This Recommendation extends the AAL type 2 signalling protocol (capability set i) specified in ITU-T Q.2630.1 to support: the selection of AAL type 2 path according to the requested Path Type as a part of the support of the revised ITU-T 1.366.2 [13]; the AAL type 2 path redirection request; and the modification of AAL type 2 connection resources (i.e. AAL type 2 Link Characteristics routing function; and Service Specific Convergence Sublayer information) during the established phase of the connection.
