TCP to X.25 Translation

Unanswered Question
Nov 23rd, 2009

Hello everybody

Im using Cisco router as Tcp to X.25 translator. In Tcp to X.25 conversion during X.25 call setup

Cisco router acts as a XPAD device and send call request along with CUD 0X01000000 which

shows source device (Cisco Router) is a PAD device .

Our X.25 remote device just accept X.25 calls from X.25 source , not XPAD so it rejects the call.

How we can force Cisco router to act as a pure X.25 device (not PAD) or send call request without

XPAD CUD.

Thanks

I have this problem too.

Are you using ALP (AirLine Protocol set) or MATIP (Mainframe To IP)?

Hi again,

one thing more.

CUD option just adds cud string to call setup and doesn't omit it.
