Overview
The BYC-C4 is an inverse E1 multiplexer that will multi-link up to 4 E1 lines and offers simple, cost-effective connection between E1 service and 10/100Base-T LANs. The BYC-C4 inverse multiplexer transmits a 7.68Mbps Ethernet bridge channel over 4 E1 links. The BYC-C4 supports 4*2.048Kbps G.703 E1 lines, for a line attenuation of up to 43 dB on twisted pair or coax cable.
The BYC-C4 fully meets El specifications including ITU-T G.703 and G.823. The Ethernet interface supports auto-negotiation, allowing plug-and-play Ethernet connection without any additional configuration
