Integrated analog/digital telephone network interface circuit design
A remote terminal for use at an access network node of a network provides a plurality of telecommunications services, the remote terminal providing selected ones of the telecommunications services to at least one corresponding terminal device. The telecommunications services provided by the network include a plain old telephone service (POTS), a an integrated service digital network service (ISDN), and internet services such as xDSL. In one embodiment, the remote terminal comprises: a digital signal processor coupled for communication with the network, the digital signal processor having a plurality of terminal ports; and a plurality of subscriber line interface circuit (SLIC's), each of the SLIC's providing an interface between a corresponding one of the terminal ports and at least one corresponding terminal device, the digital signal processor being configured to provide selected ones of the telecommunications services to corresponding ones of the terminal devices. In another embodiment, the remote terminal comprises: a digital signal processor coupled for communication with the network; a subscriber line interface circuit (SLIC) providing communication between a particular terminal device and the digital signal processor; a memory unit for storing computer readable instructions for execution by the digital signal processor, the instructions for implementing an adaptive telecommunications service process including the steps of: automatically determining a selected one of the telecommunications services required by the particular terminal device, and providing the selected telecommunications service to the particular terminal device.
