3) Multi cluster network The figure shows a multi-cluster network, monitored and controlled by the PNMSj through LAN interface (IP network). Up to 192 remote clusters (up to 10,000 NEs) can be connected with PNMSj through LAN interface (IP network). The remote clusters are also possible to concentrate by using Management Interface Unit (MIU) and Hybrid Converter (HYB CONV) in the figure to the right.

Ring configuration is available only for the PASOLINK + /PASOLINK Mx. 5) Parallel PNMS configuration Two PNMSj can monitor and control PASOLINK network (up to 5,000 NEs) simultaneously and independently to provide fault redundancy function. They are connected through Router, as shown in the figure to the right. This configuration is called Parallel PNMSj. “Parallel" means that status change (ex. alarm and event occurrence) of each NE is recognized in both PNMS. Even if one PNMSj is down, the other PNMSj can monitor and control NEs in the network.

MTL-PL-020 Network Configurations 6) Hierarchical PNMSj Configuration Central and Regional PNMSj can be configured as shown in the figure to the right. Regional PNMSj monitors and controls PASOLINKs (up to 10,000 NEs) in its region. Central PNMS monitors and controls all PASOLINKs (up to 10,000 NEs) in all regions (up to 50 regions). It is considered an alternative configuration of “Parallel PNMSj “. Each NE is monitored and controlled by both Central and Regional PNMSj. It means that even if Central PNMSj is down, each Regional PNMSj can monitor and control NEs in its monitored and controlled region. In a similar way, if a regional PNMS is down, the central PNMSj can monitor and control NEs under the region where the regional PNMSj is down. (The logging data, performance monitor data and network configuration data are not synchronized between the central PNMSj and Regional PNMSj. Central PNMSj has some restriction of the function.) 7) Higher-level Management Interface In order to make NEC's PASOLINK family equipment an integral part of a higher-level management system, an optional SNMP interface to higher-level management system is provided with the PNMSj. The interface is based
