VCL-Ethernet over Multi E1 (4/8/16E1) 10/100Base-T / 100Base-FX to 4/8/16E1 Interface Converter
Product Brochure & Data Sheet
Product Overview
Valiant’s Ethernet over 4/8/16E1 Converter allows the user to send Ethernet data, between two points, over E1 Links. E1 Interfaces are 75 Ohms / 120 Ohms. 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.
This equipment is available in 4E1, 8E1 and 16E1 Port versions.
The equipment must be always installed and used in pairs, with one terminal being installed at either end of the E1 Link.
The VCL-Ethernet over 4/8/16E1 Converter is an Ethernet extension device, which utilizes TDM telecom infrastructure (the telecom network of E1s, or of PDH, SDH and E1/E3/SDH microwave etc.) for carrying Ethernet data. 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 at 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 at low investment.
