svi tas headerTelephony Application Server

The Telephony Application Server (SVI_TAS) enables the rapid delivery of converged services across IMS, NGN and Legacy SS7 networks. The SVI_TAS enables operators to leverage existing infrastructure, extend return-on-investment and rapidly deploy new services.

Rapidly devise, test and deploy services. Whether you are looking to interwork DIAMETER or SIP with legacy SS7 CAMEL/INAP/MAP, or you are looking to interface a new subscriber database over SQL/SOAP/HTTP into your incumbent networks the SVI_TAS will:

  • LEVERAGE existing IMS, NGN and legacy infrastructure
  • MITIGATE against vendor lock-in and product end-of-life
  • RAPIDLY deliver custom services across disparate networks

Overview

tas api network

 

tas apiThe SVI_TAS operates over clearly defined API's that present an abstracted version of the underlying DIAMETER, SIP, CAMEL, MAP etc signalling. It can be driven by either Squire Technologies python based client (SVI_TAC) or by operators 3rd party applications, and provides an extremly flexible, service driven platform with huge benefits:

Deliver only those services that you require instead of paying for a full application suite that you will never use

 

tas powerful iconPowerful
Services built using industry standard Python scripting language

 

tas scalability iconExtendable
Extend services using in-house resources or let our experts develop at a fixed cost

IM-SSF

The SVI-TAS supports the 3GPP IMS component the IM-Service Switch Function (IM-SSF) 3GPP 23.278 providing a seamless bridge between an IMS network (SIP) and a CAMEL based SS7 Intelligent Network.

When an operator initially deploys an IMS network they are unlikely to be able to enable all the revenue services available to their existing legacy subscribers. To insure continuity of service the IMS network can leverage the existing Intelligent Network through the IM-SSF component.

Reverse IM-SSF

In “reverse” the IM-SSF allows legacy subscribers to access the new services available in an IMS network. It is the glue that allows legacy subscribers to access new services run from SIP application servers – i.e Mobile PBX, OTT etc.
