Cable Distances

1-14
Avaya recommends the following cable distance guidelines, which
are based on IEEE 802.3z standard.
* Note: Tables 1-2 through 1-4 describe the maximum link
distances for the Gigabit, 100Mb, and 10/100 Mb links.
When building half-duplex networks using Ethernet
repeaters, you must also consider maximum network
diameter, which is not discussed in this document
