TsLink3 is architected for embedded and host-based applications in which performance and code size are important.
For:
- PABXs
- Digital loop carrier systems
- Network interface cards
- Switches
- Terminal adapters
- Test equipment
"TeleSoft solutions were an excellent value. They cut our development expenses by 2/3rds." --
Patriot Scientific, Poway CA
 Maintainability and scalability are designed into each TsLink3 stack. Comprehensive comments and documentation support you or a colleague as your product goes forward. The value of TsLink3 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 TsLink3 code to other ITU-T based protocols (e.g., E1 CAS, X.25, FR).
- State machine organizes and formalizes the ABCD bit protocol.
- '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 TsLink3 hardware -> Clean, proven "rock solid" code.
Smaller Code Inventory Required
- 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)
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.
High Availability (HA)
TsLink3 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 TsLink3 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 TsLink3 stack at no additional charge.
