Abstract
The invention discloses a method for configuring simplified time slot transference replacement operation. The method comprises the following steps that: when a first channel and a second channel are the lowest-level channels, the time slot is transferred from the first channel to the second channel; if the first channel is configured with the time slot, the time slot is transferred from the first channel to the second channel; according to the method, the channels which are one level lower than the first channel and the second channel continue to be checked, until the time slot transference replacement operation from a first single plate to a second single plate is completed. Because the configuration theory of speed, level and time slot is introduced in the invention, thereby simplifying the operational process of some channels in which the configured time slot is transferred and replaced to another channel; in particular, when the cross unit of the selected transference channel is bigger, only simple operation is needed to achieve the similar effect before replacement, thereby greatly reducing the workload and lowering the error rate, and the operational process is direct-viewing, so that the user can easily understand the operational process.
