The SS7 Signaling protocol ISUP (ISDN User Part): used to setup and release calls MAP (Mobile Application Part): used for signaling related to a number of services MTP1 MTP2 MTP3 SCCP TCAP MAP ISUP Call-related signaling No call-related signaling TCAP (TRANSACTION CAPABILITIES APPLICATION PART): provides the capability to exchange information between applications using non-circuit related signaling SCCP (SIGNALING CONNECTION CONTROL PART): realyze both connectionless and connection oriented network service and provides additional functions such as Global Title Translation MTP (MESSAGE TRANSFER PART): three levels corresponding to the OSI physical layer, data link layer and network layer. 25 maggio 2019 PISATEL

by providing a new level of abstraction JAIN Integrated Network APIs for the Java platform The objective of the JAIN initiative is to create an open value chain from 3rd-party service providers, facility-based service providers, telecom providers, and network equipment providers to telecom, consumer and computer equipment manufactures The JAIN initiative wants to integrate: wireline (PSTN), wireless (PLMN) and packet based (IP and ATM) networks by providing a new level of abstraction 25 maggio 2019 PISATEL

The JAIN initiative brings: Business Drivers and Industry Goals The JAIN initiative takes the telecommunications/Internet market from many proprietary closed systems to a single open environment able to host a large variety of services making next generation telecom application development faster, simpler and less expensive The JAIN initiative brings: Portability: Write Once Run Anywhere Network Convergence: Any network !!! Secure Network Access 25 maggio 2019 PISATEL
