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
example:"
