Figure 3.12 Internal Switch
The number of network interfaces Ethernet, E1 and xDSL depends on the model of the device.
A 4-port Ethernet switch is embedded in the printed board of LTUs. In the software of S-Access
Etherlink_II devices of the V9 type, the group of physical ports ETH1, ETH2, ETH3 and ETH4 is
combined logically into one LAN port (VLAN tag, TRUNK/ACCESS, QoS, priority queues of
Ethernet packets), the configuration being performed simultaneously for physical Ethernet ports.
The choice of the interface (DSL, or E1), which will be mapped to the corresponding WAN
interface, is performed by the <PAYLOAD> и <WANTS> commands.
The DSL channel is strictly mapped on WA1 for single-channel modems, while the E1 interface
is strictly mapped on WA2 (see Figure 3.13).
