ISDN access to a telecommunications network is provided to customers at different locations by sharing a D-channel controllers (DCC's) positioned within the network in close proximity to the ISDN-capable toll switches serving those customers. The customers provide call set up parameters to a DCC via a user interface system (UIS) at the customers premises that communicates via a dial-up data connection with a respective user support system (USS) connected to the DCC. The DCC in turn formulates ISDN signaling messages that are sent to the switch via a PRI interface and set up an appropriate communications path through the network to a desired destination. Data originating in customer premises equipment is received in the switch via a T1 access line operating in the 'non-facility associated signalling' mode. Alternatively, a central USS located in a control center within the telecommunications network, transmits, via dial-up data connections, signalling information to individual USS's supporting associated DCC's.

Method and apparatus for providing ISDN access

A method of administering a sequence of locations to which calls placed to a subscriber's personal telephone number may be routed for personal communication service by a) storing pre-defined mnemonic audible tags for association with telephone numbers prior to any interactions with the subscriber, b) offering the subscriber a choice of the pre-defined mnemonic audible tags by speaking them to him, c) receiving an indication of the mnemonic audible tag selected by the subscriber, d) receiving signals indicating a telephone number supplied by the subscriber and e) storing the received telephone number information in association with the selected mnemonic audible tag. The mnemonic audible tags are then used in place of their respective associated telephone numbers in administering the sequence of locations. A mnemonic audible tag is a meaningful word indicative of the actual location, person, or service, e.g., 'office', 'neighbor' or 'AT&T voicemail', to which a call to the personal telephone number is to be completed. Advantageously, administering a sequence of locations is accomplished by simply manipulating friendly, meaningful and easy to understand terms rather than cumbersome and meaningless, telephone numbers or codes.

Technique for administering personal telephone numbers

A subscriber can dynamically provision, i.e., assign desired characteristics to any 'target station', which is an active phone accessible to a telecommunications network. A call thereafter originated from the target station (including a pay phone or a mobile phone) then can use customized features (for example, speed calling, conferencing, account code dialing) and take advantage of special corporate billing arrangements (for example, SDN, WATS and MEGACOM). The identity of the target station with respect to the communications network (e.g., the Automatic Number Identification (ANI) of the station) is not changed. Initially, a service profile is created and stored for each subscriber, containing information describing desired features and billing options. Thereafter, the characteristics of a particular target station are changed by an activation process that can be initiated from any location, whereby the ANI associated with the target station is entered into the ANI trigger table in an intelligent switch on which that station is homed, and the service profile is loaded into a database. When a call is originated in the target station, information in the database is applied to the switch to provide the desired characteristics.
