Non cordless house phones for voip series#
These were the ETS 300-175 series in nine parts defining the air interface, and ETS 300-176 defining how the units should be type approved. The DECT standard was developed by ETSI in several phases, the first of which took place between 19 when the first round of standards were published. It also requires mandatory support for wideband audio.ĭECT-2020 New Radio is a 5G data transmission protocol which meets ITU-R IMT-2020 requirements for ultra-reliable low-latency and massive machine-type communications, and can co-exist with earlier DECT devices. CAT-iq allows interchangeability across IP-DECT base stations and handsets from different manufacturers, while maintaining backward compatibility with GAP equipment. The New Generation DECT (NG-DECT) standard, marketed as CAT-iq by the DECT Forum, provides a common set of advanced capabilities for handsets and base stations. Japan uses its own DECT variant, J-DECT, which is supported by the DECT forum. GAP-conformance enables DECT handsets and bases from different manufacturers to interoperate at the most basic level of functionality, that of making and receiving calls. The DECT standard includes the generic access profile (GAP), a common interoperability profile for simple telephone capabilities, which most manufacturers implement. The ULE Alliance's DECT ULE and its "HAN FUN" protocol are variants tailored for home security, automation, and the internet of things (IoT). DECT can also be used for purposes other than cordless phones, such as baby monitors and industrial sensors. However, its most popular application is single-cell cordless phones connected to traditional analog telephone, primarily in home and small-office systems, though gateways with multi-cell DECT and/or DECT repeaters are also available in many private branch exchange (PBX) systems for medium and large businesses, produced by Panasonic, Mitel, Gigaset, Cisco, Grandstream, Snom, Spectralink, and RTX Telecom. DECT has almost completely replaced other standards in most countries where it is used, with the exception of North America.ĭECT was originally intended for fast roaming between networked base stations, and the first DECT product was Net 3 wireless LAN.
This forced development of a variation of DECT called DECT 6.0, using a slightly different frequency range, which makes these units incompatible with systems intended for use in other areas, even from the same manufacturer. North American adoption was delayed by United States radio-frequency regulations. īeyond Europe, it has been adopted by Australia and most countries in Asia and South America. It originated in Europe, where it is the common standard, replacing earlier cordless phone standards, such as 900 MHz CT1 and CT2. Digital enhanced cordless telecommunications (Digital European cordless telecommunications), usually known by the acronym DECT, is a standard primarily used for creating cordless telephone systems.
