Internet Service Providers (ISPs) and corporate network users have diverse sets of needs. Lucent Technologies now offers a versatile InterNetworking Systems concentrator to help meet them.
The Lucent PortMaster 3 access concentrator incorporates the ComOS® system -- one of the Internet industry's most proven InterNetworking Systems operating systems. As a result, the PortMaster 3 delivers the high reliability required for all types of applications. Our PortMaster 3 access concentrator also features advanced firewall packet filtering and comprehensive centralized management and security. So it delivers reliability ISPs and corporate network managers need. To date, over 2,000 ISPs and thousands of corporate networks trust PortMaster equipment for mission-critical connectivity. And that means you too can trust your network to PortMaster.
True DigitalTM V.90 modem technology not only helps ensure reliability, but helps "insure" it
Our True Digital V.90 modems dissipate less heat for dramatically improved reliability. Modem cards are hot-swappable to maximize up-time when adding or reconfiguring. Once installed, True Digital modems feature automatic self-configuration and real-time diagnostics. As an
added advantage, each PortMaster 3 chassis can be over-populated with modems beyond the total number of usable ports. This gives you a pool of "hot" spares as reliability insurance; that's especially valuable for remote or unstaffed POPs.In addition, the PortMaster 3 supports Stac LZS/MS-Stac data compression for ISDN or Leased Line connections, providing up to four times greater throughput. The optional Stac compression card can be easily added in the field, and supports up to 60 concurrent sessions on high-speed digital links.
Uptime that won't let you down
When it comes to LAN-to-LAN and dial-up Internet access, nothing is more critical than reliability. Our ComOS operating system delivers it. Designed specifically for connecting networks, it supplies maximum up-time. No wonder over 2,000 ISPs and thousands of corporations trust it for around-the-clock operation -- month after month, year after year.The PortMaster 3 provides multi-level security
The PortMaster 3 provides everything network managers need to easily configure and modify hierarchical security schemes for maximum dial-in security. For example, our RADIUS software supports authentication via Password Authentication Protocol (PAP), Challenge Handshake Authentication Protocol (CHAP), or callback, as well as encrypted administrative passwords.
Our built-in firewall packet filtering lets you control exactly what type of traffic can enter and exit the network. Our ChoiceNetTM filter management software provides exceptional flexibility to customize Internet access on a per-user basis. Like RADIUS software, ChoiceNet software is client/server based and centralizes the storage and management of all user filters and site lists.
