HP Token Ring/9000 for Series 800 Computers Technical Data
Product Number J2166A
HP Token Ring/9000 provides all the necessary hardware to interface
between an HP 9000 Series 800 computer and a Token Ring Local Area
Network. Also included in this link product is networking software
corresponding to Layers 2 through 5 of the Open Systems Interconnection
(OSI) Reference Model and node management software.
Users can choose to write their own user software to access Berkeley
Sockets software provided, or choose one of the higher-level networking
software products provided by Hewlett-Packard.
HP Token Ring/9000 Connectivity
For those users needing multivendor communications, HP Token Ring/9000
can be used with ARPA Services, NFS Services, and LAN Manager/X. ARPA
Services provide de facto networking software as defined by the
Department of Defense Advanced Research Project Agency and the Berkeley
Software Distribution (BSD) UNIX(r) 4.3 system. NFS/9000 allows HP 9000
computers to share file systems in a multivendor network of machines and
operating systems. LAN Manager/X is an advanced full-featured network
operating environment that enables UNIX-based machines to operate as
file and resource servers to MS-DOS(r) and OS/2 PC workstations.

HP Token Ring/9000 Features
o A complete link connection to the Token Ring network, which includes
hardware and transport software
o Full interoperability with IEEE 802.5 and IBM Token Ring
o 4 Mbits/second or 16 Mbits/second burst transfer rate
o Network transport software based on de facto industry-standard Defense
Advanced Research Projects Agency (DARPA) protocols, corresponding to
the transport and network layer functions
o Integrated node management software provides online network
configuration and logging
o Supports Source Routing to remote connections through Source Routing
Bridges configured to use a maximum packet size of 4472 bytes
o Supports HP 9000 Series 800 as LAN-to-LAN router
Hardware Components
The HP Token Ring/9000 adapter card manages packet buffering, processes
IEEE 802.5 protocols, and uses an LED to display the Token Ring adapter
status.
A 9-pin D-type connector on the Token Ring adapter card is used to
connect the adapter to the Token Ring network through a cable that plugs
into a Multi-station Access Unit (MsAU). On a 4 Mbit/second Token Ring
network, the following IBM cable types are supported:
________________________________________________________________________
Data Grade AWG Type
________________________________________________________________________
Type 1 22 2-wire shielded twisted pair
Type 2 22 2-wire shielded or 4-wire unshielded twisted pair
6
Type 3 22, 24 twisted-pair unshielded
Type 6 26 2-wire shielded twisted pair
Type 9 26 2-wire shielded twisted pair
________________________________________________________________________
For Type 3 unshielded twisted pair (UTP), the customer will need to use
a media filter, which attaches to the DB9 connector. This is done for
impedance matching from 150 Ohm (shielded twisted pair) to 100 Ohm UTP.
Additionally, only shielded cables are supported at the 16 Mbit/second
data link rate.
Features
o Uses TMS380C16/04 TI Token Ring communication processor
o Uses 512K bytes of DRAM space for MAC code and datastorage
o Uses frame size up to 4096 bytes
o Supports early token release at 16 Mbits/second
o Supports up to 255 link stations
o Environmental: Class B2
o EMC: complies to FCC A and VDE Level B
Environmental Characteristics

Electrical Specifications
Maximum power consumption is 10 watts at 5 volts.
Software Components
HP Token Ring/9000 includes software corresponding to Layers 2 through 5
of the Open Systems Interconnection (OSI) Reference Model. The link
layer, corresponding to layer 2 of the OSI model, consists of the link
level IEEE 802.5 protocol. Transmission consists of sending addressed
frames of data on the cable at a signaling rate of either 4 megabits per
second or 16 megabits per second.
The Networking Layer, corresponding to OSI Layer 3, is based on the
ARPA Internet Protocol (IP). IP provides fragmentation and reassembly of
data as well as internal addressing.
The Transport Layer, corresponding to OSI Layer 4, is based on the
ARPA Transmission Control Protocol (TCP). TCP provides end-to-end
reliable, connection-oriented services with flow control and
multiplexing. TCP has mechanisms for detecting duplicate, lost, or
out-of-sequence packets. Layer 4 also provides the User Datagram
Protocol (UDP) supported by BSD IPC. UDP provides an unacknowledged
datagram service.
BSD Sockets is an interface between the upper layers and the
product's transport proto-cols. BSD Sockets enable customers to
establish peer-to-peer communications between pro-cesses running on
7
HP 9000 computers and processes running on other systems using BSD 4.2
or later.
The node manager software uses the commands of the nodal management
module to establish computer-to-network connections and to maintain the
network. Network maintenance operations include initialization and
configuration of the networking products, establishing network security,
and using various diagnostic tools to ensure proper network operation.
The diagnostics include loopback verification, nodal statistics,
tracing, and logging.
Installation Policy
Please contact your HP Sales Representative or local HP sales office for
more information on the installation policy of this software product in
your system environment.
Customer Responsibility
HP Token Ring/9000 for the Series 800 is customer installable and
configurable. Installation of HP Token Ring/9000 is the responsibility
of the customer. Prior to installing HP Token Ring/9000, the customer
