PREFACE
This manual contains installation and serv1c1ng information for
the HP 300208 Intelligent Network Processor (INP). The INP is
a functionally flexible, single-channel data processor that pro-
vides I/O capability between the HP 3000 HP-IB Version Computer
Systems and other computer systems via either modulator/de-
modulators (modems) and telephone lines or direct connection. In
this manual, the HP 3000 HP-IB Version Computer Systems refers to
the HP 3000 Series 30,33,40,44 and 64 Computer Systems.
This manual was written with the assumption that the reader has a
thorough knowledge of the HP 3000 HP-IB Version I/O system and
is familiar with the latest data communications techniques.
This manual is organized as follows:
Section I, General Information, briefly describes the main
features of the INP and how it operates. This section also
describes how the INP is configured in the computer system,
lists the equipment supplied with the INP, and lists its
specifications.
Section II, Installation, contains instructions for installing
the !NP printed circuit assembly (PCA) and its interconnecting
cabling into an HP 3000 HP-IB Version Computer System.
Section III, Principles of Operation, is a description of the
hardware operation of the INP and its associated communication
channels. Since this is a brief overview, intended only to
give the user a better understanding of how the INP does its
job, some minor operational details have been omitted.
Section IV, Maintenance, contains general serv1c1ng inform-
ation, troubleshooting procedures, repair instructions, and a
description of applicable maintenance aids.

1-1. INTRODUCTION
This section describes the functional and physical character-
istics of the HP 300208 Intelligent Network Processor (INP)
shown in figure 1-1. Related publications that may be required
for operation and service of the !NP are listed in the Preface.
In this manual, the HP 3000 HP-18 Version Computer Systems refers
to the HP 3000 Series 30,33,40,44 and 64 Computer Systems.
1-2. GENERAL DESCRIPTION
The HP 300208 Intelligent Network Processor (frequently re-
ferred to hereafter as the !NP) provides the HP 3000 HP-!8 ver-
sion Computer Systems with data communication capabilities in
high-speed as well as low-speed modem environments.
A microprocessor within the INP performs the communications pro-
tocol management, thus relieving the HP 3000 processor of that
task. As power is applied, the INP initializes itself, runs a
mini-diagnostic routine, reports to the system that it is func-
tionally operational, and requests configuration parameters.
When a request for data communication performance is made (for
example, when a user at a terminal opens a DS line), the system
loads the appropriate driver onto the INP. The INP then trans-
fers control to the driver from its background loader program.
The driver opens the communications channel and passes buffered
data back and forth between the HP 3000 CPU and the data
communication channel.
Serialization, protocol management, frame/block management, modern
management, and data buffering are all performed by the INP. The
CPU must still process message formats and higher level link pro-
cedures. While the INP is transferring the last correctly
received block of data to the CPU, the INP is also processing and
buffering the next block of data corning from the communication
channel.

The HP 30020B Intelligent Network Processor consists of the
following:
• One
Intelligent
assembly (PCA),
Network Processor (INP)
part number 30020-60009.
printed
• One HP-IB Ribbon Cable,
part no. 30090-60051.
circuit
• One HP 300208 Intelligent Network Processor Installation and
Service Manual, part no. 30020-90005.
• One HP 30010A/30020A/B Intelligent Network Processor Diag-
nostic Procedures Manual, part number 30010-90002.
Although a complete INP subsystem must include one or more INP-
to-modem cables, INP-to-INP direct-connect cables, or INP-to-SSLC
direct-connect cables, these cables are not included under the
HP 300208 product number. Each interconnecting cable or set
of cables required for the various configurations is ordered
separately under its own product number. See table 1-1 for a
list of the available cables.
ICAUTION I
Use of the longer lengths of the
external interconnect . cables
requires special precautions. Long
cables are very susceptible to
induced transients. DO NOT run
cables outdoors or near electrically
"noisy" equipment.
The following test equipment is used to verify the proper opera-
tion of the INP while troubleshooting the data communications
network:
• Cable test connector.
• Board test hood.
These items of test equipment are supplied by the HP Customer
Engineer (contained in Product Support Package 30010-67801).
Different part numbers of test connectors and test hoods are
required for different cable connection configurations. Table
1-2 shows which test items are compatible with each set of inter-
connecting cables.

1-5. Interface to System
The HP 30020B INP has one PCA board that is backplane compatible
with the HP 3000 HP-IB Version Computer Systems. The INP PCA is
installed in the "device" section of the I/O card cage. The INP
communicates with the General I/O Channel (GIC) via connector J3,
and with the modem via connectors Jl and J2. (See figure 1-3.)
The INP receives power from the system via connectors P2 and P4.
Connector Pl is used for test signals, and connector P3 is not
currently used.
