In addition test purposes have been defined for implementation dependent behaviour, where at least one of the implementation options is mandatory.

14、Error-Invalid Routing Context“: No statement in RFC 3332 1 clearly outlines its use or applications. A more complete set of torture tests for both ASPs and SGPs shall be provided. 4.1.3 System Under Test In SIGTRAN M3UA, one or more ASP can be contained within an ASP; furthermore, one or more SGP ca

Several scenarios have been envisioned in the present document: - One ASP within the AS. - Several ASPs within the ASP. - One ASP connected to one SGP. - Several ASPs connected to one SGP. 4.2 Over
