(1) and accessing the network through a common dial-up telephone line.

In 2013, most internet access equipment such as a PC or a router is provided with a plurality of serial ports, and serial interface specifications such as RS-232 and the like are adopted between the serial ports and the Modem. The cost of the connection mode is relatively economic, the charging price is the same as that of the ordinary telephone, and the method is suitable for occasions with infrequent communication.
(2) The network is accessed through a special telephone line.

The access mode using the private line is not greatly different from the access mode using the ordinary dial line, but the dial-up connection process is omitted.

The use of this approach to achieve a connection to a remote location is a better remote approach because the public switched data network provides users with reliable connection-oriented virtual circuit services that are much more reliable and faster than the PSTN.
