Abstract

Enhanced speed calling is provided on a network basis for public access telephone stations such as coin telephones and wireless public Telepoint services stations. The system permits single digit access to voice recorded announcements regarding long distance dialing instruction and service provider identification information. The dialing of a common generic abbreviated code word triggers the delivery of a pre-established interexchange carrier recording identifying the presubscribed carrier to the user at the calling public access telephone station. The information card presently utilized at public access telephone stations, such as coin stations, is replaced with a generic card providing information to lead the caller to use the abbreviated code word to initiate identification of the presubscribed interexchange carrier for that public access telephone station. The speed calling feature also permits the use of generic abbreviated code words to obtain connection with public service providers convenient to the public access telephone station from which a call is made. The enhanced speed dialing is adapted to all stored program control switches without the addition of extra equipment and concomitant capital investment.
