Cisco 7304 6-Port Clear Channel E3 Line Card Installation and Configuration

OL-5061-01

Chapter 2 Preparing for Installation

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

Coaxial Attenuator at the following URL:
