Versatility
Providing solutions for the Next Generation Networks (NGN) in telephony, Deverto Systems Ltd. has developed the Tequet Soft Switch System (TSS). This is a flexible and modular system encompassing the following functional areas:
- Call switching control
- Presence engine
- PSTN integration
- Databases (number portability, line profile, provisioning, routing)
- Media resource functions including Interactive Voice Response (IVR) and Session Border Controller (SBC)
- Policy Decision Functions (PDF) for providing the appropriate QoS in the transport network
Target markets
The TSS is a universal platform, it is not conceived with only one market segment or technology solution in mind. The TSS has live implementations in the following market segments:
- Local Exchange Carriers (LEC) - incumbent or competitive
- Inter-exchange Carriers (IXC) - incumbent or challenger
- Mobile operators
- Internet Service Providers (ISP)
- Cable TV operators
- Internet Telephony Service Providers (ITSP)
- Academic and research networks
- Government networks
- Large enterprise networks
Pay as you grow
The licensing model of the solution is designed to fit the revenue stream of the operator. Initial investment is kept at the minimum, while cost growth is synchronized with the cash flow from operations in order to keep financing costs low.
Custom tailoring, time to market
There are no two identical customer networks. The TSS is an open development environment, meaning that rightsizing, custom tailoring can be done without developing and recompiling the code. This yields in a solution that can flexibly and quickly adapted to the needs of the particular deployment scenario. This flexibility turns in the shortened time-to-market cycles for not only saving money but acquiring a better market position for the customer.
To achieve this, the TSS has multiple programming languages for customizing its behavior. This includes ACL (Address Control Lists - a Deverto call control language), TCL (Tool Command Language) or Python.
There is a wide range of interfaces to connect to remote systems, databases. This includes e.g. SQL for relational databases, LDAP, ENUM, RADIUS, DIAMETER, MQSeries, CORBA, HTTP, SOAP, XML, etc. The TSS can be adapted to fit the pre-existing customer database schemata, there is no need to design backoffice systems from the ground up.
Best of both worlds
The TSS was designed with NGN in mind. There is no legacy "baggage" to carry. On the other hand, the system offers seamless and well integrated solutions to connect to traditional networks. The TSS has its own stack of PSTN signaling protocols e.g. SS7 call related and transaction capabilities (IN) and DSS1 (ISDN PRI/BRI).
As far as the new world protocols are concerned, the TSS supports all the three most widespread protocol families: H.323, SIP and MGCP.
There is a full signaling level interworking between all the supported protocols.
Scalability, carrier class availability
The system was designed according to the most advanced and state-of-the art industry practices. The system has a CORBA bus architecture with the different functional components (TSS modules) sitting on it.
With the components properly distributed, the system is scalable on four different levels: processor, node, cluster, network.
High availability is achieved by a clustering concept. The system is designed in a way that there is no single point of failure. Under normal conditions, the cluster nodes share the network load.
Cluster interconnection requires only plain TCP/IP, therefore, it is possible to spread the different components geographically. Catastrophe (or site) tolerance can, thus, be achieved. This means that full functionality is preserved even after a total loss of a site. Hardware and software maintenance is possible without service interruption. These high availability measures are proven in live deployments. |
