End-to-end 1588v2
clock
Applies to the BTS
that requires time
synchronization,
such as CDMA2000/
TD-SCDMA/LTE.
When the OLT
upstream network
supports 1588V2 hop
by hop, this solution
is recommended.
1. This solution
supports time
synchronization
and frequency
synchronization
and provides
high-precision
time. The clock
quality meets G.
813 and G.8262
specifications.
2. This solution
does not require a
1588V2 server on
the OLT.
The upstream
network of the OLT
should support
1588V2 hop by hop.
14.3.2 Configuring BITS Clock Synchronization
The OLT receives the clock through the BITS and transmits the clock to the ONU through the
PON line and then downstream to the base station, implementing clock synchronization of the
entire network.
Application Context
As shown in Figure 14-2, the OLT receives the clock from the BITS and the clock share the
same clock source with the BSC/RNC. Then the OLT transmits the clock to the ONU through
the PON line clock. After recovering the clock, the ONU transmits the clock to the base station
through the E1 or FE/GE port.
