<p>PURPOSE:To quicken transmission between units by providing a frame aligner in a slave unit and an elastic storage for absorbing transmission delay between units in a master unit and sending a frame pulse in 2-way between the units. CONSTITUTION:A pulse generating circuit 2 as a signal generating means and an elastic storage 3 are provided in the master unit 1 and a frame aligner 5, a delay circuit 6 as a signal generating means and a loopback signal line 11a are provided in the slave unit 4. Then a frame pulse is sent in 2-way between the units 1 and 4. Thus, the frame aligner 6 is arranged while being distributed in separate units to attain high speed inter-unit transmission thereby applying the system to a synchronizing terminal station equipment with high speed and large capacity or the like easily. Moreover, the capacity of the elastic storage is reduced to a degree equivalent to the unit transmission delay quantity.</p> |
