NETernity™ RM942 is a fully integrated 8-port 6U VME 100BaseFX Ethernet switch designed to support the low-cost requirements of unmanaged switch applications and converging networks. The QoS technology allows low cost unmanaged switches to carry voice, and data traffic without having to compromise the quality of its voice traffic by using the packet prioritization scheme. Packets are prioritized based upon their Layer 2 VLAN priority tag or the Layer 3 Type-Of-Service/ Differentiated Services (TOS/DS) field. This priority can be defined as transmit and/or drop priority. The RM942 has no interface to the VMEbus (only power and ground). Customers can change the factory default port setting. The RM942 has a parallel port which can connect to a PC parallel port. The tool provided runs under Windows 98 and the setting is stored on non-volatile memory. The setting can take effect immediately or on the next power up.
