Product Overview

VCL-SafeComm-E, Ethernet Link Protection Switch provides 1+1 Network Protection between an "active" and "standby" IP networks. VCL-SafeComm-E can be used to provide link protection between IP networks across diverse domains such as fiber-radio; or fiber-satellite; or fiber-PSDN (Public Switched Data Network) to provide automatic fail-over protection to the "standby" network in the event of failure of the "primary" network.

Ethernet Link Protection Switch - Data Sheet

Features and Highlights

  • Ethernet Link Protection / Ethernet Failover Switch provides 1+1 Network Protection between an "active" and "standby" IP networks.
  • Switches and automatically re-routes IP traffic to the "standby" IP network upon the failure of the "primary" transmission network.
  • Seamless failover switching
  • Provides automatic failover protection and switching across diverse IP domains such as fiber-radio; or fiber- satellite; or fiber-PSDN (public switched data network)
  • Fail-Safe. Never becomes a point of failure. Automatically reverts to and reconnects the "primary link" even in a power down condition or system failure
  • Network failure alert. Alerts the user in the event of failure of primary or standby network
  • Touch sensitive buttons for line switching
  • Automatic keypad locking to prevent inadvertent switching
  • Syslog support
  • Maintains a history of all alarms and events including network availability
  • Maintains access log
  • Local / Remote Communication: Option to disable clear text communication to comply with NERC security requirements
  • NTP Time Synchronization
  • Remote software upgrade
  • Password strength monitoring and user access control
  • Serial Management Interface (USB) for local access
  • SNMP Management and Monitoring.

Switching Policy:

  • Automatic Failover switching – switches to standby network upon the failure of the "primary" transmission network
  • Time of day based switching
  • Day of the week / month based switching
  • Scripted message switching
  • External alarm / external trigger based switching
  • Manual switching
