Layer 2
interoperatio
n between
different
enterprise
branches
ONUs are deployed in
branches of an enterprise.
The ONUs access and
converge Ethernet services of
the enterprise through FE/GE
ports and transmit the
services to the OLT. The OLT
implements Layer 2
interoperation between
different branches of the
enterprise.

DDN private
line access
a protocol converter is
deployed between an ONU
and DDN node machine to
convert DDN private line
services to E1 services. The
ONU accesses the E1
services and encapsulates the
service packets in TDM over
GEM mode and then
transmits the packets to the
OLT. The OLT decapsulates
the service packets to E1 data
and transmits the data to the
SDH network through
upstream E1/STM-1 ports,
achieving transparent
transmission of DDN
services.
SCUN+GPBC/
GPBD+TOPA
For E1 upstream
transmission, the
TOPA daughter
board is NH1A.
For STM-1
upstream
transmission, the
TOPA daughter
board is O2CE.
MA5612, MA5628
ONUs access IP PBX
services through FE/GE
ports. The OLT transparently
transmits the data to the IP
network in QinQ mode.
