Hi Everyone,
I'm trying to configure a 1841 Router to do a translate between one central running X.25 (EWSD) and a client running TCP/IP.
The PVCs between the central and the router are ok, but when i try to telnet the central i don't receive and response.
telnet 1.1.1.2 2001
I put my conf below...
If someone see some mistake in my conf or point me some link usefull to start a troubleshooting i will be apreciate that
Thanks in Advanced,
Andre Lomonaco

Whoops I had read badly. Please take debug x25 and debug translate when telnetting from a PC.

Please configure SVC range (incoming/outgoing bidir) according to connected device.

Hi Bevilacqua,
First, thanks a lot for your reply..
Can you explain in more detail what i should do ?
You can see in my configuration i have already define the PVCs range between 1 and 4
when i used the command x25 ltc 5.
I wanna use only this 4 PVCs, I don't wanna use SVCs..
First again and my best regards,

Hi, it seems to me that trouble begins when router sends:
*May 13 17:31:54.621: Serial0/0/1: X.25 O D1 Reset (5) 8 lci 1
*May 13 17:31:54.621: Cause 29, Diag 115 (Network out of order (PVC)/International link out of order)
Can you try:
x25 lic 0
x25 ltc 0
x25 loc 0
to eliminate SVCs altogether. Take debug again. Post it here if different from before.
