The following warning statements (required by country regulatory agencies) are applicable in the countries
indicated.
United States
Federal Communications Commission (FCC) Statement
Warning: This equipment generates, uses, and can radiate radio frequency energy and if not installed and
used in accordance with the instruction manual, may cause interference to radio communications. It has
been tested and found to comply with the limits for a Class A computing device pursuant to Subpart J of
Part 15 of FCC Rules, which are designed to provide reasonable protection against such interference when
operated in a commercial environment. Operation of this equipment in a residential area is likely to cause
interference in which case the user at his own expense will be required to take whatever measures may be
required to correct the interference.
Instructions to User: Properly shielded and grounded cables and connectors must be used for connection to
peripherals in order to meet FCC emission limits. Proper cables are available from IBM authorized
dealers. IBM is not responsible for any radio or television interference caused by using other than the
recommended cables or by unauthorized modifications to this equipment. It is the responsibility of the user
to correct such interference.
CAUTION:
This product is equipped with a 3-wire power cord and plug for the user's safety. Use this power cord in
conjunction with a properly grounded electrical outlet to avoid electrical shock.
Canadian Department of Communications compliance statement
This equipment does not exceed Class A limits per radio noise emissions for digital apparatus, set out in
the Radio Interference Regulation of the Canadian Department of Communications. Operation in a residen-
tial area may cause unacceptable interference to radio and TV reception requiring the owner or operator to
take whatever steps are necessary to correct the interference.
Avis de conformite aux normes du ministere des Communications du Canada
Get equipement ne depasse pas les limites de Classe A d'emission de bruits radioelectriques pour les
appareils numeriques, telles que prescrites par le Reglement sur le brouillage radioelectrique etabli par le
ministere des Communications du Canada. L'exploitation faite en milieu residentiel peut entrainer le
brouillage des receptions radio et tele, ce qui obligerait le proprietaire ou l'operateur a prendre les disp-
ositions necessaires pour en eliminer les causes.

vi V.35 Supplement RPO 800725 and RPO 800726

Chapter 1. Getting Started
V.35 is a communications interface that allows the IBM 5394 to use transmission
speeds of up to 56K bps. A V.35 interface improves the performance of the IBM
5394 Model 01 B.
To use the V.35 interface, you must have one of the following:
• An IBM 5394 Model 01C (RPO 800725)
• An IBM 5394 Model 01 B with a field upgrade (RPO 800726).
Both RPO packages include a V.35 communications cable and a 5394 system
diskette at release level 1.1 or higher.
V.35 Communications Cable
System Diskette and Backup Diskette
RPO 800726 also includes a planar and a nameplate. Ask your customer service
representative to install these new parts.
"V.35 RPO Parts List" on page 26 identifies all unique part numbers.

How to Use This Book
This book is a supplement to the base IBM 5394 Remote Control Unit library. The
chapters in this book are arranged to correspond to the structure of the books in
the base 5394 library. For example:
• Use Chapter 2, Planning for an IBM 5394 with a V.35 Communications Interface
as a supplement to the IBM 5394 Remote Control Introduction and Installation
Planning Guide. This chapter explains how to plan the installation of an IBM
5394 using a V.35 interface.
• Use Chapter 3, Setup and Operation of an IBM 5394 with a V.35 Communi-
cations Interface as a supplement to the IBM 5394 Remote Control Unit Setup
Guide and IBM 5394 Remote Control Unit Operator's Guide and Problem Deter-
mination Procedures. This chapter explains how to set up, configure, and
operate an IBM 5394 with a V.35 interface.
• Use Chapter 4, Maintenance Information for V.35 Communications Interface as
a supplement to the IBM 5394 Remote Control Unit Maintenance Library. This
chapter explains how to service and test the IBM 5394 with a V.35 interface.

2 V.35 Supplement RPO 800725 and RPO 800726

Chapter 2. Planning for an IBM 5394 with a V.35
Communications Interface
This chapter contains information you need to plan a data communications network
using an IBM 5394 Remote Control Unit with a V.35 communications interface.
Use this chapter in addition to the IBM 5394 Remote Control Unit Introduction and
Installation Planning Guide to plan the installation of your IBM 5394.
In this chapter, you can find information about how to:
• Select your system components
• Plan the remote site
• Prepare worksheets.
Planning for System Components
The V.35 communications interface does not affect work station support. For a list
of work stations supported by the IBM 5394, refer to the IBM 5394 Remote Control
Unit Introduction and Installation Planning Guide. You should, however, keep the
following considerations in mind when planning your installation.
The IBM 5394 Remote Control Unit
IBM 5394 Model 01C supports the V.35 communications interface. You can attach
up to 16 work stations to this model. Model 01C also supports the EIA 2320 inter-
face.
