CAT-iq

Technology initiative Cordless Advanced Technology—internet and quality (CAT-iq) is a technology initiative from the Digital Enhanced Cordless Telecommunications (DECT) Forum, based on ETSI TS 102 527 New Generation DECT (NG-DECT) European standard series. NG-DECT contains backward compatible extensions to basic DECT GAP (Generic access profile) functionality which allow bases and handsets from different vendors to work together with full feature richness expected from SIP terminals and VoIP gateways. CAT-iq defines several profiles for high quality wideband voice services with multiple lines, as well as low bit-rate data applications. Profiles The CAT-iq profiles are split between voice and data service, with the following mandatory features: CAT-iq 1.0 "HD Voice" (ETSI TS 102 527-1) Narrow-band (32 kbit/s G.726 ADPCM) and wideband (64 kbit/s G.722 sub-band ADPCM) audio, calling party line and name identification (CLIP, CNAP) CAT-iq 2.0 "Multi Line" (ETSI TS 102 527-3) Adds multiple lines, line name/id, call waiting, call transfer, phonebook, missed calls list, DTMF signalling, hands-free headset, handset locator, synchronisation of call lists, phonebook, and settings CAT-iq 2.1
