ABSTRACT:
Clock recovery is used in a variety of communications network applications to enable nodes using different clocks to operate in an effectively synchronized manner. Example embodiments of the present invention include an apparatus and corresponding method for supporting client data transport with timing transparency and require neither a common clock to be available at both the ingress and egress sides of the connection nor overhead bytes to recover a client clock. Rather, client traffic clock recovery may be performed in example embodiments of the present invention entirely in the egress data path using the client data received from the ingress side after removing the clients signal from a higher level carrier signal.
