THE CSX1200-U4-MOD

The CSX1200-U4-MOD is a U-interface option card for the CSX1200 family. This module is only relevant for applications in North America, since North American telephone companies typically do not provide the needed U-interface conversion. The CSX1200-U4-MOD performs the function of an external NT1, and is available for the BRI (1201, 1204) CSX1200 models. Below, we show the module installed in a CSX1223.

CSX1223 with CSX1200-U4-MOD

The module consists of four pairs of numbered RJ45 ports. To activate the installed module, you must properly connect the CSX1200 BRI ports to the corresponding S/T interface ports on the U4 module. This process, along with complete installation instructions, is detailed in the Hardware Installation chapter.

This module is also equipped with four NT1 Status LEDs to indicate the status of each of the ports. Refer to the LED Indicators chapter for further information.
