Workgroup Remote Access Switch 29T HE C YBERSWITCHUnique System Featuresautomatically adjust the number of network connections. Thus, your network costs will reflectthe actual bandwidth being used.• FilteringAllows you to control the flow of frames through the network. Filtering becomes necessary ifyou need to restrict remote access or control widespread transmission of sporadic messages.Customer-defined filters can forward messages based on addresses, protocol, or packet data.• Data CompressionAllows the system to negotiate compression algorithms with another device on the network.After successfully negotiating compression, data is compressed by the remote device andtransmitted to the system. The system decompresses the data, processes the informationcontained in the user data, and forwards the data as required. The system can receive datacoming over a WAN or a LAN, and compress the data before transmitting it to another deviceon the network. The net effect is to increase interconnect bandwidth by decreasingtransmission time. If negotiation for compression fails, data is transmitted uncompressed.• Dial Out CapabilityThe system will dial out to remote devices. This feature allows the system to accept user datareceived on the Ethernet LAN or ISDN network and initiate a data connection to the remotedevice specified in the user data. This allows devices on the local LAN to initiate connectionsto networks connected to the system over the switched digital network. The system monitorsthe connection for utilization and will remove the connection when it becomes idle.• Dynamic ManagementProvides a “real-time” management mechanism that allows many system parameters to bechanged without interrupting the current execution state of the system software. This featureconsists of a series of console commands that enable a user to display current systemparameters, change many parameters dynamically, and write changes to disk files so that theyremain permanent.• High Speed Digital ConnectionsThe system supports 56Kbps and 64Kbps connections to remote locations. These dial-up digitalconnections provide reliable high throughput connections for efficient data transfer for thesame cost as analog connections. If any remote devices connected to the system support multi-link PPP, up to 32 parallel connections can be made at either 56Kbps or 64Kbps.• IP FiltersThe IP filters allow you to control the transmission of individual IP packets based on the packettype. You can specify packet type by IP address (source or destination) or by IP protocol (TCP,UDP, ICMP).Once you specify a packet type, two forms of IP filtering are available:• Forwarding Filters, applied at discrete points of the IP processing path to determine if apacket continues its normal processing, and a• Connection Filter, which determines if an IP packet requiring a WAN connection may con-tinue.• Packet CaptureIn order to monitor incoming LAN data, the CyberSWITCH packet capture feature will allowyou to capture, display, save, and load bridged or routed data packets.
