RS 422 LIF LINE RATE SETTING
LINE RELATED
SUMMARY:
Set the rate of communication to and from the connecting conference terminals.  
The rate can be set independently for each package of RS 422 LIF (LIF 1 to 4).  
However, it must be noted that conference terminals having different rates cannot 
be connected to each other, nor can be permitted to participle in the same 
conference.

RS 422 LIF CLOCK SOURCE SETTING
LINE RELATED
SUMMARY:
Specify the line from which to extract the line clock to be used inside the MCU 
5000A.  When set to “auto”, the line whose line signal is the first to turn normal 
will be specified as the clock source, but it will be replaced by the lowest-
numbered line currently in normal operation once the line acting as the clock 
source then ceases being normal.  When all the...
