14.2.3 Principle of QoS Data Plan
QoS planning for the base station access service is end-to-end. QoS policies include traffic
classification, marking and scheduling, traffic monitoring, and DBA policies. QoS policies for
different scenarios are different. This topic provides QoS policies in the following scenarios.
E1 Base Station Access Service (in Native TDM Mode)
In this scenario, ONUs access services 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 E1 base station
access 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.
E1/T1 Base Station Access Service (in GPON SAToP Mode)
In this scenario, ONUs access services through E1/T1 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 T1 base station
access service can be ensured.
