the signal bearing the negotiation message is a level signal in an R3232 form, after the first level conversion module converts the level signal in the RS232 form into a level signal in an LVTTL form, the analysis processing module analyzes the negotiation information, whether the negotiation is successful is judged, and after the negotiation is successful, the controller controls the change-over switch 1 and/or the change-over switch 2 to start the function module and the level form corresponding to the main PTN. For example, assume that the primary PTN is configured to: the external clock function is selected with the selected HZ signal having the level criteria of E1 and the selected channel numbers of 3 and 6, then the slave PTN, when configured, also selects the external clock function with the selected HZ signal having the level criteria of E1 and communicates with the master PTN via channels 3 and 6. After configuration is completed, the slave PTN can normally communicate with the master PTN, and clock synchronization is completed.
