Product Description
The 75-ohm in-line coaxial attenuator is purchased in a kit (ATTEN-KIT-PA=) containing five
attenuators with fixed values ranging from 3-dB to 20-dB. The kit was designed for use with Cisco T3
port adapters when the port adapter is found to be experiencing line code violations (LCVs). LCVs occur
when the far end equipment transmit signal saturates the front end receiver of the T3 port adapter. The
attenuators are used to reduce the signal strength. Each kit contains a 3-dB, 6-dB, 10-dB, 15-dB, and
20-dB attenuator with standard BNC connectors (see
