Parameter Value
DBA Type Type 3 ("Assured bandwidth+maximum
bandwidth" DBA profile. This type of DBA not
only ensures a fixed bandwidth for users but also
enables users to preempt a certain amount of
bandwidth, but the total bandwidth cannot
exceed the maximum bandwidth.)
DBA bandwidth Plan the bandwidth according to users'
requirements.
Downstream traffic
profile
Configure the profile according to users'
bandwidth requirements.
ONU Upstream port rate
limit
Rates of upstream ports are not limited.
Downstream port
rate limit
Rates of downstream ports are not limited.
Enterprise DDN Private Line Access
In this scenario, ONUs access services from the DDN through E1 lines. Therefore, the QoS
policies are mainly planned for traffic on PON lines.
Parameter Value Remarks
T-CONT It is recommended that the number
of T-CONTs do not exceed 3. The
T-CONT ID ranges from 1 to 3.
It is recommended that all E1 lines
of the same ONU use the same T-
CONT.
DBA type Fixed bandwidth and minimum
delay
The DBA must be configured
properly to achieve low delay, low
jitter, and zero packet loss so that
the quality of the DDN private line
service can be ensured.
DBA bandwidth Nx7232 kbit/s is recommended. (N
is the number of E1 lines.)
It is recommended that the T-
CONT ID be 1, 2, or 3 and all E1
lines of the same ONU use the
same T-CONT. This setting can
leverage bandwidth resources.
Each E1 line requires only 5440
kbit/s.
