3. Application and Services
MSAP2000 Technical Manual V3.0 3-9
Optical Gigabit
Ethernet
MSAP2000 supports Gigabit Ethernet (GbE) optic transmission.
The AAM Module can directly connect the packet to the GbE via
an IP backplane bus; it is then directly connected to the Router,
or the Layer 3 Switch of the telecommunications server room,
via optic fiber transmission.
3.8. Ethernet over SDH Services
Because SDH was formerly widely used as a basis for network
construction, there is a surplus of unused SDH bandwidths.
MSAP2000 transmits Ethernet packets by SDH, using ITU-T
G.7041 transmission modes. This solution can allow network
Service Providers to utilize existing network bases, for Ethernet
service provision.
As shown in the following diagram, MSAP2000 can provide
each individual subscriber with simultaneous phone and
broadband access services.
