Method, system and apparatus for synchronizing time in time-division multiplexing system
A method, system and apparatus for synchronizing time in a time-division multiplexing (TDM) system are disclosed. The method may include: receiving time synchronization information carried in an idle timeslot, where the idle timeslot is in a multiframe of an E1 signal or T1 signal; and synchronizing time according to the time synchronization information carried in the timeslot. The present disclosure may synchronize the time of the communication device in the TDM system while saving the cost, eliminating the necessity of installation and improving the stability of the time synchronization.
