Note: This configuration is the least reliable due to lockup problems
inherent in Smart Modems from power spikes and noisy lines. To
increase the reliability on this configuration, use a constant power
source when powering the modems. Also, verify that TIE lines meet data
grade specifications. Nortel takes no responsibility for ISL D-Channel
outages due to modem lockup.
