BMUX Cabinet Drawing (Figure 28)
The BMUX cabinet drawing shows the position of each piece of equipment located in the BMUX cabinet. As you
can see in Figure 28, this particular BMUX cabinet contains:
l
One 2120 BMUX.
l
One 2001 audio panel containing an oscillator control switch module, a pre-amp monitor module, and a
microphone enclosure (ROW 4).
l
One 2001 audio panel containing an oscillator control board and an audio pre-amplifier (ROW 5).
l
One 2001 audio panel containing a tape player (ROW 6).
The following is written directly beneath ROW 6:
6 UNIT
CABINET 1 OF2
B-MUX
This indicates that the cabinet is a 6-unit cabinet, and that it is the first of two cabinets that will be installed side
by side. If you look at the drawing number (3981-743), you can see that there are two sheets to this drawing. The
second sheet of this drawing is the second cabinet. . .
in this case, the SCC cabinet, which we will discuss shortly.
Therefore, you know that the BMUX and SCC cabinets are to be installed side-by-side.
Now. . . the circled information to the right of ROW 6 in Figure 28 is enlarged below:

) TO SCC
Two male connectors are described, both of which will mate with a corresponding female connector at the SCC
cabinet. The male connectors are labeled 7M and 8M, respectively; once the BMUX and SCC cabinets are
installed, you should locate these M connectors. There will be associated female connectors in the SCC cabinet
labeled 7F and 8F, respectively. You should connect the connectors labeled 7M and 7F together; you should
connect the connectors labeled 8M and 8F together.
