1 Squire Technologies SVI_STP Signal Transfer Point Date, Audience details
SVI_STP Overview The SVI_STP provides a comprehensive and flexible SS7 STP solution for transporting SS7 signalling over traditional TDM based networks and next generation IP based networks. 2 The SVI_STP s support for any-to-any interworking between traditional and next generation networks allows both fixed line and mobile networks to take advantage of the cost saving and next generation service offerings of IP networks
Benefits Cost Saving Deploying the SVI-STP allows operators to take control of their SS7 Networks by consolidating traffic and providing local routing reducing SS7 interconnect and infrastructure costs The SVI-STP allows operators to create private SS7 networks issuing their own Virtual Point Codes instead of purchasing expensive SS7 Point Codes from incumbent carriers. This also facilitates rapid network deployment and expansion. 3 Revenue Generating Deployment of the SVI-STP allows operators to deploy their own LNP and CNAM services. This provides immediate cost benefits as operators no longer need to purchase these services from 3rd party providers and also allows operators to deploy their own revenue generating LNP/CNAM services to other operators.
Benefits Future Proofing Full support for next generation IP based networks allowing operators to take advantage of the inherent costs savings and next generation services provided over IP networks while maintaining and bridging to incumbent TDM networks 4 Scalable The SVI-STP can be scaled from an entry level deployment to large scale with modular license and hardware upgrades to match the exact growth requirements of the operator.

CNAM/ LNP Revenue Generation LNP/ CNAM DB Provider TCAP send TCAP receive Switch IAM IAM/ TCAP Pre-dipped Carrier 10 With a centralized STP controlling the signaling, inline dipping of AIN services enables previously unsupported switches to access CNAM and LNP dips directly from the providers network at significantly reduced rates. Managing a single SS7 interconnect enables the provision of inline dipping with obvious cost savings as well accelerating future network development.

Gateway Screening Provides operators the ability to examine all incoming and outgoing messages against pre-defined rules. The end result is that either a message is routed or discarded. Gateway Screening is performed on the following MSU parameters MTP 3 Screening Calling Party ISUP Service Indicator Encoding Scheme ISUP message type Affected PC in management messages Originating Point Code Destination Point Code Global Title Indicator Nature of address indicator Numbering Plan Point Code General Screening Byte pattern and offset 12 SCCP Screening Called Party Encoding Scheme Subsystem number Translation type Global Title Indicator Nature of address indicator Numbering Plan Point Code SCCP management screening Affected Point Code Affected subsystem number Subsystem number Translation type
