1.2.5 CONNECTING THE ADSLX AND
POTS INTERFACES
The EXP212/EXP224 supports 12/24 ports ADSLx
subscribers per box. The EXP248 supports 24/48
ports ADSLx subscribers per box. There are four
RJ21 50-pin female connectors on the front panel
of the system. Two for ADSL line and two 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 POTS or LINE interface female connector
on the front panel. The other end of the cable is
generally tied to the MDF.
The following figures shows the Line/POTS port
position of the system:
