Generic Framing Procedure (GFP) is a multiplexing technique defined by ITU-T G.7041. This allows mapping of variable length, higher-layer client signals over a circuit switched transport network like OTN , SDH / SONET or PDH .
Transport of a timing transparent transcoded (compressed) 1000BASE-X signal [8] or a stream of packets (such as Ethernet, MPLS or IP) using Generic Framing Procedure: ODU1: 2.49877512605042: Transport of two ODU0 signals or a STS-48/STM-16 signal or a stream of packets (such as Ethernet, MPLS or IP) using Generic Framing Procedure. ODU2: 10. ...
Other recent SONET/SDH enhancements include Link Capacity Adjustment Scheme (LCAS), and the Generic Framing Procedure (GFP). In conjunction with LCAS and GFP, Virtual Concatenation gives the advantage of splitting the required bandwidth equally among a set number of sub paths called Virtual Tributaries (VT).
Virtual concatenation leverages the X.86 or Generic Framing Procedure (GFP) protocols in order to map payloads of arbitrary bandwidth into the virtually concatenated container. The Link Capacity Adjustment Scheme (LCAS) allows for dynamically changing the bandwidth via dynamic virtual concatenation, multiplexing containers based on the short ...

A common practice in telecommunications, for example in T-carrier, is to insert, in a dedicated time slot within the frame, a noninformation framing bit that is used for synchronization of the incoming data with the receiver. In a bit stream, framing bits are predictable (do not carry information), and occur at specified positions in the frame ...
This still leaves enough spare 10-bit odd+even coding pairs to allow for at least 12 special non-data characters. The codes that represent the 256 data values are called the data (D) codes. The codes that represent the 12 special non-data characters are called the control (K) codes. All of the codes can be described by stating 3 octal values.
CRC-based framing is a kind of frame synchronization used in Asynchronous Transfer Mode (ATM) and other similar protocols. The concept of CRC-based framing was developed by StrataCom , Inc. in order to improve the efficiency of a pre-standard Asynchronous Transfer Mode (ATM) link protocol.
