10.5.5 Distance Limitations
The SU uses shielded outdoor rated CAT5 cable between the installed unit and the indoor
junction box. For the unit to receive acceptable voltage to operate, this cable is limited to 60
meters. Between the junction box and the customer premises PC (or hub, Ethernet Switch,
Router, etc.), the system uses standard indoor CAT5 cable, which is rated for a maximum
functional distance of 100 meters when running the Ethernet 10BaseT interface. For an AP (or
SU) connected via ATM25, the distance limitation of the data signaling is 270 meters.
