I have a question about the X.25 provided with Cisco systems:
Is the switching of X.25 that cisco boxes can do full level 3
switching, or merely level 2 ? i.e.:

- Do the fragment and fill pakets ?
- Do they run the paket layer sliding window protocol,
  or somply "pass through" the layer 3 pakets ??
- Do they change call request and confirmation pakets according to
  different trunk parameters ?

Any help welcome

(when i look into my news system and see how unstable it is currently,
 i would prefer e-mail).
