MODEL 195Ea CONFIGURATION
MODES
The Model 195Ea can be configured for
multiple modes of operation without any
changes to the hardware. The following
are brief descriptions of the configuration
modes. For detailed descriptions and
suggested applications for each mode,
please refer to Chapter 4 – Example
Applications:
Access Point Modes
When the Model 195Ea is configured as an
Access Point it will provide a wireless
bridge from a hardwired Local Area
Network (LAN) to other Model 195Ea
modems in client modes. Multiple Access
Point Bridge modems can be physically
connected to the same network (LAN) or
through a radio link using the Access Point
Repeater mode to provide overlapping, seamless Ethernet communication for mobile devices. The ESTeem Model
195Ea in Access Point Bridge mode will pass all network traffic between connected devices including global network
broadcasts.
1.
Access Point Bridge Mode
The ESTeem Model 195Ea in Access Point Bridge mode will both provide wireless access to mobile clients
(Access Point) and bridge all Ethernet data connected to the Ethernet ports. The AP Bridge mode will pass all
network traffic between connected devices including global network broadcasts. See Figure 2.
2.
Access Point Router Mode
In this mode the ESTeem Model
195Ea will function as a router
between wired Ethernet networks,
connected to the 195Ea’s Ethernet
port, and the wireless network of
mobile clients and other 195Ea’s. As
in all standard router configurations,
the wireless and wired Ethernet
networks will need to be on separate
subnets. The 195Ea in Access Point
Router mode will pass network traffic
for connected devices but will block
global network broadcasts from the
wired network. This mode of
operation should be used instead of
the Access Point Bridge mode when
a separation between networks is
required or the ESTeem is
connected to larger LAN Networks
that will continuously send global
network broadcasts (Figure 3).
