VCL-2709
VCL-2709, IEEE C37.94 to E1 Converter is a ruggedized, sub-station-hardened protocol converter that converts the IEEE C37.94 Interface to an E1 Interface to allow transmission of IEEE C37.94 over an E1 / SDH network
The VCL-2709 supports point-to-point applications.
Provided high-precision clock recovery and clock re-generation functions which allows error free transmission of IEEE C37.94 channels over an E1 / SDH network.
The most common application for the VCL-2709 converter is for inter-connecting IEEE C37.94 Differential Protection Relays over an E1 / SDH network between two sub-stations.
By installing a VCL-2709 converter, the existing IEEE C37.94 interfaces from protection relays can be converted to and inter-connected over an E1 / SDH network without incurring large capex, or without the tiresome task of having to replace or rewire the IEEE C37.94 Relays which need to be interconnected to the far end substations over E1 (SDH) transmission links.
VCL-2709 is available in DIN Rail mount version as well as a 1U high, standard 19-inch rack mount version.
VCL-2709 can be used over E1 / SDH network as it is described in the following application diagram:
