OTN Processor

The Gemini TPS5201MP OTN processors IP cores are a member of Tera-Pass’ product family for access applications. Gemini TPS5201MP processors support the functionality required by access networks and by premium services networks. Gemini TPS5201MP client ports support one or two Ethernet/SDH signals, provides EOS functionality, and conveys its payloads to an OTU1/OTU0 (2.7/1.3 Gbps) bearer. The OTU1/OTU0 signal may operate in a 1+1 protection configuration.

Gemini TPS5201MP IP Cores support 2 Ethernet FE/GE or SDH STM1/STM4 Client Ports and 2 OTN Line Ports. The SDH signals are monitored and then they are GMP mapped to ODU0 containers. For FE/GE, Gemini TPS5201MP generates the RMON statistics associated with each signal. Gemini TPS5201MP can map the FE/GE signals transparently (GMP/GFP-T) or GFP-F to ODU0 containers. Since in many applications there will be Ethernet switches implementing bandwidth limiting fronting it, the Gemini TPS5201 can map the FE/GE signals to multiple SDH VC4/VC3/VC12 component signals implementing a VCAT (Virtual Concatenation) capability. In case that the number of VC containers needs to be adjusted, Gemini TPS5201MP also provides an LCAS (Link Capacity Adjustment Scheme) capability. The resultant multiplicity of VC4/VC3/VC12 containers can be multiplexed to STM1 or STM4 signals. The ODU containers are then transported to their destination by OTU signals. Gemini TPS5201MP can multiplex 2 ODU0 containers to an ODU1 and transport the signals with an OTU1 bearer or transport a single ODU0 container over an OTU0 bearer.
