| TsLink3 Voice Supplementary Services SDK | Source Code Stack |
Voice Supplementary Services for Basic Rate (BRI), Primary Rate (PRI), and QSIG protocols expand the set of capabilities available with standard basic services. ETSI ISDN Supplementary Services are defined by the ITU-T Q.932 and ETS standards. North American ISDN Supplementary Services are defined by Telcordia, Lucent and Nortel specifications. QSIG Supplementary Services are defined by ECMA specifications.
The TsLink3 ISDN Supplementary Services/Q.932 Software Development Kit (SDK) source code modules are supplied in ANSI C source code software modules compliant with their respective specifications for PRI & BRI ISDN, and QSIG. Functionally, supplementary services translate requests and responses between ISDN terminal end points and Central Office (CO) or PBX switches in a standards-based form that that both switches understand.
Developers can accelerate project development and minimize technical risk by taking advantage of these proven Supplementary Service software modules. Usage of proven software modules enables a developer to focus on the actual applications without having to translate and direct the applications how to format the different Supplementary Services messages.
TsLink3 software SDKs are specifically architected for embedded and host-based applications where high performance and small code size are important.
Typical Applications:
- Multi-featured PBX/PABXs
- ISDN telephones
- ISDN terminals
- Gateways
- IADs
- Test equipment

TeleSoft Advantages
TsLink3 software stacks are specifically architected for all types of embedded and host-based applications and are optimized for excellent performance and small code size.
Written in ANSI C and delivered as source code SDKs ported to a defined RTOS of your choice, TsLink3 stacks give you an advanced starting point to shorten your development schedule, minimize technical risk and maintain the flexibility to exercise full control over your end product.
All TsLink3 protocol software stacks are based on a Standard Core Architecture (SCA) with a Universal API (UAPI) that enables easy migration between different stacks and portability to different software/hardware platforms.
Universal Application Programming Interface (UAPI)
TsLink3 code includes a rich message-based Universal API (UAPI) which presents a simple interface for simple applications such as "signaling-only." UAPI also provides the versatility and power needed to support more complex configurations which combine signaling with data protocols or with specialized hardware. The TsLink3 Universal API coupled with the straightforward structure of the TsLink3 protocol stack enables you to easily follow the API message flow through the code to determine where to make modifications required for your application.
The majority of simple signaling-only applications require a very small subset of the TsLink3 API messages and parameters - and the non-applicable messages can be disregarded and unused parameters set to zero. More complex applications benefit from the large set of messages and parameters that we provide as templates.
UAPI is common across all TeleSoft stacks which decreases the time and effort required to add upgrade modules to an existing TsLink3 stack and to develop with additional TeleSoft stacks.
Software Tools
Internal Protocol State Logging Tool and Debugging Tool are invaluable aids during portation and integration, included with every TsLink3 stack at no additional charge.

- ETSI/ECMA compliant code - ensures interoperation with other equipment (e.g., PBX) that is ETSI/ECMA compliant.
- ‘C’ switch statements that closely correspond to the ITU-T standard - straightforward to read and modify code, and locate the event/state action points in the ITU-T standard.
- Adherence to ANSI ‘C’ standards – provides for full portability.
- OS-independence - choice of RTOS, not locked into a single vendor.
- Processor-independence - enables mobility across CPU platforms.
- Simple state machine design - easy to understand and change code for national specific variants.
- Consult with our experienced engineers early to avoid expensive pitfalls later.
Faster debugging
- Specific defined constants, comment strings and variable naming - supports use of text search techniques to quickly locate a specific section of code and determine the side effects of changes that are being considered.
