BOARD PLUG-IN ek-MPX/8

“8/E1 ADAPTER”

The EK-MPX/8 board is an 8E1 interface data flows that allows the
multiplexer and demultiplexer operations between a transport
stream and a 4E1 or 8E1 data flows.
The structure of the EK-MPX/8 can be divided in the multiplexer Features
section and in the demultiplexer section as the block scheme
showed in the next page.  8E1 Adapter
In the multiplexer section, the input transport stream is switching
by the Mux on/off, so we can have the stuffing signal generated by  Baypass protection
the stuffing generator or a transport stream coming from another  Remote telecontrol
board. The 4E1 mux blocks allows the multiplexer operation of the  Multiplexer embedded

transport stream and send to the modulator (EK-UNM/3). Management
In the demultiplexer section, the demodulated transport stream is
selected by the sel in block. It is possible to select the transport
stream coming from the demodulator (EK-UNM/3) located in the
same EK-MFR/2 unit (IN 1) or a transport stream coming from the Applications
demodulator located in another EK-MFR/2 unit (IN 2). When the
signal is selected, the data stream is send to the 4E1 demux blocks  Digital Microwave Links
