What are the local LAN requirements?
• LAN cabling (Ethernet) need to be high quality Category 5e or better. • LAN cable terminations should use the EIA/TIA 568A wiring scheme. • Keep cables away from electrical fields, fluorescent lighting, and electrical outlets. • Cable runs should be kept short and should NEVER exceed 100 meters (300 feet) on any Ethernet segment. If the segment needs to be over 100 meters (300 feet), we recommend that you use a fiber optic connection between the switch and the codec. Router and Switch Requirements: • Extensive testing has been done by Verizon in the lab and in the field to come up with a baseline that “works”. • Switches from the codec to the edge router should be used, NOT passive hubs. A switch reduces data traffic and collisions of packets as they are sent and received. Passive hubs should be eliminated from the path completely. • The number of switches should always be minimized between your router and codec. Each switch adds latency, which is undesirable for video conferencing.
