High Speed Data
Downstream (Best Effort)
Priority 1 is often used for downstream high speed data. It is recommended that
the priority set is lower than DS Voice and Video Signaling Traffic and higher than
the Default HSD and DSG Tunnel Data.
Default HSD and DSG
Tunnel Data
Priority 0 is the default priority applied to high speed data and DSG Tunnel data,
unless otherwise specified via a modem config file (for HSD) or via SCN (for DSG).
Overload Conditions
ARRIS recommends the following for adjusting SfMinReservedRate (tmin) and SfMaxTrafficRate (tmax) as shown in the
table below whenever there is a desire to maintain toll grade performance under data overload conditions:

Upstream Voice and Video
Signaling Traffic
ARRIS strongly recommends that settings are considered to ensure that sufficient
opportunities are given for data to be transmitted on these flows. This is especially critical if
there is a desire to maintain toll grade performance under high speed data overload conditions.
Values should be selected based on your individual set up and determined by the type of
signaling and number of lines.

Leaving HSD at the tmin default of 0k reinforces the priority for polling opportunities given to
the applications listed above.
