Acknowledge TPAD data packets
This parameter causes the unit to acknowledge TPAD data packets from the terminal. This
parameter should normally be enabled. Note that this parameter is only used if no polling
characters (see above) are defined.
Convert leading STX character to SOH
Enabling this parameter will cause the unit to convert the leading STX character in a
transaction to an SOH character.
Terminate TPAD call is EOT only
A TPAD call is normally terminated with a DLE EOT sequence. Some terminals only require
the EOT character on its own. If this is the case then enable this parameter.
Clear TPAD call if there is no response to a TPAD transaction request for x seconds
This is the length of time in seconds that the unit will wait for a response to a TPAD
transaction request before clearing the TPAD call.
Generate an event when a TPAD transaction takes longer than x seconds
Setting this parameter to a non-zero value causes the unit to generate an “Excessive
Transaction Time” event (code 56) each time a TPAD transaction takes longer that the
specified number of seconds. This could be used in conjunction with an appropriate Event
Handler configuration to generate email alert messages or SNMP traps when TPAD
transactions take longer than expected. See Configuration - Alarms > Event Logcodes
for a complete list of events.
When the transaction time exceeds x milliseconds, increment the "SLA
Exceptions" statistic
When the total transaction time exceeds the value (in ms) set in this parameter, the NB SLA
exceptions statistic on the Diagnostics - Statistics > TPAD page is incremented. This statistic
can be viewed on the CLI interface by entering the at\mibs=tpad.n.stats command,
where n is the TPAD instance.
Clear the call x seconds after receiving a response
This parameter defines the time period for which the socket closing or the X.25 call clearing
is delayed by after the TPAD session has finished. For example, if this parameter is set to 10
then 10 seconds after the TPAD session is finished (NO CARRIER is seen on the ASY TPAD
port) the network call (X25 or TCP socket) is cleared. The number “1” is a special value. If
set to the number “1” the call will be cleared immediately (not after 1 second).
If the terminal dial command specifies V.120 use PANS context x
This parameter is for advanced users only. It enables TPAD transactions to be carried out
using the V.120 protocol (“ATDV” command). 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 Rate Adaption
instance.
