            What is PSTN/ISDN/SIP/IMS?

            PSTN
            A traditional 2-core telephone line from the operator to the subscriber side, or an N pair of 2-core telephone lines coming out of the xPon unit. Each pair of telephone lines corresponds to a number and is connected directly to the FXO port of the New Rock IP-PBX.

            ISDN(E1/T1)
            A dedicated 2M line from the operator to the user side, also called E1 line. 1 E1 line supports 30 concurrent calls and N telephone numbers. There is no E1 interface on the New Rock IP-PBX, the user needs to use the New Rock Digital Trunk Gateway MX100G-S to connect to the E1 line.

            SIP
            The New Rock IP-PBX can register upwards to the SIP platform through the Internet using this standard SIP extension.

            IMS
            The New Rock IP PBX can interwork with an IMS private line from the operator to the subscriber which includes two key components.
            1) Network information of the IMS private line: including IP address, subnet mask, default gateway, DNS, etc.
            2) Server information of the IMS private line: including IP address and port of the registered server, SBC address, domain name information, IMS account number, password corresponding to the IMS account, etc.
