___________________________________________________________________ PRODUCT NAME: WAN Support for DIGITAL UNIX Systems V3.0 SPD 42.47.12 DESCRIPTION Wide Area Networking (WAN) Support for DIGITAL UNIX[R] Systems is a layered software product for Alpha systems running DIGITAL UNIX. It enables appropriately configured systems to connect to an X.25 Packet Switched Data Network (PSDN) by an X.25 Relay node on the same local area network (LAN) or directly by a synchronous communications link. The product provides further software enabling systems to connect di- rectly to a supported Integrated Services Digital Network (ISDN) for Basic Rate Access [1] , as well as support for access to mobile packet- radio networks. The product supports communications by PSDNs conforming to ITU/TSS rec- ommendation X.25 1980, 1984, and 1988 or to international standard ISO 8208. Refer to the SUPPORTED PUBLIC NETWORKS section for the list of supported PSDNs. WAN Support for DIGITAL UNIX Systems also provides the device drivers and specific datalink protocol support for Digital Equipment Corpo- ration's synchronous communications options for DIGITAL UNIX systems. Applications programming interfaces to the serial synchronous device drivers (HDLC framing operation) and to the datalink (LAPB, HDLC, LLC2), are included. WAN Support for DIGITAL UNIX allows a DIGITAL UNIX system to: o Act as a packet-mode DTE connected to a supported PSDN o Support ISO 8208 DTE to DTE point-to-point operation o Act as a packet-mode DTE connected to a LAN o Act as an X.25 Relay node conforming to ISO Technical Report 10029 ____________________ [1] Support available only for DEC 3000 model machines supplied with the integral BRA ISDN device. See Table 7. May 1997 AE-PR2VH-TE WAN Support for DIGITAL UNIX Systems V3.0 SPD 42.47.12 o Act as a wireless server for mobile packet-radio network clients o Provide an X.25 subnetwork for DECnet/OSI CONS and CLNS operation o Provide a DEC-HDLC point-to-point datalink for DECnet/OSI CLNS op- eration o Act as a functional TE connected at reference point "S" to a sup- ported ISDN o Connect to a supported PSDN Access Unit by a circuit switched ISDN B-Channel; and o Act as a combination of the above The following limitations of WAN Support for DIGITAL UNIX should be noted: o The multihost mode of operation available in the VAX P.S.I. prod- uct is not provided. o DCE mode is not supported. o Use of the D-bit in data packets is not supported. o DEC-HDLC point-to-point datalinks for DECnet/OSI CLNS operation are not supported over ISDN connections. o Operation of the Internet protocol facilities (TCP/IP) over DEC- HDLC, available in the WANDD for ULTRIX product, is not supported. o There is no programming interface provided for direct access to the ISDN call control component or raw B-channel data transfer. WAN Support for DIGITAL UNIX supports the following functions: o X.25 Relay WAN Support for DIGITAL UNIX allows an appropriately configured Al- pha system to relay X.25 packets between a LAN and a synchronous com- munications link to a PSDN. o DECnet/OSI Connectionless Network Service 2 WAN Support for DIGITAL UNIX Systems V3.0 SPD 42.47.12 The product supports the use of the DEC-HDLC and X.25 protocols as sub- networks for the OSI Connectionless-Mode Network Service (CLNS). o DECnet/OSI Connection Oriented Network Service The product supports the OSI Connection Oriented Network Service (CONS) for communications over X.25 subnetworks. o TCP/IP over X.25 An X.25 SVC can be used as the datalink protocol for IP traffic in ac- cordance with RFC-1356 (which supersedes and is compatible with RFC- 877). o TCP/IP over ISDN An ISDN circuit switched B-channel can be used to transport IP traf- fic using the Point-to-Point Protocol (PPP) in accordance with Inter- net RFC-1331. o X.25 and higher layers over Circuit Switched ISDN The product supports ISDN circuit switched B-channel access to a PSDN Access Unit (AU). This allows X.25 traffic over an ISDN connection in accordance with reference configuration "Configuration when access- ing PSPDN services (case A)" of ITU/TSS standard X.31. All function- ality listed as supported for X.25 switched virtual circuits is then available over the ISDN link. This functionality also allows two end nodes to communicate using X.25 in a DTE-to-DTE configuration over an ISDN circuit switched B-channel. o Process-to-Process (X.25) Communications WAN Support for DIGITAL UNIX provides C callable library functions that allow user programs access to the X.25 network services, the LAPB/E datalink, and to the device drivers themselves (HDLC framing only). o Process-to-Terminal (X.29) Communications Through the programming interface, users of the DIGITAL UNIX system may make outgoing calls to other DIGITAL or non-DIGITAL systems or suit- able network PADs accessible by a PSDN. o Terminal-to-Process (X.29) Communications 3 WAN Support for DIGITAL UNIX Systems V3.0 SPD 42.47.12 Remote terminals connected to the PSDN may access the DIGITAL UNIX host running X.25 by means of an X.29 Switched Virtual Circuit (SVC) call. o Wireless Communications Wireless clients operating on mobile packet-radio networks using the supported mobile switches (see Table 6) can access a DIGITAL UNIX server by means of X.25. o X.25 Mail The X.25 Mail utility allows communications across a PSDN by electronic mail between two systems running the Mail-11 protocol over X.25. This mail facility does not require DECnet to be installed on the system. Systems that support Mail-11 over X.25 include WAN Support for DIG- ITAL UNIX and VAX P.S.I. Features Conformance to Standards WAN Support for DIGITAL UNIX complies with the following standards: o ITU/TSS recommendations-Q.921, Q.931, X.31 (1988), X.25 (1980, 1984, or 1988), X.3, X28, X.29 o International standards-ISO 8208, 7776, 8881, 8802/2, 8878, 8473, TR10029 o Internet RFCs-1356 (which supersedes and is compatible with 877), 1331, 1332 Virtual Circuits WAN Support for DIGITAL UNIX offers communication over both Permanent Virtual Circuits (PVCs) and Switched Virtual Circuits (SVCs), and sup- ports up to 4,096 virtual circuits in total per system. One virtual circuit is used for each incoming or outgoing X.29 terminal connec- tion, for each X.25 call, and for each DECnet/OSI routing circuit and transport connection. The use of PVCs for X.29 communications is not 4 WAN Support for DIGITAL UNIX Systems V3.0 SPD 42.47.12 defined by the 1980 and 1984 ITU/TSS recommendations, and is not avail- able with WAN Support for DIGITAL UNIX. PVCs are not supported when accessing a PSDN by an ISDN call or when using IP over X.25. Process-to-Process Communications The WAN Support for DIGITAL UNIX programming interface allows appli- cation programs to access X.25 packet level services by C callable li- brary routines. Functions include the establishment and clearing of network connections, the transmission and reception of data, the send- ing and receiving of interrupt messages, and the resetting of virtual circuits. The interface also provides for the segmentation and recom- bination of messages that are longer than the packet size selected for the circuit. This interface enables an application program using the X.25 library to communicate with complementary X.25 software on other systems (DIG- ITAL or non-DIGITAL). The product also provides physical layer and datalink synchronous com- munications services to user-level processes that require direct ac- cess to the device drivers and datalink protocol. Note that only HDLC- framing operation is supported. Terminal Communications WAN Support for DIGITAL UNIX supports terminal communications accord- ing to ITU/TSS recommendations X.3, X.28, and X.29. Only those ter- minal parameters defined in the X.3 recommendation are explicitly sup- ported. Network-specific enhancements or extensions to the X.3 param- eters are available at both the X.29 and the host-based PAD user in- terface. Terminal processes that depend on these extensions may not function correctly when used on other PSDNs or when accessing one PSDN by another, for example, international access. The X.29 interactive terminal interface allows remote asynchronous ter- minals (character-mode DTEs) connected to the network to communicate with the DIGITAL UNIX system in a manner similar to local terminals. The maximum number of terminals supported on a DIGITAL UNIX system (both 5 WAN Support for DIGITAL UNIX Systems V3.0 SPD 42.47.12 local and X.29 remote) cannot exceed the number for which the system has been configured. When using applications designed for interactive, local terminal op- erations, transmission delays or PAD parameter settings can cause in- consistencies between incoming X.29 traffic and the application's op- eration. It may be necessary to make modifications to the application user interface or alter PAD parameter settings. The X.29 interface includes a programming capability for the support of specific X.29 signalling requirements, including modification of PAD parameters. Accounting Accounting information is collected by a dæmon process and is made avail- able to the user by a report writing utility. For incoming X.29 calls, no information can be retrieved relating to the process or account onto which a user is logged. ISDN circuit usage information, detailing B-channel setup and clear- ing is logged and made available by a separate ISDN management util- ity. Security An extensive security facility is provided. Control of remote access to the system (incoming security) and local access to the network (out- going security) are supported. Incoming and outgoing security can be based on any combination of: o Normal or reverse charging o DTE number o Network (PSDN) o Process (or user) making the outgoing call o Application handling the incoming call Network Management 6 WAN Support for DIGITAL UNIX Systems V3.0 SPD 42.47.12 The Network Control Language (NCL) is provided for the management of WAN Support for DIGITAL UNIX and DECnet/OSI. NCL provides X.25 net- work management facilities to: o Define outgoing call destinations o Define incoming call handling o Modify X.25 frame and packet level parameters o Define security parameters o Modify network configuration o Monitor connection statistics o Perform network maintenance functions On DEC 3000 series systems, ISDN is managed by user utilities. An ISDN Hosts database is used to manage call information required to make and receive ISDN calls from remote systems. In addition, utilities are pro- vided for determining the status of ISDN connections, and for forc- ing the closure of unwanted connections. ISDN D-channel activity can be traced using the CTF utility. The network manager can be notified of significant network events such as security violations or network failures through the event logging facility. Problem solving is facilitated by the provision of the Common Trace Facility (CTF). CTF enables the user to trace and analyze frames pass- ing between the PSDN and the WAN Support for DIGITAL UNIX system. Communications Interfaces Refer to the tables in this Software Product Description and to your local hardware service provider for complete information on the syn- chronous controller cards supported by WAN Support for DIGITAL UNIX. In addition to the synchronous controller cards listed in this Soft- ware Product Description, operation over CSMA/CD (ISO 8802/3) and FDDI (ISO 9314) networks is supported through the LLC2 protocol. 7 WAN Support for DIGITAL UNIX Systems V3.0 SPD 42.47.12 Optional Facility Support Table 1 describes the Optional User Facilities of the 1988 ITU/TSS X.25 recommendations that WAN Support for DIGITAL UNIX Systems supports.
