The NetBlazer(R) LS family provides a flexible and cost-effective small office/home office (SOHO) solution for dial-up remote network access. It supports TCP/IP, Netware IPX and AppleTalk protocols and includes integrated ISDN and frame relay access.
The NetBlazer LS family of products combines all the functionality and flexibility you need to connect your smaller remote branches to one another or small office/home office sites to your regional offices and corporate networks without the need for expensive leased lines. An Integrated Services Digital Network enables telephone networks to carry data, voice and other source material. Think of the applications -- remote LAN access, telecommuting, collaborative computing and other business-to-business and small-enterprise-to-small-enterprise communications.
The LS ISDN is an ideal solution because it provides a breadth of features, including LocalTalk(R), synchronous/asynchronous ports, LAN protocol support, ISDN, frame relay and up to 4:1 compression on sync and ISDN ports. It also provides higher bandwidth than TAs attached to the NetBlazer by offloading compression processing to the LS.
The LS 2-PT provides dual sync/async ports to leverage your investment in modems, ISDN TAs or CSU/DSUs. Or, choose the LS ISDN, which also includes a single ISDN BRI port. You can connect the ISDN port to a regional or central site NetBlazer that contains a dual BRI card (NI2B).
All LS models include full router, terminal server and modem pooling capabilities and support remote control or remote node access capability. Their flexibility allows you to invest in one high-quality, yet inexpensive product to meet all your remote access needs.
With the NetBlazer LS ISDN and LS 2-PT, your small branch offices and remote sites can connect not only to the corporate LAN but to other remote office LANs as well. The LS connects over digital dial-up lines provided by the Public Switched Telephone Network (PSTN). ISDN transmits information much faster and more reliably than modems because it uses digital instead of analog lines.
You can even use ISDN for bandwidth-hungry applications such as multimedia, E-Mail, file transfer and client-server database access. To provide maximum throughput over ISDN links, the NetBlazer LS performs interface balancing -- joining ISDN's two 64Kbps B-channels for 128Kbps uncompressed throughput. In addition, because the LS supports up to 4:1 data compression on ISDN, you can achieve data transfer rates exceeding 500Kbps, or four times more than the maximum capacity of V.34 modems operating in perfect conditions. ISDN calls are often the same price as analog calls which makes the LS-ISDN an exceptionally cost-effective solution.
The NetBlazer LS can extend the LAN to traveling and work-at-home users over a dial-up link for a variety of applications. In a remote node application, the remote user's PC, Macintosh or UNIX-based workstation requires only a modem and appropriate software to become a full peer on the LAN. Remote node is beneficial in multi-protocol environments where software applications are running on your remote-client PC and you want transparent access to the corporate LAN.
For remote control, remote users can dial into the corporate LAN, select a workstation and gain LAN access by taking control of a selected workstation. The remote user gains all the capabilities of the LAN-Based workstation, including access to the network server and the workstation's hard disk. Remote control is beneficial in IPX environments where software applications do not reside on your remote workstation but need to be accessed quickly from the corporate LAN.
Finally, the NetBlazer LS provides full terminal service. As a terminal server, the LS provides terminal sessions with network hosts to users who call in, locally or remotely. The LS can provide services to dumb terminals or PCs/workstations that perform terminal emulation. The terminals can attach directly to the LS's asynchronous ports or can dial in remotely through modems.
As modem pool servers, NetBlazers such as the LS ISDN and LS 2-PT allow users access to a common pool of modems for making outbound calls. Any user on the branch-office LAN can access services on the Internet, bulletin boards and other value-added networks, such as Dialog, CompuServe, Lexis/Nexis and Prodigy without the need for a modem on every desk.
The NetBlazer LS makes remote servicing and trouble-shooting easy. With the LS, network administrators can inexpensively access the remote network. The LS provides the ability to run SNMP over dial-up links. A network administrator can use SNMP to access any device on the network and run diagnostics, view network statistics and configure workstations and routers as if connected locally. To extend the reach of your remote workstation to any IP, IPX or AppleTalk LAN in the world, simply connect the LS ISDN (with NT-1) to your ISDN jack, or use the sync/async port on your LS ISDN or LS 2-PT to connect via modem or CSU/DSU.
You can connect the NetBlazer LS to the corporate LAN over a leased line up to 128Kbps (uncompressed). The LS provides a redundant dial-up link to automatically back up and restore the leased line in the event of a leased-line failure, resulting in high reliability and cost savings. A dial-up link also can provide additional bandwidth or simultaneous access to different sites when necessary. You can interconnect the LS with any router that implements the SLIP or PPP protocol over a synchronous or asynchronous link.
Feature: You can easily configure the LS over a LAN remotely or through a direct serial link using a command line interface (over a network using telnet or through the console port); or you can also configure your LS with a setup utility.
Benefit: You can choose the configuration method that best suits your protocol familiarity and requirements.
Feature: The NetBlazer LS provides simultaneous routing of TCP/IP, Novell's IPX and AppleTalk Phase 2 protocols.
Benefit: Organizations can now easily interconnect a wide variety of remote office LANs using the NetBlazer LS.
Feature: The NetBlazer LS supports SNMP MIB II, an enterprise MIB and an SNMP MIB for all Telebit modems connected to the LS. The LS keeps a log of who dials in, when and for how long.
Benefit: Network administrators can manage the LS and modems using any SNMP-based manager such as SunNet Manager or HP OpenView. This feature enables the network administrator to manage costs and network usage.
Feature: The NetBlazer LS can operate over the following wide-area links:
Benefit: The NetBlazer LS provides comprehensive and flexible investment protection. With it, branch offices can use a variety of functions to meet growing traffic needs in an expanding business environment.
Feature: The NetBlazer LS security includes user ID/password, callback, PAP/CHAP and a DES-based cryptographic handshake. The LS also offers extensive packet filtering for IP networks on source and destination addresses. For additional security, the LS supports SecurID, a multi-protocol user authentication product from Security Dynamics and Kerberos.
Benefit: The LS provides the industry's most secure remote LAN access by allowing network administrators to control access to network resources effectively and remotely. As an on-demand gateway to the Internet, the LS provides a secure and cost-effective high-bandwidth connection.
