Definition of remote TS applications for openFT-FTAM

In order to use the Transport Name Service, CMX must be installed and operation with CMX and TNS must have been explicitly activated in the operating parameters, e.g. using the command ftmodo -tns=y -cmx=y. Alternatively, in the openFT Explorer you can open the Administration menu and choose the Operating Parameters command and then go to the Protocols tab and enable the options Use TNS and Use CMX

In the case of all partner systems that can be accessed via TCP/IP or X.25 , no TNS entries are required since you can specify the partner address directly or enter it in the partner list.

The presentation/session and transport selector entries can be made in ASCII (A'...'), EBCDIC (E'...'), TRANSDATA format (T'...') or hexadecimal (X'...'). Presentation and session selectors may only be between 0 and 16 bytes long. If the presentation or session selector is missing, on Unix systems the entries PSEL V'' or
SSEL V'' are absolutely necessary and on Windows systems it is essential to specify Empty format. On Unix systems with transport addresses for FTAM partners, no CC list may be specified.

If a partner has different addresses for inbound and outbound requests, to simplify administration you can define a dummy entry containing the incoming sender address for the inbound side. To do this you enter a "#" (hash), followed by a number in part 5 of the global name.

Special points (Unix systems)

The entries of the file to be translated with tnsxcom must in principle look the same as in the following examples in section “Sample entries for FTAM partners (Unix systems)”. You can use the following checklist to assist you.

Checklist

The following checklist is intended to help you gather the data required for the TNS entry of an FTAM partner. The questions must be answered by the FTAM partner.

1. openFT-FTAM sets up the connection.

   Which values do the following parameter have (with specification of coding):

   a)	called LAN address	_____________________
   b)	called TSEL	_____________________	Code:	_______________
   c)	called SSEL	_____________________	Code:	_______________
   d)	called PSEL	_____________________	Code:	_______________
   e)	Protocol Identifier (Layer 3 CUD)	_____________________
   f)	called APT	_no _____NILAPTitle __1)
   g)	called AEQ	_no ________________ 1)
   h)	calling APT	_no _____NILAPTitle __ 1)
   1)APT (Application Process Title) and AEQ (Application Entity Qualifier) are not specified in the TNS entries, but in the openFT commands. Some FTAM partners expect APTs and possibly AEQs; others expect no APTs/AEQs to be specified.

2. The partner sets up the connection.

   Which values do the following parameters have (with specification of coding):

   a)	calling LAN address	_____________________
   b)	calling TSEL	_____________________	Code:	________________
   c)	calling SSEL	_____________________	Code:	________________
   d)	calling PSEL	_____________________	Code:	________________

You must observe correct notation (uppercase and lowercase) and remember that blanks and X‘00‘ must be specified correctly for selectors.
