Document Type and Number:
Japanese Patent JP2000508872
Kind Code:
A
Abstract:
The invention concerns a method for inserting a service channel in the service channel plesiochronous frames. The method also consists in transmitting a time source block between a transmitter and a receiver of the frame, said method consisting in reserving in the frames, at transmitter level, at least a site for carrying the service channel data. The method is characterised in that it consists in: at the transmitter level: (i) inserting blocks (B) of the service channel in the reserved sites preceding each of these blocks (B) by a predetermined number n1 of identical bits (D), called start bits, and observing the following rules: in case there is no need for stuffing the remaining sites, starting the process at step (i) for a new block (B); in case there is need for stuffing the remaining sites, following each of the blocks (B) by a predetermined number n2 of identical bits (F), called stop bits, the stop bits being different from the start bits (D), and starting the process at step (i) for a new block (B); at the receiver level: detecting the regular occurrence of start bits (D) or the regular occurrence of start bits (D) preceded by the stop bits (F), for determining the presence of the blocks (B) in the reserved sites and extracting these blocks (B) from the reserved sites.
