TsLink3® T1/E1 Signaling Protocol Source Code from TeleSoft International

URL: http://www.telesoft-intl.com

The T1/E1 Signaling protocol stack from TeleSoft is ANSI C source code that is used by developers of communication products. TeleSoft's software packages are designed to greatly reduce development time and easily integrate into the target platform.


Company Information
TeleSoft International, Inc.: TeleSoft specializes in the development of Source Code Protocols. TeleSoft supplies SS7, V5.x, H.323, ISDN, QSIG, Frame Relay, T1 & E1 CAS and X.25 Protocol Stacks for license to manufacturers of communications products.

T1 Robbed Bit and E1 Channel Associated Signaling are digital protocols used in the generation and detection of the tones used to set up and tear down channels on T1 and E1 links.

The TsLink3® T1/E1 Signaling protocol stack supports the following:

T1 Robbed Bit Features
• Three T1 robbed-bit signaling variants, each use ABCD signaling
- EIA-464B/AT&T TR41458 E&M Wink start
- EIA-464B FXS Ground start
- EIA-464B FXS Loop start
• Direct Inward Dialing (DID) support (wink start)
• Simple ABCD bit poll/set interface
• DTMF Tone Processing module

E1 CAS (R2) Features
• Supports ITU-T standards Q.400-Q.480 via:
- Line signaling call setup state machine for ABCD bit-handling
- R2 signaling state machine for MF tone handling
• Simple ABCD bit poll/set interface
• MF Tone Processing module for R2 protocol
• MF Tone Generation Simulator

Major operating systems are supported with pre-ported interface modules.

TeleSoft specializes in the development of Source Code Protocols for license to manufacturers of communications products. Products include SS7, V5.x, H.323, ISDN, QSIG, Frame Relay, T1 & E1 CAS and X.25 Protocol Stacks

TeleSoft gets customers to market quickly with well written proven ANSI C source code, comprehensive documentation and responsive expert technical support. The TeleSoft Protocol Stacks can be adapted quickly to any design by using pre-ported modules for common CPU's including AMD's E86™ Embedded Processors, Layer 1 physical devices and embedded operating systems.
