SSPAn access point for IN servicesSSP identifies the IN call by
analysing the Service KeyInitiates a query to SCPResumes to further
call processing after receiving the advice from SCPSSP to SCP
interface is G703 digital trunkProtocols supported MTP,SCCP,TCAP
and INAPSCPStores data conerning Network, services logic and
customersMost important database hence fault tolerantService
programs and data are updated from SMPCommunicating to SSP and
IPSMPFront end of SCP and provides the user interfaceUpdates SCP
with new data and service logics and collects statistics from
itService provider is connected with X25 connection or IPContain
the service creation environment of new services
INProvides enhanced services to all SSPs in an IN under the
control of SCPA centralised service for sharing purposeThe main
resources are1.IVR2.Announcements3.Voice mail boxes4.Speech
Recognition system5.Text to speech convertersInterfaces to SSP via
ISDN PRI or G703Protocols supported ISUP,INAP,TCAP,SCCP and MTP
