This Recommendation defines the resource connection initiation protocol (RCIP) for signalling
control information between peer TRC-PEs (Rp interface) in a single operator's network. The
requirements for the Rp interface are defined in clause 8.6 of [ITU-T Y.2111] and in
[ITU-T Q.Sup51].
The possible methods of configuration and notification between the transport physical entities
(T-PE) and the transport resource control are out of scope of RCIP. RCIP only specifies the control
plane signalling among transport resource control physical entities (TRC-PEs) in an operator's
network.
