100Base-Tx Fast Ethernet Guidelines - Netopia Fast EtherTX-10 User Manual

30 Appendix B
100B -TX F
ASE
The following general guidelines apply to 100Base-TX Fast Ether-
net networks:
I
The maximum length of a 100Base-TX cable segment is 330
feet (100 meters).
I
The maximum number of end nodes on a 100Base-TX cable
segment is one.
I
The required cable type is 2-pair EIA/TIA Category 5 UTP.

ASE HUB CLASSIFICATIONS
The 100Base-TX specification supports two different classifica-
tions of hubs, Class I and Class II.
I
A 100Base-TX network using Class I hubs does not allow
more than one hub (repeater) between two end node devices.
If more than one Class I hub is installed on a network, then a
bridge, router, or switch is required between each of the
hubs.
I
A 100Base-TX network using Class II hubs allows two hubs to
be interconnected directly without the need for a bridge,
router, or switch. If there are more than two Class II hubs
installed on a network, then a bridge, router, or switch is
required between every two sets of hubs. Farallon's Fast
Starlet hubs are Class II hubs.
