2.2.3 Network Controllers
Network controllers connect your system to an Ethernet network. With
a network connection
and appropriate DECnet software, you can use all
network services.
NOTE: The MicroVAX 3400 and VAXserver 3400 systems include an
Ethernet controller on the CPU module. One of the following controllers
is only necessary
if the system requires a second Ethernet connection.
2.2.3.1 DESQA Ethernet Controller
The DESQA network controller provides a high-speed asynchronous
connection between a Q-bus system and a Local Area Network (LAN) based
on
Ethernet or IEEE 802.3. The DESQA supports either standard or
Thin Wire Ethernet cabling.
