ATLANTA, GEORGIA, USA (October 21, 1998) - ZNYX Corporation joined Cisco Systems at the Atlanta NetWorld+Interop in the first public demonstration of a Token Ring/Ethernet Inter-Switch Link (ISL) network adapter card.

Installed in a 400 MHz Intel® Pentium® II processor -based NT Server, the ZNYX adapter demonstrated multiple virtual LAN (VLAN) connectivity to both Token Ring and Fast Ethernet clients. Two workstations, one of them on Token Ring and another on Fast Ethernet, simultaneously accessed the same server through this single adapter, while playing a total of eight 30+ MB movie files over the network. By employing Cisco’s Token Ring over Inter-Switch Link (TRISL) technology, the adapter used the wide 100 Mbps bandwidth of Cisco’s Fast EtherChannel to simultaneously serve both the Token Ring and Fast Ethernet clients with high-speed server access.

In this configuration, the ZNYX adapter in the server was connected to a 12-port Cisco WS-X5213A Fast EtherChannel switching module in a Cisco Catalyst 5505 switch. Out of another port of the same module, a cable was connected to the Fast Ethernet client. Meanwhile, the data for the Token Ring client was passed from the WS-X5213A module through the bus of the Catalyst 5505 and was picked up by a 16-port WS-X5030 Token Ring Switching Module. A port on the WS-X5030 module then connected to the Token Ring client.

High Speed, High Reliability Alternative to High Speed Token Ring (HSTR)
Targeted at companies that have a mixture of Ethernet, Fast Ethernet and Token Ring network topologies, the ZNYX VLAN adapter technology is an ideal solution for enterprises powered with Cisco switches. Instead of operating at 16 or 4 Mbps, the ISL/TRISL technology will support network links operating at 100 Mbps or more.
