The ComNet CWFE8TX8MS Managed Ethernet Switch provides transmission of 100 BASE-TX Ethernet
data. These units are available for use with conventional CAT-5e copper transmission media. Eight
electrical ports are available for easily implementing point-to-point, linear add-drop, drop-and-repeat,
star or true self-healing ring and mesh network system architectures. The electrical ports support the
10/100 Mbps (100 BASE-TX) Ethernet IEEE 802.3 protocol, auto-negotiating and auto-MDI/MDIX features
are provided for simplicity and ease of installation. Plug-and-play design ensures ease of installation, and
no electrical adjustments are ever required. The CWFE8TX8MS incorporates LED indicators for
monitoring the operating status of the managed switch and network.

  • Page 8: Ethernet Switching Technology

    Ethernet Switching Technology Ethernet Switching Technology dramatically boosted the total bandwidth of a network, eliminated congestion problems inherent with Carrier Sense multiple access with Collision Detection (CSMA/CD) protocol, and greatly reduced unnecessary transmission. This revolutionized networking. First, by allowing two-way, simultaneous transmissions over the same port (Full-duplex), which essentially doubled the bandwidth.
