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 specified 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 “0”, the unit will send ENQ characters to the locally attached TPAD
termi nal when a call has been connected. This parameter may be used to set the delay in ms
from when the router first connects the call to when it transmits the ENQ.
ACK char delay (ms):
This parameter defines the time period the unit will wait for an ACK character to be received
after sending data to the terminal. If an ACK character is not received withing this time the data
will be retransmitted. A value of “0” entered here will defaut to a delay of 1 second.
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 specified in this parameter. It is possible to configure the unit
to gen erate an email alert message when this event occurs. See “LOGCODES.TXT” for a com-
plete 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 identifies 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.
Backup Parameters
Layer 2 deactivation timer (s):
This parameter is functionally equivalent to the Layer 2 deactivation timer parameter in the
gen eral parameters section above but only applies to the backup service.
