Back-to-back connection

In telecommunication, the term back-to-back connection has the following meanings:

1. A direct connection between the output of a transmitting device and the input of an associated receiving device.

Note: When used for equipment measurements or testing purposes, such a back-to-back connection eliminates the effects of the transmission channel or medium. 2 . A direct connection between the output of a receiving device and the input to a transmitting device.

Note: The term "direct," as used in both definitions, may be construed as permitting a passive device[?] such as a pad[?] (attenuator) to accommodate power level constraints.
