Example

This example illustrates a proper network plan. All cable distances given
assume that 24 gauge Type 3 cable is used in the network. See Figure 13.
Figure 13. Example
Assume that a network is desired which has devices located on three
floors of a building, and four MAUs will be used. Using the cable lengths
shown in Figure 13, the total length of the main ring is 125 feet (35 + 30 +
60). The patch cable connecting MAUs 2 and 3 has been ignored. Its
length is insignificant, and it is assumed that if it goes bad it will be
replaced instead of looping the ring onto the backup path. The ARL is 95
feet (total main ring length minus the shortest segment: 125 – 30).
