VCL-2709, IEEE C37.94 to E1 Converter

Get Data Sheet

The VCL-2709, IEEE C37.94 to E1 Converter is a ruggedized and robust, sub-station-hardened protocol converter that converts IEEE C37.94 data to E1 data. VCL-2709 supports point-to-point applications. VCL-2709, IEEE C37.94 to E1 equipment includes precise clock recovery and clock re-generation functions which allows the transmission of IEEE C37.94 channels over an E1/SDH network for error free transmission. The most common application for the VCL-2709 converter is for augmenting legacy IEEE C37.94 data transmission over an E1 network between two sub-stations.
