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.
EoPoS is a standardized method for transporting native Ethernet frames over a SONET/SDH network, by first mapping into one or more PDH tributaries such as T1, E1, or DS3. The tributaries can then be dropped from a legacy ADM , delivered to the customer premises, and the PDH links resolved back to an Ethernet connection by a piece of equipment ...
After traversing SDH paths, the traffic is processed in the reverse fashion: virtual concatenation path processing to recreate the original synchronous byte stream, followed by decapsulation to converting the synchronous data stream to an asynchronous stream of Ethernet frames. The SDH paths may be VC-4, VC-3, VC-12 or VC-11 paths.
SDH has been mainly managed using the Q3 interface protocol suite defined in ITU recommendations Q.811 and Q.812. With the convergence of SONET and SDH on switching matrix and network elements architecture, newer implementations have also offered TL1. [21] Most SONET NEs have a limited number of management interfaces defined: TL1 Electrical ...
OTN was designed to provide higher throughput (currently 400G) than its predecessor SONET/SDH, which stops at 40 Gbit/s, per channel. ITU-T Recommendation G.709 is commonly called Optical Transport Network (OTN) (also called digital wrapper technology or optical channel wrapper ).
In telecommunications, subnetwork connection protection (SNCP), is a type of protection mechanism associated with synchronous optical networks such as synchronous digital hierarchy (SDH). SNCP is a dedicated (1+1) protection mechanism for SDH network spans which may be deployed in ring, point to point or mesh topologies .
The .500 Jeffery (12.7x70mmRB) is a big-game rifle cartridge that first appeared around 1920, and was originally introduced by the August Schuler Company, a German firm, under the European designation "12.7×70mm Schuler" or ".500 Schuler".
The WAN PHY was designed to interoperate with OC-192/STM-64 SDH/SONET equipment using a light-weight SDH/SONET frame running at 9.953 Gbit/s. The WAN PHY operates at a slightly slower data-rate than the local area network (LAN) PHY. The WAN PHY can drive maximum link distances up to 80 km depending on the fiber standard employed.
