Telesoft Technologies’ TDAPI SIGTRAN is a software-based protocol stack providing SS7-based signaling protocols over next-generation
IP networks.
With the growing diversity of networks it is important for equipment manufacturers to provide, and operators to have, solutions that allow them to connect to other external networks and at the same time meet certain performance criteria, i.e. availability and throughput. Telesoft Technologies’ signaling capability and solutions are key elements in achieving this and in providing reliable and flexible functionality.
SIGTRAN is a suite of protocols used to transport real-time signaling, e.g. SS7 (signaling system 7), over IP networks using SCTP (stream control transmission protocol). The SIGTRAN stack is controlled by the IETF which has produced a number of RFC guidelines (inc RFC2719) which allow SS7 to be successfully used in IP environments.
Telesoft Technologies’ high-performance TDAPI SIGTRAN stacks allow users to port signaling applications, built for SS7 networks, to IP with minimum effort. The SIGTRAN stack supports the same layer 4 protocol stacks and APIs as the MPAC Telephony Boards, allowing simple re-configuration of existing applications. Higher level protocols supported include ISUP, BICC, IUP, SCCP, TCAP, MAP, SMS, CAMEL, IS-41, WIN, M3UA and SCTP.
TDAPI SIGTRAN is a software-based solution that runs on standard servers and requires no specialized hardware.
New TDAPI users will find the SIGTRAN API easy to use and ideal for rapid application development. The SIGTRAN stack is based on M3UA, the most commonly used adaption layer, and can be configured to work in application server mode, in signaling gateway mode, or IP signaling point (IPSP) mode.
The SIGTRAN stack optionally includes the C-CURE API providing telco grade reliability for high availability systems. The C-CURE API may be deployed in either load-share or worker-standby configurations to provide 99.999% operational reliability by eliminating single points of failure and avoiding service downtime.
