Note:
When an analog link is completed, the Adaptive Equalizer (AEQ) is frozen. The
noise level is increased without making new links. These tests were conducted
using a Consultronics TCS500 Telephone Line Simulator, and a Hewlett Packard
4951B protocol analyzer/BERT tester under the following conditions:
