Ethernet over E1 Converter

Product Overview

Orion Telecom Networks Inc. offers VCL-ETH-E1 Interface Converter (Desktop Version) provides the user with Ethernet over E1 conversion enabling the user to transport Ethernet data over an E1 link.

The equipment can be installed and used in pairs, with one terminal being installed at either end of the network. This equipment can also be used with VCL-ETH-8-ML and VCL-ETH-16-ML to meet various application requirements.

The VCL-ETH-E1 Interface Converter is an Ethernet extension device utilizing TDM telecom infrastructure (the telecom network of E1s, or of PDH, SDH and E1/E3/SDH microwave etc. carrying E1s). It converts the Ethernet data into E1 frame format for transmission over the existing TDM (E1) links and then re-converts the E1 back into Ethernet data the far-end terminal, to BRIDGE two Ethernet LANs over the existing E1-based telecom network. The device can effectively utilize the redundant bandwidth of telecom operators' existing TDM network to transport Ethernet data with low investment.
