OSN1500 SNCPW protects the service by selecting and receiving the two service sources that are double-entered from the source at the host side, so double-entry selective receiving is a feature of SNCP.SNCP protects the service by double-entering the service at the source side and selecting and receiving the two services that are double-entered at the host side.With the double-entry selective-receiving feature, SNCP is applicable to the protection of the cross-subnet service. SNCP has the function of double transmission and reception selection, which is suitable for protecting cross-subnet services. When SDH services are configured in the single-site mode, SNCP can be created to realize the protection of cross-subnet services when they need to be protected, and SNCP has the function of selecting and receiving for double transmission, which is applicable to the protection of cross-subnet services. The most important feature of the service is that it adopts a dedicated physical channel as the protection channel and the service is dual transmit and receive. When configuring SNCP services, you need to configure the working service and the protection service separately.
