Voice Supplementary Services/Q.932 Source Code For QSIG, PRI & BRI ISDN translates requests and responses so that the switch understands them, enabling you to write your application without directing it how to format the Supplementary Services messages. Primary Rate (PRI) Supplementary Services drivers, protocol stacks, and source code libraries accelerate development and conformance testing of ISDN-enabled products.
Voice Supplementary Services is architected for embedded and host-based applications in which performance and code size are important.
For:
- Multi-featured PBXs
- Gateways
- Test equipment
"TeleSoft has always been a great partner helping us to integrate the ISDN stack into our application. Their code and support is superior. That's what sets them apart." -- Voyant Technologies, Westminster CO
Well-Structured, Maintainable Code
Maintainability and scalability are designed into each Voice Supplementary Services stack. Comprehensive comments and documentation support you or a colleague as your product goes forward. The value of Voice Supplementary Services stacks will be evident in each phase of your engineering schedule and the product life span.
Shorter Learning Curve & Faster Customization
- ITU-T primitives and software structure -> Easy to relate Voice Supplementary Services code to other ITU-T based protocols (e.g., E1 CAS, X.25, FR).
- '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 -> full portability.
- OS-independence -> Choice of RTOS, not locked into a single vendor.
- Processor-independence -> Mobility across CPU platforms.
- Simple state machine design -> easy to understand and change code for national-specific variants
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.
- ITU-T primitives and software structure -> Clear traceable dataflow.
- Development and testing on Voice Supplementary Services hardware -> Clean, proven "rock solid" code.
Smaller Inventory
- Each line can be configured at run-time for a different T1, E1, R2, PRI or BRI variant
- Co-resident T1, E1, R2, ISDN PRI and BRI switch variants, Frame Relay, X.25, PPP, and ML-PPP stacks.

Special Features and Upgrade Modules
Universal Application Programming Interface (UAPI)
Voice Supplementary Services 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 Voice Supplementary Services Universal API coupled with the straightforward structure of the Voice Supplementary Services 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 Voice Supplementary Services 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 Voice Supplementary Services stack and to develop with additional TeleSoft stacks.
High Availability (HA)
Voice Supplementary Services supports High Availability applications for high density switches with multiple modes of HA operation, including the seven key elements of HA. Please refer to the
TeleSoft HA White Paper
for details. Applications requiring HA will benefit from the Voice Supplementary Services stack capacity to support up to 64,000 simultaneous connections and up to 256 ports.
Software Tools
Internal Protocol State Logging Tool and Debugging Tool are invaluable aids during portation and integration, included with every Voice Supplementary Services stack at no additional charge.
