ALFOplus 24GHz (North America) - Release 01.05.0x - MN.00395.E - 004 23
6.2 LINE INTERFACE CHARACTERISTICS
The line interfaces (LAN1, LAN2) are connected to an embedded Ethernet switch. Ethernet traffic is for-
warded to the radio interface through a 1 Gbps port, baseband and modem processing blocks. Network
synchronism can be acquired and provided by each Ethernet switch port (see Fig.5
).
