VCL-2711, IEEE C37.94 over IP/MPLS / Ethernet / MPLS-TP Transmission Equipment

Get Data Sheet

The VCL-2711, IEEE C37.94 over Ethernet / MPLS-TP / IP-MPLS Transmission Equipment is a ruggedized, robust and sub-station-hardened transmission equipment which converts and transmits up to four IEEE C37.94 Interfaces over an Ethernet / MPLS-TP / IP-MPLS link with “SDH / SONET like” performance. The VCL-2711 units must be always used in pairs, with one unit installed on each end of the Ethernet / MPLS-TP / IP-MPLS transmission link. The equipment can be used in a point-to-point, or a point-to-multipoint topology with “zero” bit-errors and almost “zero” jitter or wander when used its integrated GPS (ITU-T G.811) compliant primary reference clock.

MPLS-TP IP-MPLS Point-to-Point Point-to-Multipoint

Applications:

The VCL-2711, IEEE C37.94 over Ethernet / MPLS-TP / IP-MPLS Transmission Equipment is designed to enable sub-stations to seamlessly migrate from SDH / SONET transmission networks to more efficient IP / MPLS transmission networks without incurring large capex or requiring the tiresome task of having to replace and rewire the existing C37.94 Relays which need to be inter-connected to remote substations inter-connected over Ethernet / MPLS-TP / IP-MPLS transmission links.

VCL-2711, IEEE C37.94 over Ethernet

By installing the VCL-2711, the existing C37.94 Protection Relays can be migrated from an SDH / SONET transmission network to an
Ethernet / MPLS-TP / IP-MPLS transmission network with no degradation or compromise in the reliability or the performance of the C37.94 interfaces.
