Cisco Cisco 1 GHz GainMaker Amplifier Guía De Instalación

 

 

GainMaker System Amplifier RF Split 
Upgrade Application Note 

As cable operators experience an exponential rise in the requirements for more 

reverse path bandwidth due to the popularity of advanced, on-demand services 

from an increasing number of subscribers, operators need an upgrade path for 

deployed equipment to overcome this operational challenge. 

 

This application note describes the RF split upgrade procedure for 1 GHz 

GainMaker® System Amplifier. 
You will note that the final instruction in the split change process calls for the 

verification of forward and reverse signal for each port.  This verification is 

included to ensure that all component replacements with respect to the split 

upgrade were performed correctly and to ensure that all replacement components 

perform as specified.  Making this type of significant product change in the field 

rather than in a test environment would likely cause additional network 

downtime as troubleshooting any sort of issue associated with the upgrade could 

be quite time consuming.  
While our amplifier products would generally perform acceptably without this 

verification, we recommend this extra step to ensure that our products meet 

customer expectations immediately upon placement into service. 
Should you need assistance with your upgrade, contact Cisco for support.
