[ PR_EF_AC----'E I
Th ism an ua 1 co nt a ins ins tall a t ion and s e r vic in gin form a t ion for
the HP 30020A Intelligent Network Processor (INP). The INP is a
functionally flexible,· single-channel data processor that pro-
vides I/O capability between the HP 3000 Series 30 or ser ies 33
Computer Systems and other computer systems via either mod.ulator /
demodulators (moderns) 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 30 and Series 33 I/O
system and is familiar with the latest data communications
tech·niques.
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 des-
cribes how the INP is configured in the computer system, lists
the equipment supplied with the INP, and lists its
specifica tions.
Section II, Installation, contains instructions for installing
the INP printed circuit assembly (PCA) and its interconnecting
cabling into an HP 3000 Ser ies30 or Series 33 Computer System.
Section III, Progr.amming Information, states the fact that the
INP is preprogrammed and requires no field programming.
Section IV, Pr inciples of cperation, 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, same
minor operational details have been omitted.
Section V, Maintenance, contains general servicing information,
troubleshooting procedures, repair instructions, and a descrip-
tion of applicable maintenance aids.
This manual should be retained and used with related documenta-
tion for theHP 3000 Series 30 or Series 33 Computer System and
the INP. Related' documents include the following technical
