Modem testing system and method

A modem testing method for use in a modem testing system comprising a switch, a line simulator, and a controller, the controller controlling the switch, the line simulator, and a plurality of items of customer premises equipment (CPEs) and a plurality of central offices (COs), the modem testing method comprising:

• loading testing specifications;
• setting up a mapping list of the CPEs and the COs;
• selecting testing specifications, and defining process values;
• setting up connections between the CPEs and the COs;
• simulating various types of lines and noise statuses;
• capturing and calculating bit error rates (BERs) of link data;
• displaying the link data, and testing results of amounts, if any, of one or more CPEs that fail the testing process and one or more IDs of the failed CPEs;
• and
• checking one or more of the process values in order to validate whether the whole testing process is completed.

A method for automatically testing multiple network devices used as customer premises equipment (CPEs) and capable of functioning via support of at least one central offices (COs), comprising the steps of:

• signal-communicably connecting a plurality of central offices (COs) and a plurality of customer premises equipment (CPEs) by means of a switch;
• setting up a simulator to simulate connection statuses between said plurality of COs and said plurality of CPEs through said switch;
• controlling said switch to establish a selective connection between a selective COs out of said plurality of COs and a selective CPEs out of said plurality of CPEs;
• urging said simulator to simulate said connection statuses through said selective connection for test purpose;
• and
• continuing said controlling onto said switch to establish a next selective connection between another selective COs out of said plurality of COs and another selective CPEs out of said plurality of CPEs.
