PREFACE

This

uanual

contains

installation

and

servicing

information

for

the

HP

30010A

Intelligent

l~etwork

Processor

(IHP).

The

INP

is

a

functionally

flexible,

single-channel

data

processor

that

provides

I/O

capability

between

the

HP

3000

Series

II

or

Series

III

Computer

System

and

other

computer

systems

via

either

modulator/demodulators

(modems)

and

telephone

lines

or

direct

connection.

~his

manual

was

written

with

the

assumption

that

the

reader

has

a

thorough

knowledge

of

the

HP

3000

Series

II/III

I/O

system

and

is

familiar

with

the

latest

data

communications

techniques.

rrhis

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

INP

printed

circuit

assemblies

(PCAs)

and

their

inter-

connecting

cabling

into

an

HP

3000

Series

II

or

Series

III

Coraputer

System.

Section

III,

Programming

Information,

states

the

fact

that

the

INP

is

preprogrammed

and

requires

no

field

programming.

Section

IV,

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

V,

i'1aintenance,

contains

general

servicing

infor-

mation,

troubleshooting

procedures,

repair

instructions,

and

a

description

of

applicable

maintenance

aids.

This

manual

should

be

retained

GENERAL

DESCRIPTION

'IhE·

HP

30010A

Intelligent

Network

Processor

(frequently

referred

tc

hereafter

as

the

!NP)

provides

the

HP

3000

Systerr.s

with

data

ccmmunication

capabilities

in

high-speed

as

well

as

low-speed

mcdem

environments.

A

microprccessor

within

the

!NP

performs

the

communications

protocol

rnanagemer.t,

thus

relieving

the

HP

3000

processor

of

that

task.

As

power

is

applied,

the

!NP

initializes

itself,

runs

a

mini-diagnostic

routine,

reports

to

the

system

that

it

is

functionally

operational,

and

requests

configuration

parameters.

Wher: a

reque·st

for

data

communication

performance

is

made

(for

example,

when

a

user

at

a

terminal

opens

a

DS

line),

the

systerr:

loads

the

appropriate

driver

onto

the

INP.

The

INP

then

t'ransfers

control

to

the

driver

from

its

background

loader

pro-

gram.

The

driver

opens

the

communications

channel

and

passes.

buffered

data

back

and

forth

between

the

HP

300C

CPU

and

the

are

all

performed

by

!NP.

The

CPL

and

cedures.

While

the
