CAUTION – NETWORK MALFUNCTION
Using the modem’s loopback capabilities with the Ethernet data interface can
cause undesirable network loops. Before you do any data test with an Ethernet
interface, make sure to use two modems connected back-to-back. If you use one
modem and a loopback, it can cause unwanted results.
To lock up the modem:
• Enter IF Loopback Enable in the Test Menu
- or -
• Connect a Loopback Cable from TX port to RX port
