7 HP ISDN Link/S700, Technical Data For HP 9000 Series S700 Product Number J2104A What Is ISDN? ISDN is an evolution of the telephone network. It provides digital transmission of voice, data, and image on the same physical line. The ISDN Basic Rate Interface (BRI) is a line with 2 x 64 kb/s digital channels, named B (Bearer) channels, which can simultaneously transmit voice, user data, or images in a circuit-switching mode. [Figure: HP ISDN Link/S700, caption: none] ISDN circuit switching provides users with several advantages: o Possible cost-savings for datacommunication (pay for call duration, not for volume), in particular for file transfer over wide area networks. o 64 kb/s reliable data transmission over each ISDN B channel, o Fast dial-up call establishment, o Flexible bandwidth allocation by opening one or several 64 kb/s circuits, o Access security, by identifying callers. HP ISDN Link/S700 The HP ISDN Link/S700 product for the HP 9000 Series 700 provides a network connection on the HP 9000 S700 to public or private ISDN networks. This product allows HP S700-to-HP S700, as well as HP S700 to HP ISDN Server (P/N J2101A), communications over ISDN networks, through the use of the de facto standard TCP/IP. The HP 9000 S700 workstation connected to the ISDN network can communicate with any HP or non-HP system that implements the TCP/IP protocol and is connected to a LAN equipped with an HP ISDN Server. Also, when ordered with option 099, the HP 9000 S700 workstation equipped with an ISDN Link can act as a nondedicated IP router for the other HP or non-HP stations attached to the LAN. Major Benefits 1. Minimum communication costs ISDN tarification is based on the telephone tariffs system. The cost is related to the duration of the call rather than the volume of data transferred. This enables the HP 9000 S700 workstations, equipped with the HP ISDN Link/S700, to cost-effectively transfer information to remote, distributed sites. In addition, built-in features like programmable inactivity timers and multiplexing of multiple sessions over the same B channel allow the user to effectively minimize the communication costs. 2. Transparency for the enduser Because the ISDN Link/S700 is based on the TCP/IP standard, any HP-UX application running on top of TCP/IP can transfer information to remote workstations or computers over ISDN, transparently. ISDN call setup and call clearing are also entirely automated based on the contents of the configuration files. 3. Flexible bandwith allocation 8 One or two 64 kbps B channels can be allocated for a single ISDN communication between two HP 9000 S700 workstations or between one HP 9000 S700 workstation and one HP ISDN Server. File transfers can therefore be performed at up to 128 kb/s. 4. Network security A list of authorized ISDN callers can be configured for the HP 9000 S700 workstation, and calls from unauthorized callers are refused. 5. Centralized management through HP OpenView Node Manager The HP ISDN Link/S700 can be configured and controlled from a remote HP OpenView Node Manager station. It supports the SNMP network management protocol. Product Description The HP ISDN Link/S700 includes all the necessary hardware and software to connect an HP S700 workstation to the ISDN and run TCP/IP based networking software such as ARPA Services, Berkeley Sockets, LAN Manager, or HP's Network Services. These networking software products are not part of the HP ISDN Link/S700 product and are either provided with the HP S700 workstation or must be purchased separately. The hardware includes an ISA/EISA compatible Basic Rate Interface card with its ISDN cable (RJ45 connectors) to connect to the public or private ISDN line. Software is provided on CD-ROM or DAT. A specific software option must be purchased to allow the HP ISDN Link/S700 to act as a local, non-dedicated, IP router/gateway for the workstations and computers connected to the LAN. The HP ISDN Link/S700 is fully compatible with the HP ISDN Server (J2101A). When multiple, distributed HP 9000 S700 workstations need to access a central site over an ISDN network, it is recommended to use the HP ISDN Server to act as a call concentrator for the remote stations to access the computers on the central site LAN. For more information about the HP ISDN Server (Product reference : J2101A), please contact your local HP Sales Representative.
