QSIG-ISDN-CAS R2 RBS Gateway Software -- "C" Source Code

QSIG-PSTN-CAS R2 RBS Software for Signaling Interworking

TeleSoft International provides QSIG-PSTN signaling interlocking, which includes TeleSoft's ISDN protocol stack, T1 RBS  E1 R2 CAS protocol stack, and QSIG protocol stack in order to accelerate development and interoperability testing of your gateway or similar product. TeleSoft's QSIG and ISDN protocol stacks provides the fastest path to market-ready ISDN products for manufacturers worldwide.

TsGATE is an integrated software QSIG to PSTN Gateway software design kit that translates the signaling messages on SIP networks to the  messages used on the digital PSTN networks. TsGATE takes advantage of existing proven TeleSoft stacks by combining the TsLink3 QSIG stack with the TsLink3 PSTN signaling stacks and integrating these with the TeleSoft QSIG-PSTN Interworking Module. TsGATE is an ideal solution for OEMs developing embedded gateways and adapters since the TsGATE Soft Gateway is hardware and RTOS independent and can be ported to a wide variety of platforms to create Private to Public network signaling conversion products.

The TsLink3 ISDN, QSIG and CAS RBS R2 stacks all support the TsLink3 API, and for those who have a need for a flexible and powerful interface, the TsLink3 API is a great choice.  TsGATE offers a library of code that you would otherwise have to write yourself if you are building a protocol converter, transit (class 4) switch, CO (class 5) switch, PBX, or similar device.  TsGATE is supplied in C source code, and you can customize it as you desire.

QSIG-PSTN Signaling Interworking Features

QSIG-PSTN Signaling Interworking applications

TsGATE Soft Gateway is ideal for for cost and memory sensitive applications, from a desktop terminal adapter to the largest system. 

Small Gateway QSIG-PSTN applications:

The small RAM and ROM footprint of TeleSoft's software development toolkits means that you can save memory.  And the fast execution speed allows use of a slower processor;  fewer instruction cycles means that the processor can "sleep" more thereby lowering power requirements. 

These devices may route calls from an office's telephones to a private network, while routing selected calls to the public switched network.

Large Gateway SIP-PSTN applications:

The low per-call memory requirement of TeleSoft's SDKs means that you can save a significant amount of memory when your gateway services thousands and tens of thousands of calls.  And the fast execution time results in more calls per MIPS, or in lower power requirements for a given number of calls.  This translates into lower power requirements for your system, less heat generated by the processor, lower air conditioning requirements--in short, better NEBS performance.

These devices may enable a standard PBX to connect to both public and private networks,

QSIG - ISDN Gateway Signaling Interworking Digaram

TeleSoft International is a premier supplier of circuit switched telephony and VoIP Protocol signaling stacks & solutions to leading OEMs worldwide. TeleSoft has been selected by more than 250 OEM customers and we continue to provide robust, mature, conformance and interoperability tested solutions to customers who require the best performing software stack solutions.

The TeleSoft protocol software development toolkits (SDKs) offer highly optimized protocol stack solutions that combines very small memory footprints with high performance and no compromises on functionality and scalability. All TeleSoft SDKs are supplied in source code written in ‘C’ for ease of portation.

Telecom and VoIP have needs that are different than data communications, and the industry is just realizing how different VoIP is from datacom.   Telecom protocols are required to be robust, and if VoIP is to be widely accepted, it must be as robust as the existing PSTN.  Doesn't it make sense to license your Voice over IP (VoIP) signaling protocol from the voice experts?

TeleSoft International is the original developer of the TsLink3 range of high performance WAN protocols including SIP, ISDN BRI and PRI, QSIG, CAS E1 R2, T1 RBS, AO/DI, ML-PPP, Frame Relay, X.25, and also a range of hardware reference designs. TsLink3 protocol source code is exceedingly well engineered - tightly coded for performance and compact footprint, with a quality that delivers rock-solid stability.

TeleSoft's foundations go back to 1986 when the first ISDN stack was released. Since then TeleSoft's protocols have been proven in use by more than 200 customers worldwide. World leaders, including AT&T, Cisco, D-Link, Digital Equipment, Fujitsu, IBM, Lucent, Matsushita, Multi-Tech, NTT, Polycom, and Vertical Networks have all used the source code for  TeleSoft's proven protocol software.

Manufacturers license the source code for TeleSoft's proven Protocol Stacks and Reference Designs to get their products to market faster with minimized technical risk and development costs. TeleSoft focuses on developing the software and hardware so that you can focus on manufacturing and shipping your product.
