FAIRDEAL INFOSYSTEMS Since 1996

The IRIS has been designed to support all the Networking protocols of the ISDN network. IRIS supports Q-Sig networking over predominant protocols like BRI and PRI.

In today's dynamic and changing world even 56 Kbps is not sufficient access speed by international standards and hence there is a need to support even higher speeds on the same copper wire. This bottleneck in the download speeds led to the development of DSL technologies. DSL are digital subscriber lines, which basically involve supporting higher bandwidths over existing copper wires & the technology involves simultaneous use of same copper wire for voice as well as data transmission.
IRIS has designed built in cards that will offer one of the following flavours of DSL- ADSL, S.shdsl, VDSL which are available today, catering to different segments of the market. This will facilitate the following:

Traditional Internet users make use of a dial up connection for getting connected to the Internet. Normal analog modems used for this purpose cannot support a bandwidth of more than 56kbps but even these speeds are not achievable behind most PBXs. Internet access speeds from ordinary pushbutton telephones behind high end digital PBXs available in India today is limited to as little as 28 Kbps (theoretical 32 Kbps) while P&T network allows 56 Kbps (theoretical 64 Kbps) this is because of the type of Codecs used in most digital PBXs. It may be recollected that PBX was designed as a Voice switch & bandwidth requirements for voice communication is only around 3.4 Kbps hence such devices were perfectly suitable as voice switches. Indian customer has not felt the need for this upgrade because effective data download speeds here are still far lower than 28 Kbps hence data carrying capacity of the channel has not become a bottleneck. Now with higher bandwidth availability in the country the maximum data carrying capacity of the channel will become major determining criteria.

IRIS uses a Codec named "Duslic" that would provide 64 Kbps data connectivity on the analog extensions hence you can access full capabilities of the P&T network even behind the digital PBX.

IRIS provides integrated solutions for circuit switching & data switching needs of corporate business houses using a single device. IRIS has an in built Voice over IP cards for supporting long distance communication over Internet. These VOIP cards have powerful DSP's for doing voice compression, echo cancellation, comfort noise generation and packetisation. Gateways and gatekeepers based on H.323 are inbuilt in these cards. The gatekeeper software does the routing of the voice packets to various destinations through the Internet. Various applications like least cost routing, private networking etc. can be implemented using these VOIP cards. Using these VOIP cards, it has become possible to reach any extension user in the PBX from any part of the world through the Internet

The switch will essentially have the ROUTER capability whereby it would allocate IP addresses to each analog & digital extension user to be able to integrate data switching & dynamic bandwidth allocation to the user extensions. Such ROUTER capabilities providing independent Ids can have additional advantages like setting up a pool of extensions for receiving Fax, voice mail or modem calls. ROUTER capabilities would further allow telephone & data calls to be routed by name as well. We target to provide very cost effective solutions of data switching built into our voice switches, but without the fancy frills, of a pure data switch, that are essentially needed in an ISP kind of an environment.

Such voice & data servers would also essentially shrink the telecom world much the same way as Internet has brought people together. Once the switch is connected to the IP cloud then, you are connected & there is no significance of distance, much the same way as while downloading from Internet.

Switches are becoming increasingly complex & in this world of specialization there is a need where switches should be built on open standards where hardware of multiple vendors could function under the software designed by certain other vendors. Solutions in the form of Soft-switches will be available from multiple vendors, at all levels who supply open standards-based products & Customers are free to choose best-in-class products to build their network. Solutions can come from multiple vendors, at all levels who supply open standards-based products & customers would be free to choose best-in-class products to build their network. Open standards would enable innovation and reduce costs. These platforms will enables and accelerate the creation of new "converged" services & increased network flexibility that would provide support for multiple applications from a single platform.

                                                                  

         Soft-switch specifications are still being formalized hence the IRIS has been designed on a compact PCI supported IP backbone platform that would be easily adaptable to conform to the open standards. We are designing all our new platforms on the IP backbone, which means that we would be able to integrate sub-modules of our PBX over the Ethernet or in a distant future even across the IP cloud. This can further lead to remote PBX been spread across geographically distant offices and all of them would be connected over static IP addresses to provide a communication system that would make these geographically distant offices feel as if they are all operating under the same switch. Such IP based PBXs can have the control cards located at yet another place on the IP cloud.
 

In today's environment it is more important than ever before to receive caller identification on your telephone even before you pick up the phone. It is a valuable safeguard against hoax calls & other security threats & for this very reason several airlines have made it mandatory to install telephone systems that support CID/CW facility whereby the caller name is displayed on the telephone even before the call is received. While most PBX s display this CLI on the specialized digital extensions using proprietary Key phones (price around Rs 8000), we provide it on the ordinary analog extensions using standard CLI phone available in the market (price Rs 800).

Further it is important that CLI is transferred to the extension user if the call is transferred from one to another. While some PBXs support CLI on key phones but will not transfer it to the extension where call is transferred. We not only support CLI on all extensions, we also transfer it along with the call so that each time a call is received, identification of the caller is received along with it & the receiving station can make a note of it even before the call is actually handled. It is possible to even take print out of calls received along with details of CLI.
