Malicious call trace
The malicious call trace (MCT) voice recorder connects directly to the tip and ring
connections of a TN763/D auxiliary trunk circuit pack. See Figure 44. The 909A/B
universal coupler provides seizure control to the recorder.
NOTE:
There is no auxiliary trunk circuit pack for the G700 Media Gateway, so
information in this chapter does not apply to the G700 Media Gateway.
However, you can access MCT equipment connected to a port network.
