Teleprotection over IP/MPLS, MPLS-TP

Get Data Sheet Summary Flyer

VCL-TP, Teleprotection over IP/MPLS Equipment is an extremely reliable product that offers up to 8 independent Binary Command Input and 8 independent Binary Command Output channels which can be operated selectively, or simultaneously over Ethernet / IP / MPLS-IP and MPLS-TP transmission links. The VCL-TP, Teleprotection over Ethernet/ IP/ MPLS equipment offers both, 10/100BaseT (Electric al) and 100BaseFX (Optical) Ethernet transmission interface options.

VCL-TP, Teleprotection over IP/MPLS equipment may be used in standalone point-to-point applications over Ethernet / IP/ MPLS, MPLS-TP links, or over an Ethernet over SDH (EoS) network.

Features and Highlights

  • Available in 24V DC, 48V DC, 110V DC, 220V DC, 250V DC, 110V AC and 220V AC powered configurations.

Performance:

  • Less than 2ms back-to-back transmission time and less than 3ms relay operating time. Typically, less than 5ms back-to-back command transfer time (including relay operating time).

Flexibility and User Programmability:

  • User programmable command holding delay for error resistant command inputs
  • User programmable command sampling rate for error resistant command transmission.

Network Port Specification:

Command Transmission Time < 2ms
Relay Operating Time < 3ms
Back to Back Command Transfer Time (which includes command transmission time and relay operating time) < 5ms

Maintenance:

  • Manual Loop Test: This feature initiates a “Manual Loop-Test” which verifies the integrity of the transmission link between the “Local” Teleprotection Terminal and the “Remote” Teleprotection Terminal.
  • Automatic Loop Test: The Automatic Link Test feature automatically initiates “Periodic Loop Tests” at user programmed intervals to check the integrity of the transmission link between the “Local” Teleprotection Terminal and the “Remote” Teleprotection Terminal.
  • Delay Measurement: This feature automatically initiates an end-to-end “Delay Measurement Test” between the “Local” and the “Remote” Teleprotection Terminal through the interconnecting transmission link.

Management and Monitoring:

  • RS232 serial, USB serial interfaces for local terminal access
  • 10/100BaseT Ethernet Interface for remote access over an IP network
  • Encrypted Password Protection
  • Telnet - Remote access over IP links
  • SSH - Secured remote access using Secure Shell Protocol over IP links
  • Graphical User (GUI) Interface
  • SNMP Traps and NMS for real time remote monitoring and management over an IP network
  • Automatic Link Test feature – link testing at user programmable periodical intervals
  • Visual I/O status – LED Display
  • Dry contact external alarm relay to connect an external alarm on an annunciator panel, which can be wired up for either NO or NC condition.

Event and Alarm Logging:

  • Time-Stamped Alarm Logging
  • Time-Stamped Event Logging
