BITS clock
Applies to the base
station that requires
only frequency
synchronization,
such as GSM/
WCDMA. In
addition, the OLT
must have BITS
clock input
resources.
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. The OLT must
have BITS clock
resources.
2. BITS clocks
cannot provide
independent
service clocks for
each E1 channel.
3. BITS clocks
support only
frequency
synchronization.
