Receiver Overload*
* Typical values for nonprotected systems measured at the antenna port of the
Antenna Coupling Unit (ACU).
Dispersive Fade Margin (DFM)
*Typical values for nonprotected systems measured at the antenna port of the ACU.
Signal Acquisition Time
The system must re-establish customer traffic within 60 ms of a signal
interruption. Typical acquisition time is 60 ms for the majority of radios; the
exceptions are the 16T high gain radio with an acquisition time of 130 ms and
the 28 T high gain radio with an acquisition time of 100 ms.
For RF signal failures lasting greater than 1 minute, the system must re-
establish customer traffic within 250 ms of restoration of the RF signal.
Auto-DADE
The main and space-diversity receiver signal delays are automatically equalized
up to a diversity antenna spacing of 150 feet.
