we mean telecom

 
Our declared goal is to introduce refined, blended Open Source softswitch solutions into the telco market. As open source projects like Asterisk, Trixbox and Yate have become mature over the past decade and CPU power of standard Intel based servers almost doubles every year, now it’s the right time to have a look at cost effective, standard based telco size solutions for your demands. These often exceed the power and flexibility of the sometimes over – engineerd yet feature lacking products of leading vendors.

Carrier Connect’s offering is the takeover of all implementation- related tasks and the delivery of bullet proof turnkey solutions with 24/7 support, pre- and postsales!


 

complexity meets versatility

 

Carrier Connect employees grew up in the Telco domain. Not only because of this our staff has an idea of the interworking complexity in today’s Telco networks, be it fix or mobile. Implementation cycles shrink while the demand for even more and more flexible customer applications steadily increases. Not to neglect all the implications that come with migration towards network technologies beyond 3G.

Carrier Connect responds to such specific requirements by leveraging Open Source components and open standards wherever we can. This gives us the freedom as solution prvider to react to certain prereqiuisites in a much more flexible and cost effective way than practically any other system vendor.

we think green, too

 

We build our systems on the smallest thinkable carbon footprint. Systems of similar magnitude require approximately ten times more power, cooling and space. We integrate the highest channel density on the market in a 1U Server. The TREX multi- core systems can replace up to 10 state of the art Asterisk installations. Further more, the chassis are equipped with highly efficient power supplies which comply to the latest environmental standards.

under the hood

 
Architecture:

The entire software runs within a fully virtualized environment. This means one headache less for the maintaining engineers. Our systems are fully field upgradeable. The internal call distribution to the various softswitch instances is handled by the dominant SIP router Kamailio.

unique

 

Other than competitor’s softswitch concepts, the CPU consuming transcoding is done by highly integrated DSP hardware built in. This measure increases the amount of channels as well as cps ratio by factor 3-4, compared to pure Host CPU based softswitches. Further more, cpu- intense tasks like videocoding, conferencing as well as RTP encryption (SRTP) can be outsourced to the DSP hardware. Our concept of virtualization is based upon a number of system requirements:

High availability:
By means of redundant design of the softswitch- cores a high degree of reliability can be achieved on the servers.
Performance:
Despite a potentially good implementation, some softswitch cores tend to not scaling well. In order to improve this behaviour, virtualization can be a key factor.
Flexibility:
Since many different open source softswitch projects have emerged over the past, we are able to offer virtually any type of softswitch installation.
Manageability:
Remote maintenance in a virtualized environment is much simplified.

Product

All this?

 

Yes, Asterisk and else can be programmed to fulfill random application based telephony tasks like IVR, call generation, call transfer, transcoding, media relay. Most Voice and Video Applications one may think of are supported.

G.711, GSM, G.729 as well as many other codecs like H.264 Video come with the softswitch at no extra license fee.
Applications that are known to run on actual Installations comprehend among many more:

  • Televoting
  • Alarming
  • Centrex PBX switching platform
  • SS7 interconnect with other telcos
  • ENUM VoIP routing

better every day

 

From audiotex services to full centrex solutions, the ongoing open source softswitch developments support every facette of today’s requirements by the ever expanding telco service portfolio. New features are requested ? Every new release brings in a bouquet of cutting edge features. Since our softswitch is Open Source, Carrier Connect is happy to modify the Software to any extent the customer requests.

Televoting

 

What is the challenge:

Carrier Grade IVR applications such as Televoting are designed to accept and process a large number of parallel calls. A high overall channel capacity is mandatory here as well as high call setup rates (cps).

TREX 6000 can process up to 6000 semi- parallel calls.

Carrier / Alternative Carrier

 

Market Segments:

  • ILECs / CLECs
  • Cable Network Providers
  • MAN Providers
  • VoIP Providers
  • Cellular Providers

Software replaces Hardware:

As traditional, dedicated TelCo Hardware like ss7 gateways, telephony switches and audio servers become out of vogue, the functionality of such network elements today can be integrated in  a single TREX system.

Of course TREX meets all requirements of a Telco Grade Installation: High channel density and SS7 signalling.

Regular updates are oriented by the ongoing development of the open source community.

Example Scenario:

Alarming and Mobilization

 

What is the challenge:

  • alert, mobilize and inform groups of variable size
  • quick, simple and flexible
  • alarm calls with highest priority can override standard calls
  • system should allow feedback of every individual subscriber
