說明書
Most fields in an overhead area are fields used for a management channel, or are occupied by a management channel. However, these fields are not fully used. In this embodiment of the present invention, a first field is defined in an overhead code block of each physical connection. The first field indicates an identifier of a timeslot configuration table used by a current physical connection, and is used to transmit, when the timeslot configuration table changes, content of a changed timeslot configuration table to a receive end using the management channel. That is, a specific field needs to be defined only for the identifier of the timeslot configuration table in the overhead area, and the content of the timeslot configuration table is transmitted over the management channel. This effectively reduces a waste of overhead resources, and provides higher flexibility.
Optionally, in an embodiment, M overhead code blocks transmitted over each physical connection may be all used for the management channel. Table 2 is used as an example for description in the following. Table 2 shows a definition manner of an overhead area according to an embodiment of the present invention.
