Abstract: Disclosed are call processing methods which are performed by a network terminator located at a subscriber's premise. The network terminator is coupled to a digital network and a communication device at the subscriber's premise and can perform call waiting, caller identification, call conferencing without intervention from a telco's switching system that requires an additional charge to the subscriber for these services. In addition, the network terminator can perform a method which allows two digital communication devices coupled to one S-bus to share a communication session. In another embodiment, up to a six way conference call can be established with an analog telephone coupled to an ISDN network via the network terminator of the present invention.
