Applicable ONU
E1 base
station access
service (in
Native TDM
mode)
the ONU accesses TDM
services of the 2G or 3G base
station through the E1 port,
and then transmits the service
data to the GPON service
board on the OLT in the
Native TDM mode. The OLT
restores TDM signals, and
then transmits the signals to
the SDH network through the
E1 port (provided by the
NH1A daughter board) or
STM-1 port (provided by the
O2CE daughter board) on the
TOPA board. In this manner,
service access of the 2G or 3G
base station is implemented
between the ONU and the
OLT in the Native TDM
mode.

E1 base
station access
service (in
SAToP
mode)
the ONU accesses E1/T1
services of the 2G or 3G base
station through the unified
hardware port, and then
transmits the service data to
the OLT in the SAToP mode.
The OLT restores E1/T1
signals, and then transmits
the signals to the SDH
network through the E1/T1
port. In this manner, service
access of the 2G or 3G base
station is implemented
between the ONU and the
OLT in the SAToP mode.
