Using the Web Page(s)
Each Configure > X25 > IP->X25 Calls > Entries page contains a table that allows you to enter a
series of IP Port numbers and X.25 Call strings as shown below. It is used to configure the unit so
that IP data can be switched over X.25.
IP Port
The IP Port field is used to setup the port numbers for those IP ports that will “listen” for
incoming connections that are to be switched over X.25. When such a connection is made the
unit will make an X.25 Call to the address specified in the X.25 Call field. Once this call has
been connected, data from the port will be switched over the X.25 session.
# Sockets
The # Sockets field is used to select how many IP sockets should simultaneously listen for data
on the specified port. The number of available IP sockets will depend on the model you are
using and how many are already in use (see note below).
X25 Call
The X.25 call field may contain an X.25 NUA or NUI or one of the X.25 Call Macros defined
on the Configure > X25 > Macros page.
PID
The PID (Protocol Identifier), field specifies the PID to use when the unit switches an IP con-
nection to X.25. The PID (protocol ID) field takes the format of four hexadecimal digits sepa-
rated by com mas, e.g. 1,0,0,0, at the start of the Call User Data field in the X.25 call.
Confirm Mode
When confirm mode is set to “On” then the TCP socket will not be successfully connected
until the corresponding X.25 call is answered. The incoming TCP socket will trigger the cor-
responding X.25 call and if this call is being switched out then the TCP socket will not be
answered until the X.25 call accepted is received. The effect of this mode is that the socket will
fail if the X.25 call fails and so may be useful in backup scenarios.
