Define the minimum and maximum values from the available range.
Minimum Data Rate - Minimal rate of data (per bearer channel), below this
rate the modem is considered as failed. The minimum-bitrate parameter
specifies the fixed-rate component of the service. This could be used to
ensure that sufficient bandwidth is available for minimum SLA and any
traffic engineered service (i.e. VoIP or IPTV) that requires a fixed
bandwidth allocation. The Maximum Rate parameter is set to the total
bandwidth required for traffic engineered services in addition to best-effort
services such as Internet Access.
Allowed Maximum Data Rate Downstream/Upstream – specifies maximal
data rate (cannot be exceeded).
Data Rate = Line Rate - Data Protection & EOC Overhead
NOTE: Maximum Rate is used as the required rate in case that "Force
Rate" is selected in SNR Margin Profile (see SNR Margin (on page 6-24)).
DS to US preferred ratio objective. The DS/US Ratio may have impact on
modem’s final DS and US rates in very short loops and in Interleaved or
Retransmission modes. The Preferred Ratio may impact modem’s rate in
these cases since modem’s rates are limited by internal resources
limitations and not by link’s capacity (e.g. modem’s memory cannot serve
all possible BW).
Parameter default is 4:1 (objective for DS rate four times larger than US
rate).
