ABLING
Note that the module consists of four pairs of numbered RJ45 ports; you must properly connect the
CSX1200 BRI ports to the corresponding U4 S/T interface ports of each pair on the module. We
provide four 6-inch, category 5, twisted-pair cables (with RJ45 connectors) for this purpose:

1.
Using the twisted-pair cables, connect BRI port 1 to the S/T interface port labelled number 1,
BRI port 2 to S/T interface port number 2, and so on. The module then converts the S/T
interface to a U interface for each pair of ports.
BRI port 2 to S/T interface port number 2, and so on. The module then converts the S/T
interface to a U interface for each pair of ports.
2.
Next, use the category 5 straight-through interface cables (with RJ45 connectors) to link the U-
port in each pair to the service provider’s ISDN jack.

Note:
For network safety, use only 26AWG or heavier (i.e., a lower numerical value) cable for all
CSX1200 and U4 interfaces.
