Hello, managers
I have a DECBrouter 90T2 with two wan ports, doing boot Internet
connection (serial 0) and X.25 connection to a PSDN (RENPAC).
Today, we use protocol translation to directly access two Alphas (DEC
3000/800 and 3000/600, DU 3.2). This is done by mapping a X.121 subaddress
to a LAT connection. Users connect from outside to get time forecasts,
satelite images, etc, using a terminal emulator an the zmodem transfer
protocol.
Now I'm panning to remove LAT from the alphas, because I moved the
printer from a terminal server to a print server (a PC running Linux) and
the users do not use serial connections or terminal emulators anymore.
I configured tcp (telnet) translation for other X.121 subaddress (2), as
shown at the last line of this router configuration copy:

200.248.148.2 is the IP address of URANO.
If I make a X.25 call to the address 153231641 I get an immediate LAT
connection, But if I call 153231641 (the subaddress 2) I get a "frozen"
connection:

If I issue a "telnet" command at the router command prompt I get a clean
login.
Thanks for your help.
