ABSTRACT:
An instantaneous switching unit for a delay/priority control buffer comprises an operational buffer and a standby buffer, wherein, upon detecting phase adjustment cell out of received signal cell, the operational buffer recognizes the amount of main signal cell which has been received before the phase adjustment cell is detected, the main signal cell staying waiting for the timing when it is read out, and notifies the standby buffer of staying amount information indicating the presence of the main signal cell staying there as well as the staying amount thereof, while the standby buffer controls the reading operation of the main signal cell according to the staying amount information received from the operational buffer upon detecting the phase adjustment cell out of the received signal cell.
