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.
