15、ecifies the signalling protocol applicable between AAL. type 2 nodes and describes nodal functions that are used to control AAL. type 2 point-to-point bearer connections. The AAL. type 2 signalling protocol specified in the present document is usable in switched and non-switched environments and can
16、 operate in public or private networks over a range of signalling transport protocol stacks. It also provides maintenance capabilities, carriage of user-plane protocol stack information and carriage of an identifier to link the connection control protocol with other higher layer control protocols. T
17、he present document describes the AAL. type 2 signalling protocol that supports the dynamic establishment and release of individual AAL. type 2 point-to-point bearer connections. It also describes the maintenance procedures, the framework of the protocol, and the interactions between an AAL. type2 s
