Extender RF Split Upgrade
Application Note
Overview
Introduction
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 1.2 GHz
GainMaker® Line Extenders.
GainMaker® Line Extenders.
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 line extender 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.

WARNING:
Avoid electric shock. Opening or removing this equipment cover may expose
you to dangerous voltages. RF split upgrades should only be conducted on
line extenders that have been removed from the cable system, not on line
extenders actively in service.
