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
