the FXS interface. An FXO interface is a two-wire interface; the leads are called the tip (T) and the ring
(R).
You can interconnect the following voice applications with CESoPSN bundles:
•
Analog 4WE&M voice applications using the 4WE&M interface module
•
Digital voice applications using the T1/E1 interface module
Both interface modules consist of a front module and an RTM. See Figure 20 on page 21 and
Figure 21 on page 21 for the CTP2000 2W-FXS interface module.

Both modules use connector A on the RTM. For both modules, connector B and the RJ-45 connectors are
not used. See “CTP2000 FXS and FXO Interface Module Cables and Pinouts” on page 48 for connector
pinout information.
You set the signaling by using the software on both modules. You cannot reconfigure the jumper parameters.
