6.2 X.25 to TCP Routes
When a call request is received from the peer X.25 host, the route table is scanned in canonical order
for the first matching entry, using the inbound X.25 connection parameters to compare to the inbound
X.25 call request. When a match is found, the outbound TCP connection parameters of the matched
route entry are used to construct the TCP connection request to the remote IP host. When the remote
IP host accepts the connection, the X.25 call will be accepted, and the gateway connection between the
TCP socket and X.25 logical channel is then ready for data transfer using the conversion method
specified in the route entry.
When a PVC route is set up, the TCP/IP connection will be automatically established before the PVC is
opened.
The required parameters for a TCP/IP to X.25 route are:
●
X.25 Connection Type (SVC or PVC)
●
X.25 Interface (Device)
●
TCP Data Encapsulation Type
●
IP Address of remote TCP/IP host
●
TCP port of the remote TCP/IP host
