CAT-iq HD Voice

CAT-iq is a key voice and networking technology in home gateways. CAT-iq stands for Cordless Advanced Technology - internet and quality.

The underlying ETSI standard for CAT-iq is called DECT New Generation. This is the basis for the transformation of the DECT technolgy from the Public Switched Telephone Network (PSTN) to an all IP network. 

CAT-iq integrates the DECT base station into the home gateway, giving it native IP connectivity for voice and data services.  This increase in bandwidth make new operator services possible. Many of the voice related services are part of the SIP extended services profile and include features like call forwarding, multiple lines, event notification and many more. CAT-iq also enables HD Voice and CAT-iq certified devices may make use the HD Voice logo from the GSMA.

CAT-iq 2.0 is also accompanied by the DECT Forum certification program. Certification can be gained by fulfilling tests for Audio, RF and protocol. Certified CAT-iq 2.0 handsets from different system vendors can be used on the same certified base station. They are interoperable with other CAT-iq handsets and gateways as well as being backward compatible to DECT GAP products. 

CAT-iq 2.1 adds extended functionality like conferencing and improved power saving functionality. CAT-iq 2.1 also contains CAT-iq 1.0 and 2.0 within its functional scope and is backward compatible to both. The accompanying certification program is similar to the program for CAT-iq 2.0 with the additional requirement of an application test suite which uses a test bench and several golden devices to prove the interoperability of certified devices all of which serves to greatly improve the user experience.
