Step 2: Connecting the ADSL LINE and PHONE interfaces
The IDL-2402 supports 24 ports ADSL subscribers per box. There are two RJ21 50-pin
female connectors on the front panel of the system. One for ADSL line and one for POTS
interface.
To connect the subscriber lines, use cables with the RJ21 50-pin male connectors. When
installing, just plug the end of a cable with connector into the LINE and PHONE interface
female connector on the front panel. The other end of the cable is generally tied to the
MDF (Main Distribution Frame).
The pin assignment of LINE/PHONE interface is illustrated below (the numbers in the
connector figures below represent PIN numbers):
