INAP can be considered as the logic which controls telecommunication services which have been migrated from traditional service switching points (SSP) toward newer computer-based service platforms.

Techopedia Explains Intelligent Network Application Part

The intelligent network application part serves as the signaling protocol between service switching points, service control point (SCP) and intelligent peripherals or network media resources.

The service control unit consists of logic programs and data from third-party derived services or operators.

INAP is the protocol in use for intelligent network communication in most places outside of North America. It is based on published International Telecommunications Union capability sets (CS).

Applications use INAP protocol in order to perform remote operations between network nodes, for example between SSP and SCP.

INAP then deliver these remote operations encapsulated within the TCAP component sublayer towards peer application processes in a remote node.

Services defined by INAP:

  • VPN short digit extension dialing service

  • Single number service

  • Do not disturb service (call forward)

  • Personal access service (user management of calls)

  • Disaster recovery service (backup call destinations)
