Upstream
Burst Profiles
The upstream burst profiles are displayed for informational
and debug purposes. The upstream burst profiles use the
same FEC code types and entry and exit thresholds
defined for the downstream burst profiles.
ACM Note:
The OFDM and GMSK ACM methodology uses two criteria for changing modulations.
It is uses the average CINR/SNR value for the connection and the number of FECs. The
number of FECs represents the largest number of FECs in any symbol in the given burst.
ACM requires that only one threshold is met to cause the modulation to switch to a more
robust modulation and it requires that both CINR and FEC thresholds be met to move to a
less robust modulation.
3.6.4.1. ADD ENTRY Downstream Burst Profile Example
The user can add a burst profile entry by selecting the ADD ENTRY button within the
Downstream Burst Profile section of the Profile Config page. The user selects the FEC code
from the pull down menu and selects the ADD button to the right of the entry. The new burst
profile distributes through the network as needed. Each burst profile added gets populated with
the default CINR and FEC thresholds. The user can change those values by modifying the burst
profile.
