Product Overview
The VCL-2145-SSU, is specifically designed to provide reliable and high precision synchronization in 2G, 3G, HetNet and LTE mobile telecommunications networks as well as backhaul wire-line SDH / SONET and Synchronous Ethernet networks. 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.
Fully Reliable / Redundant Equipment, High Performance Network

The VCL-2145-SSU accepts a wide range of input and outputs. Output capabilities allow it to support legacy frequency timing applications, including E1/ T1, 10 MHz, 1 PPS (PPS) as well as Time-Of-Day (ToD) using redundant Input / Output Clock cards. Additionally, the SSU may also be used to provide IEEE-1588v2 PTP Grandmaster and NTP Outputs. Optional interfaces include IEEE-1588v2 PTP Grandmaster and NTP Outputs.
VCL-2145-SSU provides protection that is superior to “network redundancy” which must re-acquire synchronization from a different Clock Equipment located elsewhere in the network.
. PTP Grandmaster is Modular and compact 6U, 19” or ETSI rack mountable equipment to provide network synchronization
. Fully integrated – IEEE 1588 (2008) v2 PTP server and NTP Server
. High capacity (up to 16,384 PTP slaves / clients) per chassis.
. Compliant with ITU-T Telecom Profile G8265.1 and G8275.1
. High PTP message rate (up to 128 messages per second)
. Single or dual GNSS (GPS) inputs with Stratum 1
. Single platform for traditional TDM, PTP, NTP and SyncE
. Integrated with Next Generation Networks synchronization
. Time-of Day Server
. Timing sources for Sync-E, Ethernet Network Equipment
. OCXO and Rubidium (RbXO) Holdover clock options
. Protection / Redundancy: Module protection for all critical functions (Inputs, Holdover Clock, Outputs, Power)
. Fully manageable Local and Remote Graphical User Interface (Omni View)
- VCL-2145-SSU hardware design is intended to integrate intelligent, functional modules into a flexible, fully protected / fully redundant system to seamlessly satisfy current and future customer requirements to provide Phase, frequency time synchronization over packet based networks.
- VCL-2145-SSU integrated up to 6 high performance modules enabling a total capacity of more than 6,000 PTP slave clients. Each module integrated with PTP Engine with accurate time stamping and supports 1024 PTP Clients each card.
- Automatic Redundant configuration: If a primary card/module is installed in a slot, the new secondary card/module will be automatically configured to the same settings, as the primary card/module.
- Input signals from GNSS (GPS/GLONASS) are by-passed / switched / passed-through in case of any function / card level failure.
