In addition , the simple sdh multiplexer has special use because of its small and exquisite character . the e1 multiplexer which the dissertation focuses on is a subsystem of the 2 . 5g terminal multiplexer ( the specific demultiplexer of sdh ) . its function is tapping e1 signal from stm - 1 and multiplexing e1 signal into stm - 1 本文所研究的e1映射复用模块,是2 . 5g终端复用器( sdh专用分接器)的一个子系统,它所实现的功能就是从stm - 1中分接出e1信号以及把e1信号复用进stm - 1 。
A terminal multiplexer is a software application that can be used to multiplex several virtual consoles, allowing a user to access multiple separate terminal sessions inside a single terminal window or remote terminal session. It is useful for dealing with multiple programs from a command line interface, and for separating programs from the Unix shell that started the program.
