Zusammenfassung:	A system, apparatus and method for transmitting digital subscriber signaling are disclosed. The said method is applied to a packet core network that uses SIP as call control signaling. The said system includes a SIP subscriber adaption node which is used for providing the SIP signaling adaption function with which the ISDN terminal is accessed to the packet network using SIP as core network control signaling, and a ISDN service emulation control unit which is used for providing the ISDN service control function. The said method comprises the following steps: transmitting the SIP message encapsulating the digital subscriber signaling information between the ISDN service emulation control unit and the SIP subscriber adaption node, then realizing the information intercourse about the ISDN emulation and implementing the ISDN emulation service. In this manner, inheriting the ISDN service in the packet network is achieved.
