Cisco Multimedia Line Equalizer/Reverse 
Conditioner 1.25 GHz 

The Cisco

®

 1.25 GHz Multimedia Line Equalizer/Reverse Conditioner (LEQ/RC), 

shown in Figure 1, improves network performance on both the forward and reverse 
paths in a coaxial transmission system. 

In the forward path, the fixed forward equalizer offsets undesirable down-tilt associated with cumulative cable and 

passive losses, allowing tap port RF levels to be maintained within desired design limits, even at taps located near 

the ends of lines. 

In the reverse path, plug-in attenuation allows RF levels to be conditioned for optimal performance of critical 

reverse path services. By selectively adding reverse attenuation at Cisco Multimedia LEQ/RC locations, the range 

of RF levels transmitted from closed-loop customer premises equipment in a given service area can be narrowed 

considerably. 

With greater percentages of network devices transmitting in the upper end of their RF transmit ranges, 

improvements in carrier-to-ingress and carrier-to-noise performance can be realized.

Features 

● 

Fixed 9 dB or 11 dB forward equalizers 

● 

Plug-in attenuator location for reverse-path optimization 

● 

Connection beam noninterruptible AC and RF bypass (Figure 2) that optimizes network availability during 

maintenance periods 

● 

Equalizer in and out bypass, which allows reverse conditioning deployment network locations where forward 

equalization is not desired
