Ethernet over 16 E1 Converter

Ethernet over 16E1 - Front Valiant’s Ethernet over 16E1 Converter allows the user to send Ethernet data, between Ethernet over 16E1 - Back two points, over E1 links. E1 Interfaces are 120 Ohms (75 Ohms is optional). Ethernet Interface options may be ordered as 10/100 Base-T Electrical Ethernet or 100Base-FX Optical Ethernet over 850nm/1310nm/1550nm single mode optical fiber interfaces.

The equipment be always installed and used in pairs, with one terminal being installed at either end of the E1 link.

The VCL-Ethernet over 16E1 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 existing TDM network to transport Ethernet data with low investment.

Ethernet over 1 / 4 / 8 E1s are also available and offered.

Applications:

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.
