A device and method for interfacing with an advanced switching (AS) platform is provided. In the uplink direction the device includes: a line side interface processing module, which receives SDH/SONET frames and conducts frame header searching and descrambling; a de-framing processing module, which de-frames the descrambled frames to obtain the payloads; a packaging module, which packages the obtained payloads into AS packets according to the packet format of the AS platform and transmits the AS packets to the AS platform through the AS interface processing module. In the downlink direction the device includes: an AS interface processing module, which receives AS packets switched by the AS platform; an un-packaging module, which conducts un-packaging to obtain the payloads of the AS packets; a mapping module, which maps the payloads into SDH/SONET frames; a line side interface processing module, which scrambles the SDH/SONET frames and transmits the frames to the SDH/SONET network.
