Ethernet E1/G.703 Bridge

CT-FRM220A-Eoe1/G(S)

Image
Ethernet bridge
  • Connects one Fast Ethernet over E1 links (2.048Mbps)
  • 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).
  • Supports auto-negotiation and auto MDI/MDIX, allowing plug-and-play Ethernet connection without any additional configuration.
  • Standalone RS232 console management via CH01M
