ABSTRACT:
An interface apparatus for SDH/SONET interconnection includes a transmission interface section provided at a position where an apparatus of the SDH system and an apparatus of the SONET system face each other and adapted to transmit a signal toward an apparatus of a different system. The interface apparatus for SDH/SONET interconnection further includes a mode setting unit for setting a mode suitable for an apparatus of a counterpart system, a frame synchronization information inserting unit provided in the transmission interface section and adapted to insert frame synchronization information corresponding to the mode set by the mode setting unit, and an overhead information inserting unit provided in the transmission interface section and adapted to insert overhead information corresponding to the mode set by the mode setting unit. This structure makes is possible to easily interconnect apparatuses of different systems (apparatuses of the SDH system and the SONET system) so as to operate them.
