E1/STM-1/T1 line
clock
Applies to the BTS
that requires only
frequency
synchronization,
such as GSM/
WCDMA. In
addition, the OLT
can directly connect
to an SDH network.
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. E1/STM-1 line
clocks are all
obtained from
physical line
clocks and they
have the best
performance in
terms of stability
and reliability.
1. In E1/STM-1
upstream
transmission, the
OLT must be in
the same office as
SDH equipment.
2. E1/STM-1 line
clocks support
only frequency
synchronization.
Boards that support
this feature:
l STM-1 line
clock:
H801TOPA
(configured with
the H801CSSA
daughter board)
or H801TOPA
(configured with
the H801O2CE
daughter board).
l E1 line clock:
H801TOPA
(configured with
the H801NH1A
daughter board),
H801TOPA
(configured with
the H801EH1A
daughter board)
or H802EDTB.
l T1 line clock:
H802EDTB
