If you've got enough arms on the star and they're close together,
consider using the following hardware-saving scheme. Instead of this:

  [Mac] [Mac] [Mac] [Mac] [Mac] [Mac]
    |     |     |     |     |     |
    |     |     |     |     |     |
    |     |     |     |     |     |
  [ Star Controller in central closet ]

Connect the ends of your star using the normal PhoneNet boxes
in the office, and jumpers in the wiring closet ("[]" represents
PhoneNet boxes). Create the following topology:

  [Mac] [Mac] [Mac] [Mac] [Mac] [Mac]
     [] []       [] []       [] []
    +-----+     +-----+     +-----+
    |     |     |     |     |     |
    |     |     |     |     |     |
    |     |     |     |     |     |
  [ Central Patch Panel ............]
          |     |     |     |     |
          +-----+     +-----+  [FastPath]
	  Jumper      Jumper

Remember to terminate the ends, stand by for disruptions when people
disconnect things they shouldn't - Star controllers (of any brand)
save you from this.
