Boot to direct mode:
Direct mode is a mode of operation whereby the unit automatically routes APACS 30 packets to their
destination without the terminal having to perform any call control. If this parameter is set to “Yes”,
then the next time the unit is rebooted it will operate in direct mode. For direct mode to work you must
set up the appropriate addressing information (B channel, NUA or NUI). If this parameter is set to
“No”, the unit will still try to use direct mode if it detects that it is required (due to the absence of call
control information). This parameter can be used in certain cases where for some reason the unit
cannot automatically determine whether or not to use direct mode. See also
Disable direct mode
below.
Disable direct mode:
Setting this parameter to “Yes” will prevent the unit from automatically using
Direct mode
(see above) when it receives an APACS 30 packet without any call set-up.
Unable to authorise acquirer response:
This parameter only applies when the unit is operating in direct mode. In cases where the unit is
unable to send the APACS 30 packet to the remote host, it replies to the terminal with an “unable to
authorise” message. By default, this message contains a response code 05 which means declined.
Entering a number for this parameter causes the unit to use that number in place of the default
response code. A value of zero for this parameter prevents the unit from replying.
Transaction delay (ms):
Setting this parameter will cause the unit to pause for the speci
fi
ed number of milliseconds in between
successfully connecting to the remote X.25 host and transmitting the APACS 30 string.
ENQ char delay (ms):
If this parameter is set to “Off”, the unit will send ENQ characters to the locally attached TPAD
terminal when a call has been connected. This parameter may be used to set the delay in ms from
when the router
fi
rst connects the call to when it transmits the ENQ.
Data trigger:
This parameter can be used to generate a “Data Trigger” event (code 47) when the reply from the
X.25 host contains the string speci
fi
ed in this parameter. It is possible to con
fi
gure the unit to generate
an email alert message when this event occurs. See “LOGCODES.TXT” for a complete list of events.
Dialling context:
This parameter is for advanced users only. It enables TPAD transactions to be carried out using the
V.120 protocol. The parameter is used in conjunction with the Polling Answering Service (PANS), and
identi
fi
es which PANS instance is to be used for an outgoing V.120 call. For this to work, the PANS
instance must be bound to a V.120 instance.
Strip Trailing Spaces:
When this parameter is set to “On”, the TPAD instance will look at responses coming from the host
and remove any trailing space characters from the end of the packet before relaying the data to the
terminal. This may be necessary in the host system “pads out” responses with unnecessary spaces
which then cause abnormal behaviour in the terminal.
