Remarks
l DBA is used to
control the
upstream
bandwidth of the
ONT. DBA
profiles are
bound to
TCONTs.
Different
TCONTs are
planned for
different
bandwidth
assurance types.
l Generally, the
service with a
high priority
adopts a fixed
bandwidth or an
assured
bandwidth, and
the service with a
low priority
adopts the
maximum
bandwidth or
best effort.
l Traffic control
can be
implemented on
the BRAS, or on
the OLT or ONT
by using port rate
limitation or
using a traffic
profile to limit
the upstream and
downstream
traffic.
l Generally, in the
case of FTTH,
limit the rate on
the OLT.
