1. A circuit termination method comprising:

  • updating a transmission speed according to a condition of a circuit between a first circuit terminating apparatus and a second circuit terminating apparatus,performing a service suspension and resumption of a predetermined bit position common to each frame of a multi frame,adjusting inputting speed and outputting speed of a terminal connected to the first circuit terminating apparatus to the updated transmission speed between the first circuit terminating apparatus and the second circuit terminating apparatus, anda re-negotiation is performed between the first circuit terminating apparatus and the second circuit terminating apparatus starting from a speed faster than a contracted speed of the terminal connected to the first circuit terminating apparatus when frame synchronization between the first circuit terminating apparatus and the second circuit terminating apparatus monitored is lost for a period longer than a predetermined period, and the synchronization is established again for a period longer than a predetermined period.
