PortMaster 3 Integrated Access Server Product Announcement The PortMaster™ 3 is a versatile WAN access switch which integrates router, communications server, and True Digital™ modems in a single, compact, 3.5" rack-mountable chassis. It affords Internet Service Providers (ISPs) with a migration path from today's analog service to the most advanced digital (modem or ISDN) service using evolutionary third generation hardware technology and the internet proven ComOS™. Its hardware design consolidates True Digital modems, ISDN, Frame Relay and synchronous leased line service and accommodates future growth by providing distributed processing, flash 0 modem technology and a slot for optional data compression and encryption card. The PortMaster 3 offers one or two PRI (T1/E1) ports with integrated CSUs, six expansion slots for True Digital modem cards, Ethernet (BNC, AUI, 10BaseT), and an asynchronous 115.2Kbps console port. The True Digital modem cards are hot swappable and support either eight or ten 28.8 Kps (V.34) modems per card. The PortMaster 3 can support up to 48 (PRI/T1) or 60 (PRI/E1) modems via six rear panel expansion slots. Applications POP-In-A-Box The PortMaster 3 is ideally suited for POP-in-a-box applications. ISPs can use the PortMaster 3 in distributed POPs where integrating modems, ISDN, CSU, communications server and router technology is required. This ability reduces facility costs by eliminating modem racks, cables and power supplies. It further reduces the cost of deployment by providing a unified console for complete system management. Large Central Site Access The PortMaster 3 is also designed to fit in large central sites where high density is required. The PortMaster 3 is designed to support multiple calls combined across multiple chassis allowing PortMaster 3’s to be stacked in high density applications. The PortMaster 3 can also be configured with a -48V DC power supply option for Telco applications. Technology Highlights WAN Switching Due to ISDN PRI technology, a single WAN interface can be used for both analog and digital dial-in users. When a call arrives at the PortMaster 3 via PRI service, digital switching technology is employed. If the call is ISDN, the PortMaster switches the digital signal straight to the data bus for communications server processing. If the call is from a modem, the PortMaster 3 switches the modem’s digital signal directly to a True Digital modem (DSP) for processing before being transferred to the data bus. True Digital Modems True Digital modem technology means that the PortMaster 3 uses a DSP instead of an analog chip set (i.e. Rockwell or AT&T) for modem communications. By doing so, the PortMaster 3 can process a V.34 encoded signal in native digital format without needing to perform obsolete codec-based analog conversion. Processing modem calls digitally increases the performance and reliability of connections, and provides the real-time modem management capabilities required by ISPs. True Digital modems include flash memory for storing the modem code allowing an easy migration path to newer and faster modem speeds and protocols without obsoleting your investment in modem hardware. Distributed Processing Environment The PortMaster 3 implements a distributed processing environment that allows migration to new features and capabilities without sacrificing performance or requiring hardware upgrades. All HDLC and PPP processing is off-loaded from the main CPU by True Digital Modems or other WAN processors. Optional data compression and encryption functions are also off-loaded from the main CPU.
