Networking Requirements
As shown in
from BITS servers. NodeB 2 does not support 1588v2 but supports frequency synchronization
through the synchronous Ethernet clock. NodeB 1 and NodeB 3 support 1588v2. Frequency
synchronization can be achieved between wireless NodeBs and the bearer network devices, and
time synchronization can be achieved between 1588v2-aware NodeBs and the bearer network
devices.
All devices of the bearer network support 1588v2 so that they can be configured as BCs to
transmit clock information. In addition, CE2 can send E1 signals carrying frequency information
to non-1588v2-aware NodeB 2 for restoring frequency synchronization.
