The NOAM component consists of one active NOAM and one standby NOAM server running in a high availability configuration. It accepts subscriber data provisioned by the customer over PDBI and replicates it to the DR NOAM, the Query Server and all subtending SOAMs. It also provides a GUI which is used for configuration, user administration and the viewing of alarms and measurements.
NOAM distributes all successful incoming subscriber provisioning data, independent of source, to all downstream Network Elements and the DR NOAM at a rate of up to 200 provisioning database updates per second. In order to ensure the database levels of the Network Elements are less than the database levels of the NOAM and DR NOAM, the active provisioning site NOAM provisions the DR NOAM prior to updating the Network Elements.
The DR NOAM is a geographically independent NOAM component. The DR NOAM has the same hardware configuration and network accessibility as the NOAM.
The DR NOAM's databases are kept up to date through real-time replication of subscriber and application data from the Active NOAM. Under normal operating conditions, the DR NOAM does not provision any downstream systems but if made Active, it will take over all the functions of the Active NOAM including the PDBI and database replication to subtending SOAMs.
The SOAM component consists of one active SOAM and a standby SOAM server running in a high availability configuration. It accepts subscriber data replicated from the Active NOAM and in turn replicates it to all subtending MPs located in the same physical frame. SOAM also provides a GUI used for local Signaling configuration and viewing alarms and measurements details specific to components located within the frame (SOAM, MP).
The SOAM supports up to 10 MPs.
The Query Server is an independent application server containing a replicated version of the PDBI database. It accepts replicated subscriber data from the NOAM and stores it in a customer accessible MySQL database. A Query Server is located in the same physical frame as each NOAM component (NOAM / DR NOAM).
The system can support two NOAM Network Elements and up to 40 Signaling Network Elements.
The MPs are servers with the HLR Router application installed that are configured for MP functionality. They accept replicated subscriber data from the local SOAM and store it in a subscriber database.
The MP is accessed as a Service Relay Point and is connected to the Eagle STPs via Sigtran M3UA interfaces. Each MP is capable of relaying real-time SCCP messages at a maximum sustained rate of 25,000 transactions per second for HLR routing lookups. Multiple MP servers may be deployed in a single frame in order to scale query capacity. Each site can support up to 10 MPs, but the HLR Router System can support up to a total of 96 MPs in the system.
