X25 : insertion of call user data (CUD)

Cisco IOS can substitute X.25 calling and called address. For example,

x25 route input-interface s0 source .* substitute-source 888 interface s1

This will change into 888 the calling address of an incoming call from serial 0 and send the call to serial 1.

Do you know if it is possible to modify or insert the call user data CUD of an X25 call and how to do it ?

Example : I want to insert C8C8C8 (hexa) in the CUD of a call with source=666 and dest=777 and send it to interface serial 1

Thanks for any advice

Re: X25 : insertion of call user data (CUD)

Seeing this document, I think it is possible to do the insertion of CUD :

Re: X25 : insertion of call user data (CUD)

Yes it is possible thanks to translation.

However you are restricted by the format of the first four bytes of the call user data called the PID . That is -if you want to insert a 3-byte-long value it will insert a 4-byte-long one with the 4th byte padded with 0s. Same if you put a value which is not 4 or 8-byte long...

there may be a way around this limitation, like specifying the PID length or so ?
