Item Information
ESI IVX E-Class NSP-U 1-Port RJ-45 Network Services Processor Module


  • The NSP (Network Services Processor) serves as a bridge between an Ethernet-based network and the IVX E-Class system.
  • Using TCP/IP, the NSP communicates directly with specific PC applications for maintenance of, and integration with, the ESI phone system.
  • The NSP manages optional features such as VIP and phone control via TAPI PC applications; it also provides access to not only maintenance and administration (through use of Esi-Access and Esi-Admin) but also an Installer-selectable SMDR interface.
  • The NSP hardware interface consists of a dedicated Ethernet port. Its external RJ-45 jack provides a 10/100Base-T connection to the LAN. The NSP consumes no call-processing ports.
