Software Product Description ___________________________________________________________________ PRODUCT NAME: Compaq X.25 for OpenVMS Alpha Systems, V1.5 SPD 47.37.13 DESCRIPTION Compaq X.25 for OpenVMS Alpha Systems enables appropriately config- ured systems to connect to an X.25 Packet Switched Data Network (PSDN) via an X.25 Relay node on the same Local Area Network (LAN), via a DNA Phase IV X.25 connector node, or directly using a synchronous controller card. The product supports communication via 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. Compaq X.25 for OpenVMS Alpha Systems also provides the device drivers and specific data link protocol support for Compaq Computer Corpora- tion's synchronous communications options for OpenVMS Alpha systems. Compaq X.25 for OpenVMS Alpha Systems software allows an OpenVMS Al- pha system to: o Connect to other X.25 implementations using RFC 1613 (also known as XOT) via a TCP/IP wide area network. o Act as a Gateway Access Protocol (GAP) server for Phase V GAP Clients o Act as an X.25 Connector system for DECnet-Plus X.25 Access sys- tems 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. January 2001 o Act as an X.25 Relay node conforming to ISO Technical Report 10029. o Provide an X.25 sub-network for DECnet-Plus CONS and CLNS opera- tion. o Provide a DEC-HDLC point-to-point data link for DECnet-Plus CLNS operation. o Act as a combination of the above, chosen on a per-DTE basis. The following restrictions of Compaq X.25 for OpenVMS Alpha Systems software should be noted: o Phase IV GAP Clients (or access nodes) are not supported. o P.S.I. Access (Phase IV) clients are not supported. o DCE mode is supported for the purposes of point-to-point operation as described in ISO 8208; DCE mode for emulation of a PSDN is not supported. o Use of the D bit in data packets is not supported. Compaq X.25 for OpenVMS Alpha Systems supports the following func- tions: o Process-to-process (Compaq X.25) communication. X.25 for OpenVMS Alpha allows application programs to access X.25 network services via the standard OpenVMS QIO system service. o Process-to-terminal (X.29) communication. Through the X.29 QIO programming interface, users of the OpenVMS Alpha system may make outgoing calls to other Compaq or non-Compaq systems or suitable network PADs accessible via a PSDN. o Terminal-to-process (X.29) communication. Remote terminals connected to the PSDN may access the OpenVMS Al- pha host running X.25 by means of an X.29 Switched Virtual Circuit (SVC) call. o DECnet-Plus Connectionless Network Service. The product supports the use of the DEC-HDLC and X.25 protocols as sub-networks for the OSI Connectionless-mode Network Service (CLNS). 2 o DECnet-Plus Connection Oriented Network Service. The product supports the OSI Connection Oriented Network Service (CONS) for OSI Transport over X.25 sub-networks. o X.25 Mail. The X.25 Mail utility allows communication across a PSDN via elec- tronic mail between two systems running the Mail-11 protocol over X.25. Systems that support Mail-11 over X.25 include WAN Support for Compaq UNIX[R], X.25 for OpenVMS Alpha, and X.25 installations of DECnet-Plus for OpenVMS VAX. o Wide Area Network (WAN) Device Drivers The WAN device drivers support synchronous communications and of- fer a supported user ($QIO) interface. This version also includes a pseudodriver (WANDRIVER) that provides a programming interface to the Data Link level for the LAPB, DEC-HDLC, and LLC2 protocols and an interface to the physical layer of the synchronous commu- nication devices supported by the product. o X.25 Relay allows an appropriately configured Alpha system to re- lay X.25 packets between a Local Area Network (LAN) and a synchronous communications link to a Packet Switched Data Network (PSDN). o X.25 GAP Server allows remote Phase V GAP clients to connect to a PSDN via the GAP Server node using the DECnet NSP protocol. The re- mote X.25 client (or access node) communicates with the X.25 Server or X.25 Gateway/Connector node using the Gateway Access Protocol (GAP) via a DECnet session connection. o The multi-host mode of operation provides the features offered by VAX P.S.I. Native and also allows VAX P.S.I. Access systems to con- nect to a PSDN as though directly connected. o XOT or X.25 over TCP/IP allows X.25 applications on an appropri- ately configured Alpha System to communicate with other RFC 1613 implementations over a TCP/IP Wide Area Network. 3 Features Conformance to Standards Compaq X.25 for OpenVMS Alpha Systems complies with the following stan- dards: o ITU/TSS recommendations-X.25 (1980, 1984, or 1988), X.3, X28, X.29 o International standards ISO-8208, 7776, 8881, 8802/2, 8878, 8473 Virtual Circuits Compaq X.25 for OpenVMS Alpha Systems offers communication over both Permanent Virtual Circuits (PVCs) and Switched Virtual Circuits (SVCs), and supports up to 4096 virtual circuits per system. One virtual cir- cuit is used for each incoming or outgoing X.29 terminal connection, for each X.25 call, and for each DECnet-Plus routing circuit and trans- port connection. The use of PVCs for X.29 communication is not defined by the 1980 and 1984 ITU/TSS recommendations, and is not available with Compaq X.25 for OpenVMS Alpha Systems. Virtual circuits may use X.25 protocol over a LAN connection, over a WAN synchronous communications connection, or may use DIGITAL X.25 Client for OpenVMS Alpha Systems over a DECnet circuit to a DECnet Gateway Access Protocol (GAP) connector node. NOTE that there is no support for use of more than 512 of the available virtual circuits by DIGITAL X.25 Client for OpenVMS Alpha Systems with DECnet Gateway Access pro- tocol connector nodes. See the HARDWARE REQUIREMENTS section for de- tails of GAP connector nodes and ISO relay nodes supported. Process-to-Process Communication The Compaq X.25 for OpenVMS Alpha Systems programming interface al- lows application programs to access X.25 packet level services via the standard OpenVMS QIO interface. Functions include the establishment and clearing of network connec- tions, data transmission and reception, sending and receiving of in- terrupt messages, and resetting of virtual circuits. The interface also 4 provides for the segmentation and recombination of messages that are longer than the packet size selected for the circuit. This interface enables an application program using OpenVMS System Ser- vices to communicate with complementary X.25 software on other Compaq or non-Compaq systems. 5 Terminal Communications Compaq X.25 for OpenVMS Alpha Systems supports terminal communica- tions according to ITU/TSS recommendations X.3, X.28, and X.29. Only those terminal parameters defined in the X.3 recommendation are ex- plicitly supported. Network-specific enhancements or extensions to the X.3 parameters are available at both the X.29 programming and the host- based PAD user interface. Terminal processes that depend on these ex- tensions may not function correctly when used on other PSDNs or when accessing one PSDN via 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 OpenVMS Alpha system in a manner similar to local terminals. The maximum number of terminals supported on a OpenVMS Alpha system (both 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 and is made available to the user via 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. 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: 6 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 The Network Control Language (NCL) is provided for the management of Compaq X.25 for OpenVMS Alpha Systems and DECnet-Plus. NCL provides network management facilities to: o Define outgoing call destinations o Define incoming call handling o Modify X.25 frame and packet levels parameters o Define security parameters o Modify network configuration o Monitor connection statistics o Perform network maintenance functions 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 Common Trace Facility (CTF) pro- vided with the OpenVMS operating system. CTF enables the user to trace and analyse frames passing between the PSDN and the X.25 \for OpenVMS Alpha system. In V1.5, the Common Trace Facility (CTF) for OpenVMS Al- pha X.25 functionality has been updated to match the functionality of PSI Trace for the OpenVMS VAX X.25 product. This includes the follow- ing capabilities: o The ability to trace a circuit given the NWA device name o The ability to trace an X.29 port 7 o The ability to trace an individual X.25L3 circuit Communications Interfaces Refer to the tables in this Software Product Description and consult your local hardware service provider for complete information on the synchronous controller cards supported by Compaq X.25 for OpenVMS Al- pha Systems, as well as a list of the relay/connector nodes that may be used as X.25 gateways to the LAN. In addition to the devices listed in this Software Product Descrip- tion, operation over CSMA/CD (ISO 8802/3) and FDDI (ISO 9314) networks is supported via the LLC2 protocol or via TCP/IP using RFC 1613. Wide Area Network (WAN) Device Drivers The WAN device drivers included in X.25 for OpenVMS Alpha Systems sup- port synchronous communications. The device drivers all offer a sup- ported user ($QIO) interface. The device drivers all support full-duplex HDLC framing. In all cases, the data throughput over the synchronous lines is de- pendent on the user applications and system environment. The device drivers support modem control signals (DTR, DCD, DSR, RTS and CTS) where these signals are provided by the selected electrical interface. Supported controllers are listed in Table 4. WAN device drivers include a pseudodriver (WANDRIVER) that provides a programming interface to the Data Link level for the LAPB, DEC-HDLC, and LLC2 protocols. The pseudodriver also provides an interface to the physical layer of the synchronous communications devices supported by the product. The physical layer interface provides the ability to read and write HDLC formatted frames (leading/trailing flag, HDLC frame check sequencing, HDLC bit stuffing), but protocol interpretation of the frames must be provided by the user application using the interface. Optional Facility Support 8 Table 1 describes the Optional User Facilities of the 1988 ITU/TSS X.25 recommendations that Compaq X.25 for OpenVMS Alpha Systems supports. Support for any facility is dependent on the PSDN used.
