TeleSoft licenses TsLink3 device drivers for use with TsLink3 telecom and datacom protocol stacks designed for developers. Low-level drivers for many different chips are available. Protocol stacks include ML-PPP, PPP, X.25, Frame Relay, T1 RBS, E1 CAS R2, ISDN, QSIG, AO/DI and DSL.

Manufacturers license TsLink3 conformance-proven source code stacks to get their products to market faster while minimizing technical risk and development costs.

"TeleSoft code made our ISDN product feasible; it saved us at least one year of market opportunity." --  NxNetworks/Proteon, Westborough MA

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.

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.

Purchasing TsLink3 Software
TsLink3 Source Code is supplied in comprehensive, portable packages of 'C' 
source code modules and interfaces necessary to develop robust products. 

Source Code packages provide source code from Layer 1 device driver software up through the Layer 3/Layer 4 interface of the OSI model. 

Upgrade and Individual Modules
Completing the solution are upgrade- and individual-modules that increase your market opportunity by increasing your products' connectivity capabilities. Modules include PPP, ML-PPP, X.25, AO/DI, Frame Relay, T1 RBS, E1 CAS, R2, V.120, and Supplementary Services.
