INTRODUCTION                                                 14 Jun 83


1.0  INTRODUCTION

This document supplements the TOPS-20  PSI  manuals  by  pointing  out
hints and potential problems discovered at the last minute.


                                 NOTE

               READ  THIS  FILE  BEFORE  STARTING   THE
               INSTALLATION,  SINCE IT CONTAINS CHANGES
               TO THE INSTALLATION PROCEDURE.





2.0  INSTALLATION INFORMATION

2.1  Typing In Installation Parameters

All installation parameters should be typed using  uppercase  letters.
This  is  particularly important for the destination object of Step 24
and the passwords in Steps 24 and 43 of the TOPS-20  PSI  Installation
Guide.



2.2  DTE Addresses

In  the  installation  procedure  as  described  in  the  TOPS-20  PSI
Installation  Guide,  you must specify the DTE address assigned to you
by your PPSN (see Sections 1.4.3, Step 24 of 3.1.2,  and  Step  43  of
4.3).   In  some countries, you must supply the full international DTE
address.  In others,  you  specify  only  the  national  number.   The
national number does not include the country code.

In the United States you are connected to Telenet and you must specify
the  full international DTE address.  The first 4 digits must be 3110.
The next ten digits are divided into two fields:  the Area Code  Field
and the DTE Address Field.  The Area Code Field is a three digit field
modeled after the telephone network style area code.  For example,  in
Boston,  Massachusetts, it is 617.  The DTE Address Field is from 1 to
5 digits assigned by Telenet.  You must expand this field to 5  digits
by  supplying leading zeroes.  For example, if your Area Code Field is
202 and your DTE Address Field is 32, the DTE address which you supply
during the installation procedure is 311020200032.

In France you are connected to  Transpac  and  you  must  specify  the
national  number  only.   The  first digit is 1 followed by an 8 digit
field assigned to you by Transpac.   For  example,  if  your  Transpac
assigned  number is 94000725, you supply 194000725 for the DTE address
during the installation.  Note that 208, which is the country code for
France, is not included.

In Germany you are connected to  DATEX-P  and  you  must  specify  the
TOPS-20 PSI Beware File                                         Page 3
INSTALLATION INFORMATION                                     14 Jun 83


national number only.  This is a string of up to 11 digits supplied by
DATEX-P.  The first digit  is  always  a  4  indicating  the  national
network  is  DATEX-P  and  the second is always a 5 indicating an X.25
port.  An example of a DTE address for DATEX-P is  45611023456.   Note
that 262, which is the country code for Germany, is not included.



2.3  Using The DMC/DMR Line Device

If you wish to use a DMC/DMR for the DECnet line,  you  must  restrict
the  executor  maximum  address to 140 or less and the executor buffer
size to 290.  After completing Step 24 of the installation  procedure,
issue the following X25GEN commands in this order:

     DEFINE EXECUTOR MAXIMUM ADDRESS 140
     DEFINE EXECUTOR BUFFER SIZE 290




2.4  European Sites And 50Hz.

If you are a European site,  immediately  following  Step  31  of  the
installation procedure, you should do the following so that the timers
in the front-end run at 50Hz:

     $RENAME DN20:RSX11S-50HZ.TSK (to be) DN20:RSX11S.TSK




2.5  Loopback Test

When performing the LOOP LINE command of Step 64, do not use  a  COUNT
greater  than  1000  or a LENGTH greater than 127.  Failure to observe
this restriction may cause the loop test to take longer  than  network
management's timeout period of 3 minutes.

If in response to the LOOP command, you receive the message:

       Loop Line Failed, Operation failure
       Timed out waiting for response

you will have to reload the DN20  before  the  DN20  will  respond  to
network  management  commands.   You will receive this response if the
loop test  takes  longer  than  3  minutes  or  if  the  line  is  not
operational.   If the line is functioning properly, this response will
not occur.

The first paragraph on page A-2 should read:

"current port state to 3  (LISTENING).   Note  that  there  are  other
 subroutines  that  upon  successful  execution change the port state.
 When one of these subroutines has been successfully executed, you  do
 not  need  to  execute  X25RPS  to  determine  the  port  state.  For
 example:"

The second paragraph on page B-4 should read:

"After accepting the incoming call, the program has updated  its  copy
 of  the  current port state to XS%RUN (RUNNING).  Note that there are
 other subroutines that upon  successful  execution  change  the  port
 state.  When one of these subroutines has been successfully executed,
 you do not need to execute X%RPS to determine the  port  state.   For
