Network Specifications

Table 4 provides an overview of IEEE 802.3 and 802.3u specifications for

10Base-T and 100Base-TX network configurations using shielded twisted-pair

wiring.

100Base-TX Cable

There are various grades of voice-quality and data-quality cables available.

These can appear to be similar externally, although their high-speed data

transmission characteristics are radically different.

The identification problem is made worse by some suppliers selling

voice-quality cables as data-quality cables.

If voice-quality cables are used in a 100Base-TX network system, data

movement may be slow, collision-prone or non-existent. In addition, interface

LEDs will usually indicate a valid link in such cases.

Category 5 is required cabling for use with 100Base-TX connections. Using any

other category for a 100Base-TX connection may have high error rates and may

not have the capacity to transmit data.
