Claim:
1. A transmission apparatus including a plurality of plug-in units each executing a part of functions of the transmission apparatus, the transmission apparatus comprising: a first plug-in unit of the plurality of plug-in units configured to include: a clock generator configured to generate a first clock signal, a first frame pulse generator configured to generate a first frame pulse signal based on the first clock signal; a detector configured to compare a first phase of the first frame pulse signal with a second phase of a second frame pulse signal transmitted from other plug-in unit of the plurality of plug-in units, detect a phase difference between the first phase and the second phase, and generate phase difference information based on the phase difference detected, and a first transmitter configured to transmit a control signal including the phase difference information to the other plug-in unit; and a second plug-in unit of the plurality of plug-in units, being the other plug-in unit, configured to include: a receiver configured to receive the control signal transmitted from the first plug-in unit, a controller configured to control a phase of a second clock signal generated by the second plug-in unit, based on the phase difference information included in the control signal, a second frame pulse generator configured to generate the second frame pulse signal having the second phase based on the second clock signal, and a second transmitter configured to transmit the second frame pulse signal to the first plug-in unit.
