14.2.4 Principle of Clock Synchronization Data Plan

Wireless base stations have high requirements on clock precision. Clock synchronization
solutions must be planned based on types and standards of base stations.

QinQ private line services use a separate T-
CONT to distinguish the QinQ private line
services from other services.
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.)
Configure DBA bandwidth based on bandwidth
requirements of base stations.
Configure a traffic profile based on bandwidth
requirements of base stations.
Rates of upstream ports are not limited.
Rates of downstream ports are not limited.
