SDH transmission equipment_OptiX PTN960 can be placed on the base station side for base station service access, or in the aggregation node as a service aggregation device, which integrates the services accessed by multiple OptiX PTN910s and transmits them to higher-level devices.The typical network of OptiX PTN960 is shown in Figure 1-2.OptiX PTN960 accesses services from the base station side through E1, FE or GE, and uses FE or 10GE interfaces for networking among PTN devices. or GE to access services from the base station side, and FE, GE, or 10GE interfaces are used to organize the network between PTN devices. OptiX PTN 3900/3900-8 on the BSC (Base Station
Controller)/RNC (Radio Network Controller) side connects to the BSC/RNC after service aggregation.
