10. Interface This is not to say that conventional communications cannot share the same network hardware with a BASIS 914lz In fact common network hardware such as managed Ethernet switches and media converters can service both BASIS 914lz products and conventional data communications equipment so long as the man aged switch or media converter are partitioned into separate network domains This is normally done by configuring a separate VLAN for each data type Some switches may allow individual port assignments or support partitions through DIP switch selection Second CobraNet audio must traverse either a repeater domain or a network switch domain The point here is that the CobraNet port on a BASIS 914lz must connect directly to and only to either a repeater LAN or a switched Ethernet LAN Hybrid networks containing both repeaters and switches are not permitted on the audio segment Connecting the CobraNet port to a repeater that is in turn con nected to a network switch poses an illegal and non compliant condition We recommend always connecting the OSControl and or CobraNet port s directly to network switch ports Third the BASIS 914lz and OSControl net system are targeted at network switch deployments The consumer costs of Ethernet switches have continued to fall over the last several years and are now comparable with repeaters on a per port basis In addition the sophistication and scalability of network switches make them ideal for new ins
