X.25 iX Network Link Technical Data
For HP 3000 Series 900 Computer Systems Product Numbers 2340A, 2343D,
2345A, 2346D/E/F/G, D2355A, 36939A
The iX Network Link for HP 3000 Series 900 computers is a
high-performance networking solution that provides Hewlett-Packard
customers access to public and private X.25 packet-switching networks.
It features extensive communications capabilities with remote HP 3000
hosts and asynchronous PAD (Packet-Assembler/Disassembler) devices.
[Figure 1 (X.25 iX Network Link) Caption: none]
The X.25 iX Network Link functions with the Datacommunications and
Terminal Controller (DTC) to provide customers with high-performance
remote communications. The X.25/iX Network Link offers a range of line
speeds and connections depending on the DTC. The DTC16/X.25 iX Network
Link provides a solution for customers with less extensive
communications needs. The DTC48/iX Network Link provides a solution for
customers having higher connectivity needs.
The same DTC being used for X.25 and PAD functionality can also be
used for multivendor, multisystem terminal server connectivity,
providing customers with an integrated communications solution. (Please
refer to the "Datacommunications and Terminal Controller" data sheet for
more information.)
Based on industry standards, the X.25 iX Network Link is an integral
part of the HP AdvanceNet strategy for multivendor communications. It
also provides a programmatic interface for software developers needing
to access non-HP devices.
The X.25 iX Network Link achieves high-performance networking by
offloading protocol processing from the HP 3000 Series 900 host to an
optimized DTC/X.25 Network Access card (in the DTC). This LAN-based
design allows multiple Series 900 hosts to share the same X.25 line,
making cost-effective use of the X.25 network subscription.
A single operator can manage X.25 connections through the use of a
PC-based HP OpenView Windows Workstation. HP OpenView Windows provides
an easy-to-use advanced graphics user interface that simplifies the
management of multiple DTCs.
X.25 iX Network Link Benefits and Features
Extensive host-to-host communications:
o Full support of NS Services (36920A) and ARPA FTP (36957A) for
communications to remote computers across public and private X.25
networks.
o SNA connectivity for HP 3000-to-IBM communications with SNA/X.25
Link/iX, a software product that enables HP SNA Services to be
supported over an X.25 network. Please refer to the "SNA/X.25 Link/iX"
data sheet for more information.
o Programmatic access to X.25 level 3 and TCP level 4 for program
development of special applications such as HP to
non-HP communications.
o Packet routing and gateway capabilities to IEEE 802.3 or
point-to-point subnetworks, achieving higher network transparency.
Cost-effective terminal-to-host communications:
10
o Cost-effective solution for remote PAD terminal and printer access to
HP 3000 Series 900 computers.
o Support of character mode and VPlus block mode applications.
In addition to providing PAD terminal access to the HP 3000 Series 900
computers, the X.25 Network Access card provides PAD terminal access to
HP 3000 MPE V systems (with DTC Extended Switching or TELNET), HP 9000
systems (with TELNET), or non-HP systems (with TELNET). The incoming PAD
call is processed in the DTC. Depending on the designated system, the
DTC will either send out an optimized LAN packet to the HP 3000
Series 900, or will send out a TELNET package to the HP 3000 MPE V,
HP 9000, or non-HP system.
Note: If using a DTC48 for this multivendor PAD access, a memory upgrade
(HP 2348A) to the DTC48 is needed. This upgrade is only needed if the
DTC date code is less than 3110. Please refer to the "Datacommunications
and Terminal Controller" data sheet for more information on these
configurations.
Adherence to standards:
o Open Systems Interconnect (OSI) layered architecture.
o Standard CCITT 1980 and 1984 version of X.25 and 1980 and 1984
versions of X.3/X.28/X.29, and Defense Advanced Research Projects
Agency (DARPA) TCP/IP protocols.
o Compliance with Defense Data Network (DDN) specifications.
High performance:
o High system connectivity with up to 11 X.25 Network Interfaces (NI)
and 1024 virtual circuits per HP 3000 Series 900 host.
o 32 Series 900 hosts can share one DTC/X.25 Network Access card.
o Reduced CPU overhead due to X.25 and PAD protocol processing on the
DTC.
o In addition, multiple cards (either in the same DTC48 or in multiple
DTC16s) are supported for a single IP address for higher throughput
and redundancy. This requires MPE iX Release 2.2 or later.
o Up to 60 X.25 iX Network Links can be managed by a single HP OpenView
Windows Workstation.
Flexible solution:
o Based on connectivity requirement, customers can choose to use either
a DTC48 or DTC16.
o Up to 3 DTC48/X.25 Network Access cards are supported per DTC48. The
DTC48/X.25 Network Access card provides line speeds up to 64 Kbps with
a total of 256 virtual circuits per card. Utilizing the maximum 3
cards, a total of 768 Virtual circuits are available per DTC48.
o 1 DTC16/X.25 Network Access card is supported per DTC16. The
DTC16/X.25 Network Access Card supports line speeds up to 19.2 Kbps
with 32 virtual circuits per card.
Note: The DTC48 cannot support both a X.25 Network Access card and an
HP ARPA Telnet Access Card. Please refer to the "HP ARPA Services/iX"
data sheet for more information.
Ease of use:
11
o Easy-to-use graphical user interface, based on HP OpenView Windows
(32048A) for DTC management, providing better efficiency for network
operators.
High access security:
o PAD terminal and X.25 host access security.
X.25 iX Network Link Components
The X.25 iX Link for HP 3000 Series 900 computers is a networking
solution based on the multivendor Datacommunications and Terminal
Controller hardware and software. It includes:
o DTC/X.25 Network Access
o X.25 iX System Access
o HP OpenView DTC Manager
DTC/X.25 Network Access card resides in the DTC (either DTC16 or DTC48),
and is used to process the X.25 protocols. The necessary software is
downloaded to the DTC across the IEEE 802.3 Local Area Network from the
HP OpenView DTC Manager, which controls the entire DTC from an
HP OpenView Windows Workstation.
DTC/X.25 Network Access card allows connections to be established
with HP 3000 Series 900 hosts across the IEEE 802.3 LAN, using
HP optimized protocols for maximum efficiency. In this way, it provides
cost-effective Series 900 host access to remote X.3/X.28/X.29 PAD users.
When used in conjunction with X.25 iX System Access and NS Services or
ARPA FTP, it features extensive host-to-host communications across X.25
public and private packet-switching networks.
Functional Description of DTC/X.25 Network Access Card
DTC/X.25 Network Access card is a high-performance VLSI card that
implements 1980 and 1984 CCITT X.25 protocols at levels 1, 2, and 3, as
well as 1980 CCITT X.3/X.28/X.29 PAD protocols. The DTC16/X.25 Network
Access card supports signaling rates up to 19.2 Kbps. The DTC48/X.25
Network Access supports signaling rates up to 64 Kbps.
The DTC is a modular device that can accommodate both asynchronous
and X.25 connections. The DTC16 accommodates 1 DTC16/X.25 Network Access
card. This same DTC16 can also accommodate up to 2 asynchronous
connector cards, which allow local and remote asynchronous connections
for terminals and printers.
The DTC48 can accommodate up to 3 DTC/X.25 Network Access cards. This
same DTC can also accommodate several asynchronous connector cards,
which allow local and remote asynchronous connections for terminals and
printers.
Note: DTC48/X.25 Network Access Cards and DTC16/X.25 Network Access
Cards are not interchangeable.
In a configuration without X.25 iX System Access, the DTC/X.25 Network
Access allows remote X.3/X.28/X.29 PAD terminals and printers to
exchange data with any HP 3000 Series 900 computer on the LAN, as
configured by the HP OpenView DTC Manager. Consequently, remote PAD
users can have direct logon access to any HP 3000 Series 900 host.
Access can be either direct, to a single host, or user-selectable to any
host on the LAN, through the DTC user interface.
12
Connectivity of remote X.3/X.28/X.29 PAD terminals to DTC/X.25
Network Access can be restricted using PAD access lists. These lists are
configured by the HP OpenView DTC Manager, and restrict user access to a
predefined list of HP 3000 Series 900 hosts, based on the calling X.25
address. Security on remote X.25 host access is implemented with the
Local User Group utility, which filters incoming and outgoing calls
based on the calling and called X.25 address, respectively.

Functional Description of X.25 iX System Access
X.25 iX System Access is a software product that resides on the HP 3000
Series 900 computer. It implements Defense Advanced Research Projects
Agency (DARPA) TCP/IP at layers 3 and 4 of the OSI reference model, and
interconnects with X.25 layer 3 of the DTC/X.25 Network Access software
across the IEEE 802.3 Local Area Network (LAN). Note that X.25 iX System
Access is not an X.25 protocol implementation, but simply provides an
X.25 addressing and facility interface between the HP 3000 Series 900
computer and the DTC.
An HP 3000 Series 900 host defines a Network Interface (NI) for each
DTC/X.25 Network Access card it uses. Each NI can support up to 11
DTC/X.25 Network Access cards, and up to 11 such NIs can be configured
on the same host.
When used with the NS3000/iX Network Services (HP 36920A) and HP ARPA
FTP Service (HP 36957A), X.25 iX System Access features host-to-host
communications with remote computers. Furthermore, connections
originating from other HP 3000 computers on the same IEEE 802.3 LAN or
from an NS point-to-point network can be transparently routed to the
X.25 network via the IP layer 3 internet protocol.
The X.25 iX System Access product provides programmatic access to
packet level 3 to allow sophisticated users to develop their own
protocols and services for communications with remote HP or
non-HP computers.

Ordering Information
If an available DTC is not already installed, a DTC must be ordered for
operation of DTC X.25 Network Access. Please refer to the
"Datacommunications and Terminal Controller" data sheet for information.
Note: Every DTC must contain at least one asynchronous card for
diagnostics and support.
Ordering the DTC16/X.25 Network Access card for the DTC16
For X.25 or PAD functionality a DTC16/X.25 Network Access card must be
ordered.
The card can be ordered as an option on a new DTC16, or as an add-on
to an installed DTC16. If the card is going to be ordered as part of a
new DTC, the following option on the DTC16 (HP 2340A) should be ordered:
o Option 310 - RS-232 interface
If a DTC16 is already installed on the network, DTC16/X.25 Network
Access is available through HP field installed DTC16/X.25 Network Access
cards.
HP 2343D - Add-on DTC16/X.25 Network Access card: RS-232 interface
Ordering the DTC48/X.25 Network Access card for the DTC48
For X.25 or PAD functionality, between 1 and 3 DTC48/X.25 Network Access
cards must be ordered.
DTC48/Network Access cards can be ordered either as an option on a new
DTC48, or as add-on cards for an installed DTC48. If the DTC48/Network
Access card is to be used in a new DTC, one of the following options
should be included as part of the DTC48 (HP 2345A) order:
Option 310 - RS-232 interface
Option 320 - V.35 interface
Option 330 - V.36 interface
Option 335 - RS-422 interface
If a DTC48 is already installed on the network, DTC48/X.25 Network
Access is available through HP field installed DTC48/X.25 Network Access
cards.
Note: Option #001 must also be ordered if card is installed on a DTC48
containing a date code less than 2851.
Note: If the DTC48 will also be used for accessing TELNET systems, a
memory upgrade may also be necessary. If the DTC48 has a date code less
than 3110, then you should order HP 2348A, which provides additional
memory to the DTC48.
Note: A DTC48 cannot support both an X.25 Network Access card and an
HP ARPA Telnet Access card. The HP ARPA Telnet Access card allows a user
connected to a TELNET system to access applications on the HP 3000
Series 900. Please refer to the "HP ARPA Services/iX" data sheet for
more information.
