TsLink3 ML-PPP/PPP source code is among the telecom and datacom protocol stacks that TeleSoft International licenses to developers. Manufacturers license TsLink3 ML-PPP source code, PPP source code and other TsLink3 conformance-proven source code stacks to accelerate the development and conformance testing of in-band signaling products.

TsLink3 signaling protocol source code is architected for applications, both embedded and host-based, in which performance and code size are important.

For:

Base stations
Gateways
Network interface cards
Switches
Terminal adapters
Test equipment

"We appreciated TeleSoft's code flexibility and the reliability of the technical support. TeleSoft technical support ensures that customers can successfully integrate and adapt TsLink3 code for their own platform." -- Digicom, Italy

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

Consistent use of IETF RFC state mechanisms -> Clear, traceable protocol handshakes.
'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

Development and testing on TsLink3 hardware -> Clean, proven "rock solid" code.

Smaller Code Inventory Required

Co-resident T1, E1, R2, ISDN PRI and BRI switch variants, Frame Relay, X.25, PPP, and ML-PPP stacks.

RFC Descriptions

RFC 1990, ML-PPP over 'n' ISDN B-Channels enables bundling of ISDN links to increase the number of B-channels available for aggregation, increasing the bandwidth supported for a single data session
RFC 2125, Bandwidth Allocation Control Protocol (BACP)- an industry-standard method to manage the dynamic bandwidth allocation in a multi-link bundle. Used in response to changing line or resource conditions between two peers to coordinate the addition and removal of individual links.
RFC2684, Multiprotocol Encapsulation over ATM LLC/SNAP- two encapsulation methods for carrying network interconnect traffic over AAL type 5 over ATM. The first method allows multiplexing of multiple protocols over a single ATM virtual connection whereas the second method assumes that each protocol is carried over a separate ATM virtual connection.
RFC2516, Point-to-Point Protocol over Ethernet PPPoE- provides the ability to connect a network of hosts over a simple bridging access device to a remote Access Concentrator by encapsulating PPP packets over Ethernet.
RFC2364, Point-to-Point Protocol over ATM PPPoA-provides the ability to establish a point-to-point relationship between peers using ATM Adaptation Layer 5 (AAL5) for framing PPP encapsulated packets.
RFC2153, Point-to-Point Protocol-provides a standard method for transporting multi-protocol datagrams over point-to-point links. PPP defines an extensible Link Control Protocol (LCP) for establishing, configuring, and testing the data-link connection; and a family of Network Control Protocols (NCPs) for establishing and configuring different network-layer protocols.
RFC1994, Challenge Handshake Authentication Protocol (CHAP)- the next best password scheme over PAP-a three-way handshake using a public domain encryption algorithm to securely pass user information across the link to authenticate a user with the server.
RFC1334, Password Authentication Protocol (PAP)-the basic internet password scheme-sends the user name and password in the clear to the server.
RFC1962, PPP Compression Control - provides the framework to link in a compression software package, such as STAC, for higher throughput on PPP links.
RFC 1662, Async-PPP to Sync ML-PPP converter allows PC based asynchronous PPP implementations (COM port-based products) to communicate with synchronous PPP based routers or bridges via ISDN terminal adapters
RFC1638, Bridging over PPP -allows digital products to send any LAN protocol over the link; required for LAN-LAN communication without IP.
RFC 1332, IP (both static and dynamic) over PPP allows ISDN products to send Internet Protocol (IP) over an ISDN link; required for communications with Internet-connected routers

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.
