Requirements
Ethernet clock
Applies to the BTS
that requires only
frequency
synchronization,
such as GSM/
WCDMA. In
addition, the OLT
upstream network
has the capability of
synchronizing
Ethernet clocks.
1. Clock precision
meets the
following
requirements:
l
G.8262
features when
CKMC/
CKMD
stratum-3
clock units are
configured
l
EEC
specifications
defined in G.
8261 when no
stratum-3
clock units are
configured
2. No requirements
on delay, jitter, or
pack loss of a
PSN network
1. Ethernet clocks
require that MAN
PSN networks
have the
capability of
synchronizing
Ethernet clocks.
2. Ethernet clocks
support only
frequency
synchronization.
Boards that support
this feature:
H801X2CS,
H801GSCA,
H801GICK,
H801SPUA, and
H801SPUF
"1PPS+ToD" time
injection
Applies to the BTS
that requires time
synchronization,
such as CDMA2000/
TD-SCDMA/LTE.
When the OLT
upstream network
does not support
1588V2, 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 have
requirements on
PSN networks.
A BITS server must
be at the same place
as the OLT.
