The following table shows the most commonly used Token-Ring cable. Use this
table to verify that you are using compatible Token-Ring cabling throughout your
network. The cable designation is generally stamped on the cable jacket.
NOTE Make sure that all of your cables have the same Velocity of Propagation (Vp).
Cable Type VP Impedance
Type 1 (STP) 78 150
Type 3 (UTP) level 3 60 100
Type 3 (UTP) level 4 69 100
Type 3 (UTP) level 5 78 100
