X.25 iX Network Link For HP 3000 Series 900, Technical Data Product Numbers J2070A, J2079A, 36939A, D2355A, 2340A, 2343A Introduction The X.25 iX network link is a high performance networking solution that provides connectivity to public and private X.25 packet switching networks for HP 3000/900 computers. [Figure: X.25 Network, Caption: none] Based on the modular architecture of the Datacommunications and Terminal Controller (DTC) product, X.25 iX network link offers an integrated, flexible and scalable X.25 solution for HP 3000/ 900 computers in multi-systems, multi-vendors and PAD terminal access environments. For information on other DTC products, refer to the DTC family datasheet (which presents the complete DTC family, the target environments, and supported devices) and to the individual product datasheets: DTC 16TN: HP J2060A DTC 72MX: HP J2070A DTC 16iX: HP J2062A DTC16: HP 2340A DTC48: HP 2345A DTC Management: HP D2355A HP J2120A X.25 iX Network Link: HP J2079A HP 3000 Telnet Access: HP J2080A (also included in the Networking Communications Specification Guide). Product highlights The X.25 iX network link for HP 3000/ 900 computers is a X.25 connectivity solution based on the DTC hardware and software architecture, consisting of 3 separate components: o DTC/X.25 network access card o X.25 /iX system access o DTC/X.25 management. The X.25 iX network link achieves high performance networking by offloading protocol processing from the HP 3000/ 900 host to an optimized Network Access card in the DTC. The LAN-based architecture of the DTC allows multiple HP 3000/900 hosts to share the same X.25 line, making cost-effective use of the X.25 network subscription. DTC/X.25 network access card This product is available for DTC 16 and DTC 72MX. The product is based on a high performance VLSI card residing in the DTC, used to process the X.25 protocols. The necessary software is downloaded to the DTC by the DTC management platform (HP 3000/900 or DTC management Openview Windows workstation). The DTC/X.25 Network Access card features: o X.25 protocol handling. o Support of remote PAD access function (CCITT X3, X28 and X29) allowing access to multivendor hosts (HP 3000/900 and Telnet-TCP/IP hosts) for terminals, PCs and printers attached to remote X.25 PADs. PAD access can be either direct to a single host, or user-selectable to any host on the LAN, through the DTC user interface. Connectivity of remote PAD terminals can be secured and restricted using PAD access lists, based on calling X.25 addresses and configured by the DTC /X.25 management product. Security on remote X.25 host access is implemented with Local User Group utility, which filters incoming and outgoing calls based on calling and called X.25 addresses respectively. X.25/iX System Access This software product resides on the HP 3000/900 computer. It provides interconnection of Defense Advanced Research Projects Agency (DARPA) TCP/IP protocols (layers 3 & 4 of the OSI reference model) with X.25 layer 3 of the DTC/X.25 Network Access software across the IEEE 802.3 LAN. Note that X.25 iX System Access is not an X.25 protocol implementation, but provides an X.25 addressing and facility interface between the HP 3000/900 computer and the DTC. This product allows system to system communication with remote computers, either using NS/3000iX Network services (HP 36920A), ARPA FTP service (HP 36957A), or OSI FTAM service (HP 36971A and HP 36972A). SNA connectivity for HP 3000/900 to IBM communication over X.25 is provided by the SNA/X.25 link/iX product (HP 30298A), which allows HP SNA services to be supported over an X.25 network. (Refer to the SNA/X.25 link/iX datasheet for more information). Programmatic access to X.25 level 3 is included, to allow users to develop their own protocols and services for communication with remote HP or non-HP computers over X.25 link. DTC/X.25 management This product is part of the DTC Manager application. It performs the X.25 iX network link configuration and management operations. Depending on customer network topology and requirements, the DTC/X.25 management product can be installed on two different platforms: o On a HP 3000/900: in this case, the product can only manage DTC/X.25 network links dedicated to this HP 3000/900 computer. o On an HP Openview Windows workstation. In this case, up to 60 X.25 iX network links can be simultaneously managed by a single HP Openview Windows workstation. HP Openview (PC-based) DTC Manager software provides an easy to use graphical user interface and the possibility of integrating management applications for other network elements (Switch/Pad Manager for 2335 and Model 45Plus, Openview Sysman) on the same Openview Windows workstation.
