Module Connectors
RJ-21 Connector
The RJ-21 connectors (shown in
Figure B-14
) are used on telco modules. Each RJ-21 connector has pins
for 12 ports.
Note
The RJ-21 connector for the WS-X6624-FXS module has pins for 24 ports. See the
“RJ-21 Connector
(WS-X6624-FXS Only)” section on page B-27
.
To connect to 10/100BASE-TX RJ-21 telco interfaces, use Category 5 UTP cables with male RJ-21
connectors, as shown in
Figure B-14
. The WS-X6224-FXS analog interface module also uses an RJ-21
connector, but the pinout arrangement is different than the 10/100BASE-TX.
Figure B-14
RJ-21 Telco Interface Cable Connectors
Table B-23
lists the output signals for the RJ-21 telco connector. The receive and transmit signals are
polarized. One pin of each signal pair carries the positive (+) signal, and the other pin carries the negative
(–) signal.
Note
Table B-23
lists the
output signals
for the RJ-21 telco connector, not the
pinouts
of the cable connecting
to the module.
Warning
If the symbol of suitability with an overlaid cross appears above a port, you must not connect the
port to a public network that follows the European Union standards. Connecting the port to this type
of public network can cause severe personal injury or can damage the unit.
