PTN equipment is an optical transmission equipment used in the access layer and aggregation layer to replace SDH. Its function is to transmit voice services and data services in fixed network and mobile backhaul. Its biggest feature is It makes up for the rigidity defect of SDH time slot circuit by realizing the statistical multiplexing function.
The future transmission network will be PTN OTN networking, and will no longer be the current SHD DWDM networking method.
PTN: (English full name: PacketTransportNetwork) means packet transport network. Its functions are:
1. It can well solve the problem of TDM in the context of the evolution of mobile networks from 2G to 3G. The gradual transition of services to IP services to meet the unified access and transmission of 2G/3G base station backhaul services is an important development direction of the next generation metro transport network.
2. The packet transmission network is located between the physical layer of the first layer and the IP layer of the third layer in the vertical network protocol. It can provide efficient statistical multiplexing transmission for packet services. The network structure supports hierarchical domain division. It has good scalability;
3. It can provide reliable network protection and OAM management functions, has complete QoS functions, is compatible with the integrated transport network technology of traditional TDM, ATM, FR and other services, and supports packet Time and clock synchronization;
4. The packet transmission network needs to have multiple functions to realize the transmission of the above services, including the inherited functional requirements of the original SDH transmission network and new functional requirements.
