2.3 TYPICAL CONFIGURATIONS

Physical connectivity to a Token Ring network is provided by either shielded twisted pair (STP) or unshielded twisted pair (UTP) cabling that connects the Token Ring module to a Hub. Each Token Ring switch module provides only one kind of connector, either four DB9 connectors for STP cabling or four RJ45 connectors for UTP cabling.

2.4CONNECTING THE TOKEN RING MODULE TO A HUB

It is not possible to attach workstations directly to the ATX Token Ring port. Either an active or a passive Hub must be used. A passive Hub contains fairly simple electronics (principally relays) which form a self-healing electrical ring. An active Hub contains more sophisticated ring-maintenance circuitry and may be manageable.

2.4.1Unshielded Twisted Pair

When using Unshielded Twisted Pair cabling in a Token Ring environment, make sure that it conforms to the specifications in Table 2-1 (this assumes patch cables that are no longer than 8 feet or 2.4 meters):
