As margens Downstream e Upstream são as mesmas que as margens SNR?
Sim, eles são iguais.
Which figures do I need to look for?
Various makes of routers may name the figures slightly differently, but the important figures that you are looking for should be something similar to:
- Connection or Sync Speed or Rate
- Attenuation or Atten or Loop Loss
- SNR Margin or Noise Margin or Noise or Margin
- Details of any CRC/HEC/RS/FEC errors and Errored Seconds may also be helpful.
