The XpressStack (TM) PRI platform provides high-performance access and concentration of Integrated Services Digital Network (ISDN) links. Primary Rate ISDN is the increasingly popular and affordable alternative to
expensive T1/E1 services.
XpressStack PRI in combination with Gandalf's Remote Access Concentration software (RAC) provides efficient concentration of an organization's tele-workers, remote offices, suppliers and customers, giving users instant access to data resources.
RAC features Gandalf's leading-edge data compression technology which delivers compression rates of up to 8:1. RAC supports inbound and outbound dialing, dial on demand and bandwidth on demand. RAC also supports Point-to-Point Protocol (PPP), call detail recording and a wide range of access security capabilities including PPP's Password Authentication Protocol (PAP), Challenge Handshake Authentication Protocol (CHAP) and token-based user authentication (e.g. Security Dynamics' SecurID (TM)).
Designed for performance, XpressStack PRI's sleek design employs multi-RISC processor technology to deliver the best possible throughput.
XpressStack PRI supports an ISDN PRI S/T interface providing 23 North American or 30 European 64Kbps channels. In addition, each XpressStack PRI supports one 10Base-T LAN interface and an asynchronous console port. XpressStacks can be purchased in any combination which best meets your present ISDN port-density requirements - you never have to invest more than you need.
As you purchase additional XpressStacks, your system turns into a scaleable, extendable solution by stacking and interconnecting units via XpressStack VLS (Virtual LAN Switch), a high performance Ethernet switch serving as the high-performance inter-connect mechanism for all XpressStack platforms.
XpressStack PRI's design provides investment protection with flash memory allowing XpressStack PRI platforms to be upgraded in the field with future software enhancements.
Whether stacked on a desktop or a rackmount, XpressStack PRI's diagnostic LED indicators are visible from the front panel, allowing you to easily trouble-shoot your ISDN network links. XpressStack also supports full SNMP management and Telnet access for remote configuration and management. In addition, XpressStack is available in a BRI configuration stack.
XpressStack stackable platforms, together with Gandalf's fault-tolerant Xpressway (TM) concentration systems and XpressConnect (TM) family of access products, provide you with an unsurpassed range of internetworking solutions whose matchless performance and multi-functional capabilities will protect your investment as they adapt to changing technology and future needs.
