How’s the Hybrid Networking with the RTN Equipment
The OptiX OSN 3500 supports hybrid networking with the RTN equipment, therefore implementing end-to-end management.
As shown in Figure 1, hybrid networking allows more flexible reform of the existing network and optimal utilization of the network resources.
In the preceding typical networking, the OptiX OSN 1500 or OptiX RTN equipment is used at the access layer.
The OptiX OSN 3500/7500 is often used at the convergence/backbone layer.
See Figure 1. In packet domain, the equipment at the access layer, such as the OptiX OSN 1500 or the OptiX RTN equipment, accesses the FE services from the NodeB, and transmits the FE services to the GE packet ring, then to the 10GE convergence/backbone ring, and finally to the RNC. In this manner, the FE services from the base stations are transmitted to the RNC in an end-to-end manner.
See Figure 1. In TDM domain, the equipment at the access layer, such as the OptiX OSN 1500 accesses the E1 services from the BTS to the STM-1/STM-4 ring consisting of the MSTP equipment and then transmits the service to the STM-16/STM-64 ring consisting of the OptiX OSN equipment (convergence/backbone layer) and finally to the BSC. In this manner, the E1 services from the BTS are transmitted to the BSC in an end-to-end manner.
In the hybrid networking of the OptiX OSN 3500, the MSTP equipment, and the RTN equipment, a unified NMS is used.
