Software Product Description ___________________________________________________________________ PRODUCT NAME: VAX ISDN, Version 2.2 SPD 31.23.04 DESCRIPTION The VAX ISDN communication software product allows suitably config- ured OpenVMS VAX systems to connect to ISDN networks based upon the corresponding CCITT Recommendations via a Basic Rate access. Connec- tions are established using the circuit-switched access of the ISDN networks. Table 1 in this Software Product Description (SPD) list the ISDN public networks and switches supported. VAX ISDN is an OpenVMS VAX layered product that provides circuit-switched call control functions. This allows data transfers over one or two B- channels provided by the ISDN network at a Basic Rate access, using the following protocols: o DECnet (Phase IV or Phase V implementation) VAX ISDN allows using DECnet "circuits" to remote DECnet nodes across the ISDN network. Note: A DECnet license is required to communicate with other DEC- net nodes over such circuits. o VAX Packetnet System Interface (P.S.I.) VAX ISDN also allows using X.25 network protocol (VAX P.S.I.) for communication across the ISDN network. o Specific Protocols VAX ISDN also allows using specific network protocols (DDCMP and HDLC) for communication across the ISDN network. DIGITAL November 1993 AE-NS24E-TE VAX ISDN provides the following functions at the VAX node physically connected to the ISDN network: o The ability to support three modes of operation at the controller level. - Simple mode: Calls are set up and cleared whenever explicitly requested either by a system operator or an application program. - Authorized mode: The only difference between this mode and sim- ple mode is that incoming calls that pass the incoming setup in- formation filter are accepted only after they have been explic- itly authorized by an application program. - Time-cutting mode: Automatically establishes a circuit-switched connection to a predefined destination and minimizes circuit us- age cost by automatically clearing a communication when no user or network management data has been transferred for a user-specified length of time. This technique is called "time-cutting." Controller level means both units (each B-channel of the S0 basic rate access corresponds to one unit) must work with the same mode. o The ability for user-written programs running under OpenVMS to con- trol incoming and outgoing calls. The following programming lan- guages are supported: - VAX C - VAX Pascal An ISDN Network Control Program (ISDN$NCP) is provided for manage- ment of VAX ISDN. This interface allows establishing outgoing calls, specifying ISDN addressing information and incoming call filters, accessing statistical information, requesting options or facili- ties and performing maintenance functions (such as setting the op- erating mode). A special security function is provided which allows users to limit the access to ISDN$NCP or ISDN$SA to a limited number of users on the local node or remote users operating VAX ISDN ACCESS. 2 Note: ISDN$NCP and ISDN$SA only support the Phase IV syntax for the node names (six characters). Then, ISDN$NCP and ISDN$SA can only support Phase V node names that have a Phase IV synonym. Problem solving is facilitated by the ability to trace and analyze data transferred between the ISDN network and the various layers of the VAX ISDN software over the D-channel of the Basic Rate ac- cess. ___________________________________________________________________ Table_1:_Public_ISDN_Networks_Supported____________________________ Country_____________Network/Switch_______Supplier_____________Mnemonic France NUMERIS - VN2/VN3 France Télécom NUM Japan INS64 - V2 Nippon T&T Corp.

Three new DCL commands are added to the DCL ta- bles: ISDN CALL, ISDN CLEAR and ISDN SHOW CALLS. Using these com- mands, any user may request the automatic establishment of an ISDN connection and may clear it without knowing the specific parame- ters of the physical unit being used. Before having these commands fully operational on the OpenVMS VAX system, the system or network manager must configure some tables as described in the chapter "Call Management Software" of the Management Guide. o The options and network facilities supported by VAX ISDN vary ac- cording to the local ISDN network in use. Table 3 lists the options that VAX ISDN is capable of supporting. 3 Note: A VAX ISDN ACCESS (SPD 31.24.xx) license is required for control- ling incoming and outgoing calls from remote OpenVMS user programs and for managing the VAX ISDN product from a remote ISDN Network Control Program. Public Networks Supported Table 1 describes public ISDN networks, which are supported with VAX ISDN only in the countries specified. Connections to public networks outside this table are customer supported only. Since the publication of this SPD, other configurations may have been tested. Please consult your local Digital office for any questions con- cerning other public ISDN networks not listed. ___________________________________________________________________ Table 2: Public ISDN Networks Where Qualifications Are in _________Progress__________________________________________________ Belgium Qualification in progress Sweden______Qualification_in_progress______________________________ Unless otherwise acknowledged within the product documentation, the trademarks under which the services are offered are proprietary to the respective national PTT, the owning or operating companies, or equiv- alent organizations. Options and Facility Support VAX ISDN support for any given ISDN option or facility depends on sup- port for it in the corresponding ISDN network. Generally, the VAX ISDN design includes restrictions on the use of options or network facil- ities, and prevents the use of facilities not supported by the local ISDN network. 4 Therefore, Tables 3 and 4 are to be interpreted as what VAX ISDN is capable of using, rather than what it will do when used on any par- ticular ISDN network. The product documentation describes specific op- tions, restrictions, and facilities available for the supported pub- lic ISDN networks. 5 ___________________________________________________________________ Table 3: Options/Facilities ISDN_NETWORK_______________________________________________________ Description_______________________NUM______ATT______DBP_____BT_____ NTT Charging information at end of yes no yes no yes call Incoming address yes no yes no yes Sub-address yes no yes no yes Reverse charging no no no no no User-to-user signaling during yes no no no no call establishment Semi-permanent_Service____________no_______no_______yes_____no_____ no ___________________________________________________________________ Table 4: Options/Facilities ISDN_NETWORK_______________________________________________________ Description_______________________IT_______CH_______SWEDEN_________ Charging information at end of no no yes call Incoming address yes yes yes Sub-address yes yes yes Reverse charging no no no User-to-user signalling during no no yes call establishment Semi-permanent_Service____________no_______no_______no_____________ INSTALLATION Digital recommends that a customer's first purchase of this software include Digital Installation Services. These services provide for in- stallation of the software product by an experienced Digital Software Specialist. 6 Customer Responsibilities In some cases, the ISDN network supplier imposes restrictions, lim- itations, or requirements on the proposed Digital network configura- tion, options, and facilities. The customer must understand and ad- here to these requirements for each and every ISDN network used. Before installation of the software, the customer must: o Previously have installed all prerequisite software and hardware, including terminals. During installation, the appropriate kit (Phase IV or Phase V) is au- tomatically selected from the VAX ISDN distribution media depending on the DECnet version running at that time on the system. However, if the system is upgraded with DECnet/OSI later, the VAX ISDN kit will have to be un-installed (using appropriate command files provided with the product) and re-installed. Digital's Installation Services also require that the customer must: o Have an ISDN Basic Rate Access (S0) line already installed. o Make available for a reasonable period of time, as mutually agreed by Digital and the customer, all hardware, communication facili- ties, and terminals that are to be used during installation.
