E-FL-HB-0x00 in Half-Duplex Network  
CABLE SPECIFICATIONS  
The 5-4-3 Rule applies separately to each collision domain. NOTE: A  
collision domain is any Carrier Sense Multiple Access with Collision Detection  
(CSMA/CD) network in which a collision will occur if two attached stations  
transmit at the same time. A segment is the cable connection between two  
network interfaces.

USING THE 5-4-3 RULE:  
Maximum Cable Length:  
Maximum number network connections:  
Minimum distance between connections:  
Terminate 10BASE-2 cable at one end using a 50 ohm terminator and at the other end  
using a 50 ohm terminator grounded to earth ground.  
The 5-4-3 Rule allows no more than five segments in any 10-Mb/sec  
Ethernet collision domain, no more than four repeaters (hubs) and no  
more than three populated segments (10Base-2 or 10BASE-5 coaxial-  
cable installations).  
0.5 meters (1.6 feet)  
To determine the size of the collision domain by assigning segment  
numbers to cable connections, determine the two network devices in a  
transmission path that are separated by the greatest number of segments.  
Define a segment path between the network devices by labeling the  
cable connection to the first device segment 1and numbering each  
segment in the path to the last network device, up to segment n(n =  
total number of segments 5). Verify that no segment path in the entire  
collision domain contains more than n 5 segments.
