Packet Optical Transport Interface

Valiant’s VCL-MX Version 6, Voice & Data Multiplexer is the time-tested work-horse of Valiant Communications which continues to be used extensively by Power Utilities, Railways, Metro Networks as well as in the Oil and Gas industry to provide all types of communication interfaces and SCADA services. The VCL-MX Version 6 Multiplexer has an expanded interface option list that provides all types of legacy Voice, Data and C37.94 Teleprotection interfaces with a frequency synchronization precision which exceeds an ITU-T G.813 compliant SSU. The Packet-Optical Network Interface option allows a smooth migration from the traditional TDM based network to a Packet-Optical based network, when required, without sacrificing the comfort or the investment in the existing legacy voice or data interfaces. The Packet-Optical Transport Network option provides a cross-connect capacity of 9Gbps and is capable of providing transmission bandwidth of almost twice the capacity of an STM-16 (SDH) link.

Features and Highlights

  • IEEE-1588v2 Synchronous Ethernet PTP Clock
  • 4 GigE Uplink Ports – Copper, Fiber, Copper + Fiber Gigabit Ethernet Ports
  • 4 x 10/100/1000BaseT Copper Ports or 4 x 1000BaseFX Optical Fiber Ports
    (User selectable combination of only 4 Copper or Fiber Ports)
  • IEEE-1588 packet synchronization mechanism provides frequency and time-of-day synchronization for all points of the network to a common, single source.
  • Industry ‘benchmark’ in transmission latency – less than 4ms for E1 Channels and 6ms for T1 Channels in IEEE-1588v2 (PTP Synchronization) versions.
  • Fully managed Layer2 Switches which offer QoS by implementing IEEE 802.1p, 802.1Q VLANs and Differentiated Services (Diffserv) and packet priority classification protocols for traffic management and optimization.
