what is MUX?

You are asking this in the network section, so I assume you mean a network MUX. Droby10 is correct. I personally have never installed a MUX anyplace. One of my clients has several to support their 10 year old DEC server. They were very often used with dumb terminals. The idea is that a building contains a bunch of dumb terminals that all plug into the MUX. Then the MUX connects (via phone line or leased line) to a server. At the server side of the connection is another MUX, which would break out that signal back into it's discrete lines.

I would expect that if you are looking at doing something with a MUX, you would be removing it and installing something newer. In my client's case, they now have traditional PCs with terminal emulation programs. So all their traffic goes over the normal TCP/IP network to the server.

Thanks for returning and finalizing your question.  Anytime you choose to grade less than an A, please comment as to why.  This helps all involved, including others who may visit this question at a later time for help.  Some experts look at grading history before deciding to help someone, so that also may have an impact to you and how quickly your future questions are answered.

The points to you are always the same, but the points granted the expert depend upon the grade.  Using 100 points as an example.  100 at A = 400 ... 100 at B = 300 .... 100 at C = 200, so it also has a point impact to the experts.  

If the grade chosen was in error, let me know, and I can correct this.
