Network surveillance

Extended network processor (NPx)

The NPx supports TCP/IP, X.25, and a seven-layer OSI stack. The NPx communicates with Site Manager and the Multiservice Managed Object Agent (MOA) over TCP/IP. It supports TL1 communication over X.25 with other operations support systems (OSS). The NPx communicates with the co-located extended shelf processor (SPx) through the backplane over Ethernet. The NPx also allows up to 16 nodes with network processors or ILAN cards to be daisy-chained through the intershelf local area network (ILAN).

The NPx supports three user accounts with a level 5 UPC for network surveillance purposes. Each level 5 user has visibility to NPx’s span of control of up to 16 network elements. Logging in to the NPx using a user account with a level 5 UPC from a local connection, you can retrieve alarms and events from all network elements in the network processor span of control. The NPx can have up to 16 network elements in its span of control.

The NPx supports file transfer to and from Preside and Multiservice MOA for electronic software delivery, and to and from a PC to install files on the system. The NPx also allows other network processors or shelf processors to retrieve new software loads for upgrade purposes.
