The VCL-2145-SSU is specifically designed to provide reliable and high precision synchronization in
2G, 3G, 5G, HetNet and LTE mobile telecommunications networks as well as backhaul wire-line SDH / SONET and Synchronous Ethernet networks.
The VCL-2145-SSU System is compliant with ITU-T G.811 standards. It may be also used by Railways, Airports (and Air-Traffic Control),
Power Generation and Distribution companies and other Utility companies who require fail-safe, high-reliability and precise synchronized
synchronization outputs that are concurrently locked to GNSS (GPS/GLONASS) References. In addition to traditional TDM network timing
capabilities, the VCL-2145-SSU supports packet networks with signals including IEEE 1588 Precision Time Protocol (PTP) and Network Time
Protocol (NTP) for advanced network services.
The SSU accepts single or dual GPS primary receiver modules to meet primary reference clock requirements, which provides the following key benefits:
The VCL-2145-SSU's accepts up to eight output modules, providing 192 outputs. The output modules may also be configured for redundant operation that supplies 24 protected outputs per pair. Various output modules are available to meet specific signal and interconnection requirements including E1, T1, RS-422, NTP, IRIG-B and IEEE 1588 PTP. The activation of the output's ports are fully user controllable.
In case of loss of GPS and input references, the VCL-2145-SSU uses intelligent software to provide enhanced output performance beyond the required holdover stability. Its superior holdover capability retains stratum G.812 performance for three weeks during holdover conditions with a rubidium clock.
