1. A method of maintaining routing data identifying the physical circuit node interconnection terminals through which a given communication line circuit passes in a telecommunications network which comprises at least one switch and a test apparatus having a predefined telephone number, said method comprising the steps of:

  • dialing the predefined telephone number of said test apparatus from a telephone instrument connected to a terminal in a node of a telephone line circuit through which the line passes;

    said test apparatus retrieving the calling line identity data of the line circuit from which the call is made and which therefore passes through said terminal to which the telephone instrument is connected;

    said test apparatus inviting the user of said telephone instrument to enter an identifier for a terminal through which said telephone line circuit passes;

    said user entering an identifier for one of a pair of terminals within said node through which said telephone line circuit passes; and

    said test apparatus storing the calling line identity and the terminal identifier entered by said user in a database containing a routing table storing routing data in which the calling line identity for each line circuit is recorded against identifiers for the terminals within the nodes through which the line passes.
