form-factor Pluggable (SFP) modules for flexibility to support 100/1000 Base-T electrical or 1000 base-x optical interfaces. The dual NTP traffic ports can support independent public and private network domains providing added security and flexibility. All configuration and management is consolidated through TimeHub system management ports to maintain security and isolation from NTP traffic ports.

The new NTP server cards provide superior stability and protection through direct connection to the TimeHub system backplane. NTP Stratum level 1 UTC time traceability is established with a simple connection to the TimeSource PRS Time-of-Day (ToD) output. For offices without a PRS, NTP server cards can be configured with an optional GPS, or can operate at NTP Stratum level 2 with UTC time traceability back to a NTP Stratum 1 card in another office.
