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 21 on page 21 for the CTP2000 2W-FXS interface module.
