Ethernet over E1 Converter

Ethernet Bridge over E1

The FRM220-Eoe1 is an Ethernet over E1 Bridge for cost-effective connection of 10/100Base-TX LANs over a single E1 transport. By using standard HDLC encapsulation, the FRM220-Eoe1 is able to transmit up to a 2M bits Ethernet over an E1 link. The FRM220-Eoe1 supports an E1 attenuation of up to 43 dB on twisted pair or coax cable, which provides an approximate operating range up to 2km (using 22AWG). The FRM220-Eoe1 fully meets E1 specifications including ITU-T G.703 and G.823. The FRM220-Eoe1 features diagnostic capabilities for performing remote loopback. The operator at either end of the line may test both the FRM220-Eoe1 and the line in the digital loopback mode. The Ethernet copper interface supports auto-negotiation and auto MDI/MDIX, allowing plug-and-play Ethernet connection without any additional configuration. When placed in FRM220 system, the Ethernet may be aggregated to the chassis's built in Ethernet switch. When placed in a single slot chassis and used standalone without management, the card may be configured by DIP switch.
