TsLink3 Multi-Link 3 Frame Relay Features

• Supports provide Multi-link and Fragmentation services: 
  • Fragmentation services allow real-time and non-real-time data to co-exist on Frame Relay links.  
  • Multi-link services allow aggregating the bandwidth of several links into one virtual link,  
  • Fragmentation may be enabled End-to-End, UNI/NNI, or both.  
  • Multi-link may be enabled End-to-End, UNI/NNI, or both.
  • Fragment size set by configurable constants.
  • Both services may be used in ISDN or non-ISDN environments.  
• Services are individually enabled to allow use in a mixed interface environment .
  • Permanent Virtual Circuits (PBCs) and Switched Virtual Circuits (SVCs) per FRF4
  • DTE (User) Side + DCE (Network) Side (PVC only)
  • Dynamic run-time configuration with Forum Local Management Interface (LMI)
  • Network Management Interfaces conform with ITU-T Primitive Interfaces
  • Q.933 Annex A and T1.617 Annex D PVC
  • Modular structure easy to customize using defined constants.
  • Higher-layer independence allows transparent transport of other protocols, including;
  • TCP/IP, SNA, X.25/X.75 & ISDN.
  • Supports testing both sides of the network.
  • Layer 2 DL-CORE Module
  • DTE & DCE Side implementation of Data Link - CORE and LMI functions
  • Functions supported include: 
    • Congestion Control and Explicit Congestion Notification (ECN) 
    • Data Link Connection ID (DLCI), up to 922 users 
    • Multicast-configurable to network needs 
    • Discard Eligibility bit 
    • Heartbeat Process to verify physical link integrity  
  • 1024 PVC DLCIs for support of up to 255 active connections

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.
