Harris Network Swtiching Center

IP-based Switching and Management

The Harris NSC manages the routing of voice and data to mobile subscribers with commercial off-the-shelf equipment and includes an optional high-availability configuration.


NSC Components1

  • The NSC is comprised of a Network Switching Server (NSS), Standard LAN/Wan networking equipment, an Interoperability Gateway and a level of network management dependant on the number of NSC within the network.
  • The Network Switching Server (NSS)routes calls to and from each voice group or mobile data user on a real-time basis.
  • An Interoperability Gateway which provides connection points to analog devices, can be centrally located with the NSC equipment.

Network Management

  • Each NSC in a network is managed by the Regional VIDA Manager (RVM) which is composed of two software applications: the Regional Network Manager (RNM) and the Unified Administration Server (UAS). The RNM provides management support for the various hardware and software components that make up the network and the UAS provides the capability to define and structure the systems, sites, talkgroups, users and other resources.
  • When a network contains more than one NSC, each RVM is connected to a centralized administration point, the Centralized Network Manager (CNM). The CNM isthe consolidated point for viewing and monitoring the performance of the entire network.
