AT-1700

The identification problem is exaggerated by the fact that some

suppliers have sold purportedly data-quality cables

manufactured with voice-quality cabling.

If any voice-quality cabling is used in a 10BASE-T network

system, data movement is slow, collision-prone or non-existent.

To confuse the issue, the LINK indicator on the interface will

usually indicate a valid link in such a case.

For the foregoing reasons, it is absolutely vital that all cabling

used with the 10BASE-T adapter card connections is of level 3, 4,

5 or IBM type 1. As a rule of thumb, if a cable type is flat, it is

typically untwisted, and will cause problems. If a cable is more or

less round in section, it will typically work.
