摘要： 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.

摘要： A method for effecting bandwidth-on-demand, multiple digital channel connections between network subscribers, wherein each of a series of call requests from a given network subscriber to a given recipient establishes a connection via a restricted tandem switching arrangement. The switches within the network facilitating this method are each programmed to utilize inter-switch paths having essentially equivalent electrical delays when effecting connections for calls dialed by network subscribers designated as bandwidth-on-demand users, resulting the virtual elimination of inter-channel differential path delays.
