PREFACE
This manual contains installation and servIcIng information for the HP 30244M Intelligent Network
Processor (INP). The INP is a functionally flexible, single-channel data processor that provides I/O
capability between the HP 3000 Series 37 Computer System and other computer systems via either
nl0dulator/demodulators (modems) and telephone lines or direct connection.
This manual was written with the assumption that the reader has a thorough knowledge of the HP 3000
Series 37 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
2, Installation, contains instructions for installing the INP printed circuit assembly (PCA)
and its interconnecting cabling into an HP 3000 Series 37 Computer System.
Section
3, Programming Information, states the fact that the INP is preprogrammed and requires
no field programming.
Section 4, Principles of Operation, is adescription 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 5, Maintenance, contains general servicing information, troubleshooting procedures, repair
instructions, and adescription of applicable maintenance aids.
This manual should be retained and used with related documentation for the HP 3000 Series 37
Computer System and the INP. Related documents include the following technical manuals:

INTRODUCTION
This section describes the functional and physical characteristics of the HP 30244M Intelligent Network
Processor (INP) shown in Figures 1-1 and 1-2. Related publications that may be required for operation
and service of the INP are listed in the Preface.
GENERAL DESCRIPTION
The HP 30244M Intelligent Network Processor (frequently referred to hereafter as the INP) provides the
HP 3000 Series ~ ~ Computer System with data communication capabilities in high-speed as well as
low-speed modem environments.
Amicroprocessor
within the INP performs the communications protocol management, thus relieving the
HP 3000 processor of that task. As power is applied, the INP initializes itself, runs amini-diagnostic
routine, reports to
the system that it is functionally operational, and requests configuration parameters.
When arequest for data communication is made (for example, when auser at a terminal opens a DS line),
the system loads the appropriate protocol driver onto the INP. The INP then transfers control to the
driver from its background loader program. The driver opens the communication channel and passes
buffered data back and forth between the HP 3000 CPU and the data communication channel.
Serialization, protocol management,
frame/block management, modem management, and data buffering
are all performed by the INP. The CPU must still process message formats and higher level link
procedures. 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 coming from the communication channel.

General Information
Equipment Supplied
Although the Intelligent Network Processor (INP) is identified by its own product number (HP 30244M),
this
number is used only for internal identification. The INP is marketed as acomponent part of a
hardware/software package called a Network Link. There are five Network Link products available for
the HP 3000/37:
•HP 30246A SNA Link
•HP 3025lA BSC Link
•HP 30270A Point-to-Point (DS) Hardwired Link
•HP 3027lA Point-to-Point (DS) Modem Link
•HP 32187A X. 25 Link
The HP 30244M Intelligent Network Processor consists of the following:
•One Intelligent
Network Processor (INP) printed circuit assembly (PC A), part no. 30244-60002.
•One HP-IB Cable (l foot), product no. HP 92220R.
oOne HP 30244M Intelligent Network Processor (INP) Installation and Service Manual, part no.
30244-90002.
Although acomplete INP hardware 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 30244M product number. Each interconnecting cable (or set of cables) required for the
various configurations is identified separately under its own product number and is included under the
appropriate option number when one of the Network Link products is ordered. See Table 1-1 for alist of
the available cables.
I CAUTION 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.

Interface to System
The HP 30244M INP consists of one PCA board that is backplane compatible with the HP 3000
Series 37 Computer System. The INP PCA is installed in the main card cage or in the card cage of the
optional Extender Box. The INP communicates with the Peripheral Interface Channel (PIC) through the
HP-IB Cable via connector J3, and with the modem via connector J1. (See Figure 1-3.)
The INP receives power from the system through connector P2. Connector PI is used only for test signals
during the manufacturing process and is not to be used during normal operation.
