ADSI: Analog Display Services Interface

ADSI is an abbreviation of the "Analog Display Services Interface".

It is a technology of telephony that is used in the telephone services of plain old telephone service (POTS) or computer-based private branch exchange (PBX) telephone service. It operates in union with a screen-based telephone ("screen phone") or additional compatible customer-premises equipment (CPE) to make available the user with soft key access to Telephone Company or internal PBX custom calling features. It is an analog service for the reason that it uses analog frequency-shift keying (FSK) technology to work together with an LCD screen through small, low-band rate, downloads to restore and re-program soft keys in real-time.

  • In April 1995, the technology launched in the United States and turned out to Regional Bell Operating Companies (RBOCs) from Bellcore, which was almost immediately after the introduction of CLASS-based services through electronic switching system (ESS)), was promoted by the RBOCs who put into operation it, as an approach to make more efficient the entire accessible custom calling preferences through the use of a screen-based telephone; providing Residential and Small Business telephone subscribers PBX-like functionality at home or in small office/home office (SOHO) sites at a considerably minor price.
  • The service which first introduced before the assault of Personal Communications Service (PCS) and Voice over Internet Protocol (VoIP)-based telephony technologies turned out to be accessible and was, in the beginning, lined up to also put the effort in union with other kinds of services such as Enhanced Directory Assistance, telephone banking, movie theatre ticket sales, and further services that could work together with an LCD-screen.

Compatible equipment

  • U S West Communications, the foremost local RBOC to provide this service, promoted it as a "Home Receptionist" service. Home Receptionist service comprised a Nortel Powertouch (or Vista) 350 screen-based telephones and a "line-provisioning" service to make it functional. This service is at present provided by Qwest Communications (the descendant to US West), BellSouth and SBC Communications; however, the service has different marketing names.
  • Nortel put an end to the x5x telephone line and launched a highly reorganized updated version called the 39x-line and then afterward launched the 48x-line in 1998.
  • CIDCo and Cybiotronics afterward launched their lines of screen phones after the original Nortel Patent expired.
  • In 1999, Nortel sold off its CPE line to Aastra Technologies and Aastra carries on to promote and advertise these telephones through a variety of channels.
