Connecting the iDSL ports
The remote (CPE) iDSL modems are connected to the T-DAC via the RJ-21X cable (see figure 12 ).
Figure 12. RJ-21X connector
1. Connect the RJ-21X connector of the cable into the 50-pin RJ-21X receptacle on the rear of the 3196RC.
2. The other end of the cable has 25 non-terminated twisted-pairs for connection to punch-down blocks.
Only 16 of the 25 pairs (see table 5 ) will be used since there are 16 iDSL modem connections, each requir-
ing one twisted pair. Select the twisted-pairs which will be used for active iDSL modem connections and
terminate each pair on the punch-down blocks.
