OTN Processor
The Zephyr TPS6201MP OTN processor IP cores are a member of Tera-Pass’ product family of OTN access components. Zephyr TPS6201MP supports general access applications and Premium Services networks for the transport of 8 client signals over an OTU2 line side link. The 8 client signals can be 6 FE/GE and 2 FE/GE/STM1/STM4 signals. Zephyr TPS6201MP incorporates an integrated EOS functionality. The OTU2 line side may operate in a 1+1 configuration.
Zephyr TPS6201MP IP Core processors can accept 8 Client Signals. 2 of the Client Signals can be FE/GE/STM1/STM4 and 6 Client Ports can accept FE/GE signals. FE/GE signals are first processed to generate their corresponding RMON statistics. Afterwards, the FE/GE signals can be transparently (GFP-T for GE and GMP for FE) or GFP-F mapped to ODU0 containers. In cases where Ethernet switches fronting the Zephyr TPS6201MP implement bandwidth limiting functionality, the FE/GE signals can also be mapped into multiple SDH containers (EOS, Ethernet Over SDH). The mapping of the FE/GE signals to SDH is done using a GFP-F procedure and a VCAT mechanism that makes use of VC-n-Xv containers. The component signals can be VC4/VC3/VC12. An LCAS mechanism can be used if there is a need for a subsequent change in the number of VC containers. The STM1/STM4 SDH signals are processed to generate their respective Performance Monitoring data and Alarms and are GMP mapped into ODU0 containers. The ODU0 containers, transporting either Ethernet FE/GE or SDH STM1/STM4 payloads, are then multiplexed into an ODU2 container that is transported over an OTU2 signal. The 2 Line Ports can be configured to operate in a 1+1 facility protection mode.
