Abstract
The present invention provides systems and methods for mapping synchronous input signals, such as synchronous Ethernet, into Generic Framing Protocol (GFP) frames for using GFP directly on Optical Transport Network (OTN) while preserving the synchronous timing of the input signals. The present invention defines a mapping technique for GFP-based encapsulation that preserves timing information of an incoming client signal. The mapping technique makes use of the concept that a timing signal can be fractionally multiplied in frequency using factors that are ratios of integers without creating significant timing impairments.
