(PDV or Path Delay Value) in diameter between any two nodes. Nodes in a collision domain
are connected by means of a repeater or repeaters such that no bridging or switching devices
are present between any two nodes in the cluster. A Magnum 14E has a PDV of about eighty
Bit Times (20 BT), and this value must be included in the overall collision domain diameter
PDV calculations as applicable for the placement of the 14E in the topology of the collision
domain.
Collision Domain Diameter
The Collision Domain Diameter is the length of the longest path between any two
devices in a single collision domain. Regardless of the actual network topology, the Collision
Domain Diameter must be less than 512 BT (Bit Times). Bit Times are related to media type
as shown in Table 3.2.2a.
