The NetBlazer PN family of products combines all the functionality you need to connect your smaller remote branches or sites to your regional offices and corporate networks without the need for expensive leased lines. The PN products complement Telebit's long-established range of dial-up routing solutions, but on a scale suitable for smaller remote offices.
The PN is an ideal solution because it integrates several functions -- router, hub and dial-up -- into one product.
You can choose either ethernet or 10Base-T Hub versions in these three configurations:
All PN models include full router, terminal server and modem pooling capabilities, and support remote control or remote node access capability. The flexibility of the PN family of products allows you to invest only in what you need, and nothing more.
With the NetBlazer PN, your small branch offices and remote sites can connect not only to the corporate LAN but to other remote office LANs as well. The PN connects over analog dial-up lines provided by the Public Switched Telephone Network (PSTN).
You can use dial-up links for applications such as E-Mail, file transfer and client-server database access. The PN provides on-demand, transparent connectivity to other LANs, automatically configuring and dialing modems that are attached to it.
To provide maximum throughput over these dial-up links, the NetBlazer PN can also inverse multiplex, or aggregate bandwidth over multiple modems, to increase throughput.
You can also use the NetBlazer PN to connect remote office LANs to one another or to the corporate network over a Switched 56/64Kbps or basic-rate ISDN interface using an external terminal adapter (TA). The PN automatically dials using V.25bis commands or Hayes AT commands.
You can connect the NetBlazer PN to the corporate LAN over a leased line up to 128Kbps using an external CSU/DSU. The PN provides a redundant dial-up link to automatically backup and restore the leased line in the event of a leased-line failure. This results 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 PN with any router that implements the PPP or SLIP protocol over a synchronous link.
The NetBlazer PN can extend the LAN to traveling and at-home users over a dial-up link in 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 and where software applications do not reside on your remote workstation but need to be accessed quickly from the corporate LAN.
Finally, the NetBlazer PN provides full terminal service. As a terminal server, the PN provides terminal sessions with network hosts to users who call in locally or remotely. The PN can provide services to dumb terminals or PCs/workstations that perform terminal emulation. The terminals can attach directly to the PN's asynchronous ports, or can dial in remotely through modems. Because the NetBlazer PN also supports Binary Telnet, it supports X-Windows terminals and file transfers.
As modem pool servers, NetBlazers such as the PN4 allow users access to a common pool of modems for making outbound calls. Any user on the branch-office LAN can access the Internet, bulletin boards and other value-added networks, such as CompuServe, Dialog and Lexis/Nexis without the need for a modem on every desk.
The NetBlazer PN makes remote servicing and troubleshooting easy. With the PN, network administrators can inexpensively access the remote network. The PN 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. Simply connect the NetBlazer PN to a standard telephone jack to extend the reach of a remote workstation to any IP, IPX or AppleTalk LAN in the world.
Feature: The NetBlazer PN provides simultaneous routing of TCP/IP, Novell's IPX and AppleTalk Phase 2 protocols. A variety of users can transparently connect to the corporate LAN.
Benefit: Organizations can now easily interconnect a wide variety of remote office LANs using the NetBlazer PN.
Benefit: The NetBlazer PN provides flexibility and investment protection. A branch office could start with modems and upgrade to ISDN, leased lines or switched 56Kbps for growing traffic needs.
Feature: Three PN models include eight 10Base-T connections. This hub option allows you to connect up to eight PCs, Macintoshes, UNIX workstations and notebook computers over a 10Base-T ethernet network using unshielded twisted-pair wire. You can also connect, or cascade, up to eight additional hubs to the PN hub to expand your ethernet LAN.
Benefit: The PN provides complete branch office connectivity in one product. Integrating hub and routing functionality makes an ideal low-cost LAN/WAN solution for small remote sites.
Feature: The NetBlazer PN security includes user ID/password, callback and a DES-based cryptographic handshake. The PN also offers extensive packet filtering for IP networks on source and destination addresses. For additional security, the PN supports SecurID, a multi-protocol user authentication product from Security Dynamics and Kerberos, an MIT-developed IP authentication scheme.
