Used To Synchronize Operations And Maintenance Processes
May 08, 2018

A multiplexer is an integrated system that usually contains a certain number of data inputs and n address inputs (a data input is selected in binary form). The multiplexer has a single output that is the same as the selected data input value. Reuse technology may follow one of the following principles, such as: TDM, FDM, CDM, or WDM. Reuse technology is also used in software operations, such as: simultaneous multi-threaded information flow to the device or program.

Time division multiplexing refers to a technology that transmits multiple digitized data, voice and video signals, etc. on the same communication medium through cross-position pulses in different channels or time slots. The basic channel bandwidth used in telecommunication is DS0, and its channel width is 64 kbps. The telephone network (PSTN) is based on TDM technology and is often referred to as TDM access network. Telephone exchange supports TDM: DS0, T1/E1 TDM, and BRI TDM through some formats. The E1 TDM supports a 2.048 Mbps communication link and divides it into 32 time slots at intervals of 64 kbps. The T1 TDM supports a 1.544 Mbps communication link, which is divided into 24 time slots of 64 kbps each, of which the 8 kbps channel is used for synchronous operation and maintenance. E1 and T1 TDM were originally applied to the digitized voice transmission of the telephone company and did not differ from other types of data that appeared later. E1 and T1 TDM are also applied to WAN links. BRI TDM is provided through the Switch Basic Rate Interface (BRI, which supports Basic Rate ISDN, and can serve as a data channel for one or more static PPP links). The basic rate interface has two 64 kbps time slots. TDMA is also applied to the cell network of mobile wireless communications.
