Low-cost CESoPSN solution and its G.8261 test
CESoPSN (Structured Simulation Protocol) plays an extremely important role in PTN and IPRAN systems. Through CESoPSN, PTN and IPRAN can be used for TDM services to achieve the integration and transition of 2G and 3G / 4G transmission networks.
SW2016F is a small-capacity CESoPSN chip solution based on the PWE3 international agreement. It has the features of complete functions, excellent indicators, and low cost. It fully complies with the test templates of the G.8261 standard. It is the comparison between PTN and IPRAN to implement E1 cards.优 计划。 Excellent program.
SW2016F is an FPGA solution. The mother chip uses XC6SLS16 with less than 10,000 logic units. It is a miracle for the simulation of the CESoPSN circuit of 16E1 with such a small mother chip. There is also an internal integrated LIU, and users can choose whether to use its internal LIU, so that the chip itself and peripheral costs are lower than those currently available in the market.

The index and stability are the most important for the CESoPSN chip, and in addition to the stability of the chip solution itself, its ability to adapt to the network is an important manifestation of its stability. Specifically, the chip is mainly reflected in the adaptation data The capability and indicators of jitter (PDV) included in the packet network are currently required by G.8261 in detail. At the same time, the requirements of G.8261 are also required by China Mobile ’s recent bidding based on the experience of using PTN network. SW2016F is currently The only chip solution known in the market that has passed the G.8261 template, and it has the test and real engineering significance because it does not need to change the code and make any settings when it passes different G.8261 templates. Below is the network business flow model 2 The test screenshots of test template 1 and template 2 are attached. The reason for attaching these two screenshots is that template 1 and template 2 are currently the most difficult to pass at the same time in the industry. Chengdu Long Ruixin is also based on PDV and its algorithm. Only after years of research and accumulation did they take the lead in realizing:
