DSL Network Interface Cable
The 50-pin RJ21X Telco connectors at the rear of
the BitStorm 4800 provide the 2-wire loop interface
from each DSL port to the demarcation point. (The
Canadian designation for this connector is
CA21A.) There is one connector or two connectors
depending on whether the BitStorm 4800 supports
24 or 48 DSL ports, respectively.
Table A-3, DSL Connector Pinouts
, lists the pin
assignments for each of these interfaces. Note that
Pins 25 and 50 are not
used.
