1.
Add up all the cable distances per classroom to calculate the total distance. See the
second column in the example that follows.
2.
Locate the cable that your are using in Table 5. Divide the Total cable distance
that you calculated in the previous step by the “Maximum Distance per
AXLINK
Port on the
RANEXP
or
RANBROAD
.”
3.
The number that you arrive at will determine the number of
RANEXP
or
RANBROAD AXLINK
ports needed (see the last column in the table below). If the
number you arrive at is larger than 12 for the
RANEXP
or 10 for the
RANBROAD
,
you will need to add an
RANEXPAD
or another
RANBROAD
.

The number of punch blocks (

cable runs and the way you configure the
RANEXP
or
RANBROAD
ports.
