The TID will be become inactive in n seconds.
The time, in seconds, before the Terminal ID is considered inactive. Local authorizations may be
configured to occur on active TIDs (terminal Ids), so this parameter defines how long a time
(without transactions) must pass for a TID to change from active to inactive.
Use TID xxxxxxxxx with incoming APACS 50 polling calls
The terminal ID to associate with this TPAD instance when answering an incoming APACS 50
polling call.
Use merchant Number
Inserts a merchant number into the APACS 30 string when the locally connected equipment
does not transmit a merchant number.
Use Connect String
A string sent to the user’s terminal when an outgoing TPAD call has been connected, instead of
the normal ENQ character. For example, you could use this setting to make a TPAD connection
look like a PAD connection by specifying CON COM as the connect string.
The polling character set is c
A string that specifies a character or set of characters to be treated as polling characters. The
router responds to any of these characters using ACK. This parameter should normally be left
blank.
Enable Message Numbering
When enabled, the router overrides the message numbering of the local equipment and
substitute its own message numbering in the APACS 30 data. This is useful when the locally
connected equipment does not automatically increment the APACS 30 message number.
Disable Direct Mode
Enabling this setting will prevent the router from automatically using Direct Mode (see below)
when it receives an APACS 30 packet without any call set-up.
Boot to Direct Mode
Direct mode is a mode of operation whereby the router automatically routes APACS 30 packets
to their destination without the terminal having to perform any call control. If this parameter is
set to Yes, the next time the router is rebooted, it operates in direct mode. For direct mode to
work you must set up the appropriate addressing information, such as Transport protocol,
NUA, NUI, IP address etc. If this parameter is not enabled, the router still tries to use direct
mode if it detects that it is required, due to the absence of call control information. Use this
parameter when the router cannot automatically determine whether or not to use direct
mode.
Use response code n in “unable to authorise” message
This parameter only applies when the router is operating in direct mode. In cases where the
router is unable to send the APACS 30 packet to the remote host, it replies to the terminal with
an unable to authorize message. By default, this message contains a response code 05, which
