The present document provides architecture and functional requirements for business trunking for the Next Generation Network (NGN). It also specifies the protocol requirements for the Next Generation Corporate Networks (NGCNs) to attach to the NGN (in particular the IM CN subsystem) and also any protocol requirements relation to application servers provided in support of business trunking.
Business trunking is a set of NGN capabilities that may be applied to communications between NGCNs using the NGN as a transit.
