75-Ohm In-Line Coaxial Attenuator (Optional)

75-Ohm In-Line Coaxial Attenuator (Optional)
A 75-ohm in-line coaxial attenuator may be required to tune the signal between the 6E3 line card and
the far-end equipment if the line card is experiencing line code violations (LCVs). LCVs occur when the
far-end equipment transmit signal saturates the front-end receiver of the 6E3 line card.
Cisco offers an attenuator kit (ATTEN-KIT-PA=) that contains five attenuators with fixed values ranging
from 3 dB to 20 dB. For more information on the attenuator kit, go to Installing the 75-Ohm In-line
