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.
