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.
