Teleprotection over IP/MPLS, MPLS-TP

Product Overview

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.
