Abstract
In a terminal interface, signal data of a terminal is carried on a multi-frame having a period of one per an integral number of the frame period of a digital channel. The terminal interface is connected to a multiple portion through a time division switch. The multiple portion picks up the signal data in the multi-frame with a bit unit and multiplexes them, and a transmission route interface transmits the multiplexed signal data along a high-speed digital line.
Claims12
A time division multiple equipment, comprising:
- a plurality of terminal interfaces, wherein each terminal interface carries low-speed data from a data terminal equipment on a multi-frame having a period of one per an integral number in a frame period of a digital channel of a previously set basic speed;
- a multiple portion for multiplexing a signal bit with a bit unit by picking up only the signal bit of a data signal from the data terminal equipment in the plurality of multi-frames on which the data signal from the plurality of data terminal equipment are carried, and by mapping the signal bit in accordance with a content written in a mapping table;
- and
- a transmission route interface for matching a series of bits, multiplexed by the multiple portion, with a transmission speed of a high-speed digital line and for transmitting the series of bits to the high-speed digital line.
