Dokumentacja DSS1 i Q.931 - jak czytać Trace-a (30B+D)?

Question

Może ktoś z userów na jakąś dokumentację dotyczącą DSS1 a szczególnie Q.931. Byłbym wdzięczny za wszelkie materiały najlepiej po polsku lub angielsku. Wiem że ludzie pracujący na centralach nadrzędnych bywali na takich szkoleniach wię może ktoś mi pomoże ( jak powinien wyglądać prawidłowy SETUP,co centrala powinna wysyłać i odpowiadać itp.)

A chodzi mi konkretnie o sposób czyczania i konstrukcji trace-a,żeby ktoś mnie chociarz trochę naprowadził bo teoretycznie to wszystko jest proste a w praktyce to niestety już gorzej. W w/w trace centrala nie może zająć linii, nie jest wogóle podstawiany kanał B, pytanie DLACZEGO???????
Dodałem to samo jeszcze raz w załączniku bo tu się trochę rozsypało.
