Ethernet over 8 E1 Converter

Product Overview

Orion’s Ethernet over 8E1 Converter allows the user to send Ethernet data, between two points, over E1 links. E1 Interfaces are 120 Ohms. Ethernet Interface options may be ordered as 10/100Base-T Electrical Ethernet or 100Base-FX Optical Ethernet over 850nm/1310nm/ 1550nm single mode optical fiber interfaces.

Applications

The equipment may be used for the following purposes:

• Bridging Ethernet LANs over existing TDM (E1) telecom network.
• Extending Ethernet networks utilizing TDM (E1) landline based telecom infrastructure.
• Interconnecting DSLAMs to Central Routers over PDH/SDH
• Interconnecting IP based GSM base stations
• Interconnecting WiMAX base stations
• Using telecom network of E1s / PDH / SDH microwave etc. carrying E1s to transport Ethernet data.

In all cases the equipment be always installed and used in pairs, with one terminal being installed at either end of  the network.
