L
Use TPAD over interface
Selects whether the TPAD instance will use ISDN B-channel X.25, ISDN D-channel X.25, TCP,
VXN or SSL as the transport protocol. For ISDN D-channel operation, select LAPD” option. For
ISDN B-channel operation or operation through a synchronous port, select LAPB. In the case
of LAPB and LAPD an interface number can also be specified. This parameter specifies which
LAPB or LAPD instance to use for the relevant TPAD instance. Select 0 or 1 for LAPB. or 0 or 1
for LAPD. When using LAPB with ISDN, this parameter may be set to 255, which means use any
free LAPB instance. This is useful when more than 2 POS terminals are connected to the
router and the acquirer does not support multiple Switched Virtual Circuits (SVCs) on a single
B-Channel. A value of 254 uses an available LAPB instance, but will use the same ISDN B
channel if two calls are attempted to the same ISDN number at the same time. (All services
that the POS terminals may dial must support multiple SVCs if using the setting 254.)
Use backup interface
Specifies a backup interface used automatically if the call to the primary interface fails. Note
that the primary interface will be tried first for every new call attempt.
