DOCSIS Pre-Equalization: Vastly Powerful, Often Undervalued
You probably already know that by adding a simple, one-line command in the CMTS you can see an immediate 5 to 10 dB improvement upstream MER (SNR). It’s like a magic pill that eliminates the pain that would normally be caused by impairments in your outside plan an the subscriber’s home.
Pre-equalization can mask the symptoms of underlying problems. Impairments can grow and get worse over time, and you won’t know where, how many, or how they are until service is affected. Pre-equalization data can also be used to track down impairments and directly pinpoint their location – before they impact subscribers. The quality of your service immediately improves PLUS you can reduce operational costs and avoid future outages.
