Confi gure > TANS > TANS n 4.93
TANS (TPAD Answering) enables the unit to answer incoming modem calls and to present a TPAD
session to the calling device. The unit will then open a TPAD session to a host, and relay the trans-
action from the modem to a host, and the response from the host back to the modem.
In order for TANS to function, the PSTN modem or an ASY port connected to an external modem
must be bound to the TANS protocol.This is done on the Configure > Protocol Bindings page
or by using the bind command. You may also bind TANS to an ADAPT instance to answer incoming
V.120 calls. This can only be done using the bind command.
Using the Web Page(s)
IP address:
The IP address of the host to connect to. This can be overridden on the Configure > PSTN
page.
IP port:
When making a TCP socket connection, this parameter must be used to specify the TCP port
number to use. This can be overridden on the Configure > PSTN page.
IP length header:
When making a TCP socket connection, this parameter may be used to specify the length of
trans action data in a header packet.
SSL:
When this parameter is set to “On” the unit will connect to the host using SSL. This can be
overrid den on the Configure > PSTN page.
DTE listening port:
The TCP port to listen onto and provide a TANS interface to. This parameter is normally left
uncon figured as normal operation is via ASY ports, but can be useful for devices that can answer
many modem calls and place the asynchronous data onto TCP sockets.
XOT mode:
When this parameter is set to “On”, X.25 XOT mode is enabled on the network side, so that
instead of opening ordinary TCP sockets to transfer the data, an X.25 XOT call is used instead.
X25 call macro:
This parameter defines the X.25 macro to use when making outgoing XOT calls. Its value
should match a name in the table on the Configure > X25 > Macros page.
Init$ 1:/Init$ 2:
These parameters define initialisation strings to be sent to the modem when TANS is bound to
an ASY port, and the ASY port is connected to a modem.
Re-initialise timer(s):
This timer enables a periodic reinitiallisation of any modems attached to the unit.
Modem dumb mode:
When this parameter is set to “On”, the unit will determine the modem’s connection status by
look ing for DCD signals only. If a dumb modem is not connected, it is recommended that this
parame ter be set to “Off”.
