Carrier-in-Carrier Summary

Comtech EF Data's DoubleTalk Carrier‐in‐Carrier can provide significant savings in operational
expenses. The following considerations must be taken into account when evaluating CnC:
•
CnC can only be used for full duplex links where the transmitting earth station is able to
receive itself.
•
CnC can be used in both bandwidth‐limited and power‐limited situations.
•
The maximum savings is generally achieved when the original link is symmetric in data
rate.
