IP to X.25 Calls parameters
This page contains a table that allows you to enter a series of IP Port numbers and X.25 Call strings
as shown below. These settings configure the router so that IP data can be switched over X.25. For
example data that is received on a TCP connection can be answered by a PAD as if it is an X.25 call.
This table is duplicated in the
Configure Protocol Switch software ,as the protocol switch feature
also uses this table. It is included at this point in the web user interface as a convenience if you need
to use it for PAD instead of the protocol switch.
Total sockets
Sockets available
These display fields show the total number of sockets available and the number currently free is
shown. Take care to not to allocate too many of the free sockets, unless you are confident other
applications need them.
Port
Used to set up the port numbers for those IP ports that will listen for incoming connections that
are to be switched over X.25 or other protocol. In the case of switching to X.25, when such a
connection is made the router 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.
Number of Sockets
Selects 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
Configuration > Advanced applications > X25 > Macros page.
PID
The protocol ID (PID) to use when the router switches an IP connection to X.25. The PID field
takes the format of four hexadecimal digits separated by commas, such as 1,0,0,0 , at the start of
the Call User Data field in the X.25 call.
