PortMaster 3 Feature Highlights V.90 capable. Each chassis supports six modem cards with up to ten V.90 modems per card. Analog and ISDN access with a single incoming phone number. The PortMaster 3 can intelligently switch between ISDN, ISDN data over voice, and analog modem calls over the same PRI or channelized T1 line. Ending the expense of separate chassis for each service. And enabling you to offer one phone number for all ISDN and analog calls. Scales as "Virtual chassis". Multiple PortMaster 3 servers can work together as a single virtual chassis with Multichassis Multilink PPP -- allowing even large, multi-service sites to support all dial-in traffic over a single hunt group. Multiple PortMaster 3 units can work together as a single "Virtual chassis". Unprecedented Reliability. Like all our products, the PortMaster 3 runs Lucent's ComOSTM, the industry's most dependable InterNetworking Systems operating system. Thanks to which the PortMaster 3 makes downtime virtually a thing of the past. More revenue-producing resources, without greater expense. The PortMaster 3 eliminates the waste of idle single-service ports. Because whether you're running one PortMaster 3 chassis or 100, all port resources can be pooled and available for either ISDN or analog service at any time. You get maximum utility -- and maximum revenue -- from every port. And the flexibility to meet different subscriber needs, day or night. That's what we mean by optimizing any POP. "Hot" spare modem pooling. Each chassis can be over-populated with modems beyond your total of usable ports, for a pool of "hot" spares as uptime insurance -- especially valuable for remote or unmanned POPs. Centralized management and multi-level security. The PortMaster 3 lets administrators manage InterNetworking Systems servers from a central site and easily configure, implement, and modify security schemes -- through Lucent's own RADIUS technology, now the global standard for Internet authentication and authorization, Lucent ChoiceNetTM software for tailoring Internet access on a per-user basis, and built-in firewall packet filtering.
