Symmetricom (News - Alert), a provider of precision time and frequency technologies, announced the latest release of SSU 2000, a Network Equipment Building System (NEBS)-certified fully manageable system that generates and distributes precise synchronization signals for both traditional SONET/SDH networks and modern Ethernet/IP networks.

The SSU 2000 release 6.2 is designed to improve network management security and dramatically increase system capacity for networks using the IEEE (News - Alert) 1588 Precision Time Protocol, company officials said.

The solution features a new communications module and software that supports RADIUS access security, which is widely deployed in remote access authentication, authorization and accounting protocol. Additionally, the SSU 2000 supports secure shell (SSH) and secure FTP (SFTP) to encrypt user authentication traffic and protect transfer of firmware upgrades.

The NEBS-compliant SSU 2000 supports the introduction and migration to Synchronous Ethernet transport technology. With SyncE, operators can introduce Ethernet elements into existing SONET/SDH networks, without overhauling the synchronization and timing of the network. SyncE, added to PTP and carrier-grade NTP, positions the SSU 2000 for all future carrier network needs.

Precision Time Protocol (PTP) capacity has more than tripled with this NEBS solution, increasing to 400 clients per module. The IEEE 1588 PTP standard is the fast-growing technology for more precise synchronization of packet-based networks. The high capacity and precise timing provided by the SSU 2000 is highly significant as mobile backhaul networks evolve to support 4G/LTE (News - Alert).

"The SSU 2000 continues to be the leading timing and synchronization platform for carriers worldwide," said Manish Gupta, vice president of marketing at Symmetricom, in a statement. "Increasing security protection and enhancing PTP capacity with this release of SSU 2000, Symmetricom continues to invest in this widely deployed platform to meet evolving customer and market demands."

The SSU 2000 release 6.2 offers a flexible, fully redundant system. With its intelligent architecture, each SSU module offers an integrated CPU running the system software.

With these capabilities, the SSU 2000 platform remains on the forefront as networks evolve from TDM (SONET and SDH) to packet-based transport using NTP, PTP and SyncE. The NEBS- certified solution meets safety and reliability standards and is also available in an ETSI (News - Alert)-standard configuration.
