Or call us on

The FRM220A-iMux is an E1 inverse multiplexer capable of bundling 4E1/ 8E1/16E1 lines for cost-effective connection of10/100Base-TX LANs over multiple E1 transports. The FRM220A- iMux transmits 7.93Mbps (iMUX4)/ 15.87Mbps(iMUX8)/31.74Mbps(iMUX16) Ethernet bridge channel (GFP-F encapsulated) over multiple E1 links. The FRM220A-iMux bridges thegap between E1 and E3, allowing bridges to operate at faster rates. It also provides high speed access to SDH/SONETbackbones where the only access services available are E1 lines. The FRM220A-iMux supports E1 attenuation of up to 43dB on twisted pair or coax cable. This provides an approximate operating range up to 2km (using 22AWG). The FRM220AiMUXfully comply the E1 specifications including ITU-T G.703 and G.823. The FRM220A-iMux features diagnosticcapabilities for performing remote loopback The operator at either end of the line may test both FRM220A-iMux NTU andthe 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.
