– 9.9 to – 1.0 dBm
Maximum average receive power for damage
0 dBm
Maximum receiver sensitivity in OMA

The stressed sensitivity values are for system level BER measurements, which include the effects of
clock and data recovery (CDR) circuits. Avaya recommends that you allocate at least 0.4 dB
additional margin if you make component level measurements without the effect of CDR circuits.
