Plug-in NTP Server Cards Leverage the SSU-2000 Synchronization Supply Unit
Carrier Class NTP:
NTP requirements in telecommunication networks have rapidly evolved from a “best effort” utility, to a mission critical requirement for high QoS content delivery. Carriers have long relied on Synchronization Supply Units (SSU’s) to meet all physical layer synchronization requirements with five nines availability. With the introduction of high performance NTP servers on a module, the SSU-2000 platform can now deliver carrier class NTP to meet demanding NGN PackeTime™ requirements.
The SSU-2000 NTP server modules provide the performance, scale, availability and security that assure high QoS delivery of advanced services such as IPTV. Today, carriers are finding that “best effort” NTP is not sufficient for high QoS packet networks and advanced services. NGN applications such as IPTV are highly dependent on carrier class NTP. Time coordination of massive amounts of digital content in the head end serving locations is reliant on accurate and secure NTP timestamps.
Symmetricom’s NTP server cards are fully integrated into the SSU-2000 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 up to 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 BaseT electrical or 1000Base-X optical or electrical interfaces. NTP server cards can support both independent public and private network domains, providing added security and flexibility. All configuration and management is consolidated through SSU-2000 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 SSU-2000 system backplane. NTP Stratum level 1 UTC time traceability is established through the GPS input module. NTP server cards can also operate at NTP Stratum level 2 with UTC time traceability back to a NTP Stratum 1 module located in another office.
