E
EEC directive
A law enacted by the European Union for enforcement by its Common Market. The terms of such
a law have been used as a point of reference against which to compare the intentional RF
emissions of the MRO.

EIRP
The equivalent isotropically radiated power. The density of the peak power of a radio in the
direction of its greatest amount of gain. This is typically expressed in dBm, a measure relative to
power out per mW.

ESD
Electrostatic discharge, a hazard that electronic equipment such as the MRO can suffer by way of
exposure to static electricity or proximity to something that has no connection to ground.

FDD
Frequency-division duplexing, a radio indexing system whose transmit and receive signals are on
differing carrier frequencies.
differing carrier frequencies.
FRU
Field-replaceable unit, a designation connoting that the part can be removed in favor of a new one
when diagnostic exercises seem to have isolated a fault to the part. The overall implication is that,
if those exercises point to either no particular part, then the entire unit should be replaced. In the
case of the MRO, the only FRUs are the SFP port modules (see also SFPs) and the whole MRO
itself.
