Abstract
In an SDH transmission unit, a tributary block includes a plurality of routing blocks for accommodating low speed line signals of a predetermined capacity and performing line selection processing of the low speed line signals to be interfaced with a high speed block in accordance with a form of a tributary network. The form of the tributary network includes various line speeds and network configurations. At least one of the routing blocks serves, when the low speed line signals accommodated therein do not fully occupy the predetermined capacity, as a master block which accommodates at least one of the other routing blocks as a slave block in order to accommodate the low speed line signals accommodated in the other routing block.
