Abstract
This subscriber access unit includes an electronic subscriber line interface circuit (1) whose functions include: cell header translation, routing label addition and bit rate control (policing). It further includes concentrators (2) including electronic statistical time-division multiplexing devices (34.1, . . . , 34.16) and electronic periodic time-division demultiplexing devices (47.1, . . . , 47.16) and a photonic wavelength-division multiplexing and bit rate changing device (38), a photonic periodic time-division multiplexing without wavelength-division multiplexing device (40), a photonic bit rate conversion and wavelength-division demultiplexing device (43) and a photonic periodic time-division demultiplexing and wavelength-division multiplexing device (41). This structure optimizes use of photonic technology and electronic technology to achieve a minimal implementation cost.
