    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.

  • Page 9: Access Point Repeater

    Ethernet network to devices on the wireless network will be rejected similar to the operation of a “firewall”. The 195Ea will hide all the IP addresses connected on the wireless link. You should use this mode of operation if Model 195Ea is connected directly to the Internet with a static IP address (DSL, T1, etc.) and you want the wireless clients to access the information through the Model 195Ea (Figure 3).

    Device, the Model 195Ea will provide wireless mobile access to that device through a canopy of Access Points. The 195Ea will seamless roam under the radio canopy of Access Point and can provide greatly increased range for mobile Ethernet devices such as vehicles, forklifts, cranes, etc (Figures 1-3).

    The following steps should be completed to begin configuration of the ESTeem Model 195Ea: Connect the antenna to the antenna connector on the ESTeem Model 195Ea (Figure 3). For a single antenna use Antenna Port A and connect both if using dual antennas.

  • Page 14: Chapter 3 - Example Applications

    The most commonly used mode of operation with the ESTeem Model 195Ea is the Ethernet bridge mode. The Ethernet bridge mode will connect two or more ESTeem 195Ea’s while passing all network traffic that arrives in both the wireless and connected Ethernet ports; including all global network traffic (Figure 1). This mode will work in most wireless applications of the 195Ea to wirelessly connect two or more remote Ethernet devices or networks.

  • Page 16: Router Modes

    Router Modes (AP Router and AP Masquerade) The ESTeem 195Ea can be configured as a network router or network firewall between the Ethernet LAN connection and the wireless network of remote locations. The router modes are used to limit the network traffic from a busy Ethernet network connection to only those specific IP address used on the wireless network (see Figure 4).

    Mobile Client Modes (EtherStation, Station Router or Station Masquerade) The ESTeem 195Ea can also be configured to function as a mobile client. The client modes will allow the 195Ea to seamlessly roam between other 195Ea configured as Access Points (AP). These Access Points can be ESTeem 195Ea’s configured in one of the three Access Point modes (AP Bridge, AP Router or AP Masquerade –...

  • Page 37: Configuring Time Server

    UTILITIES & FEATURES CONFIGURING TIME SERVER Enabling NTP time synchronization services on the ESTeem 195Ea will allow usage of time services from upstream services to keep the time on the system accurate. To allow time synchronization, the Model 195Ea must be configured with the NTP Daemon enabled and the appropriate IP address of the upstream network NTP server.
  • Page 38 CHAPTER 4 UTILITIES & FEATURES 3. The NTP daemon is enabled by selecting YES for NTP ENABLE (Figure 12). When enabled, the NTP daemon will use time services from upstream services to keep the time on this system accurate. 4. Next, the NTP SERVICE ENABLE should be configured to “YES,” if you want to allow the system to provide NTP service for clients wishing time synchronization (Figure 12).

  • Page 39: Vlan Operation

    Virtual LAN (VLAN) systems are rapidly becoming the desired configuration on larger Ethernet networks. The ESTeem 195Ea software will allow the Ethernet modems to transparently pass the VLAN packets for these networks. The 195Ea currently can not be used as a VLAN switch, but will pass VLAN tagged Ethernet packets through the wireless bridge.

  • Page 40: Igmp Snooping

    Ethernet Bridge and mobile devices communicating to these fixed points. The fixed point Ethernet bridge communication in the 195Ea is through Repeater Peer links, while the mobile communication is from the Client modes (EtherStation, Station Router and Station Masquerade) to the Access Points (Fixed Locations) in the network.
  • Page 41 UTILITIES & FEATURES When the ESTeem 195Ea is configured as a repeater peer, all multicast traffic is “wrapped” in a Unicast frame and sent to all other repeater peers. (Figure 14) This operation allows the ESTeem network to receive an acknowledge packet and retransmit the data if the packet is lost during transmission.
  • Page 42 Ethernet Bridge Mode (Repeater Peers) With IGMP Snooping When the ESTeem 195Ea is configured as a repeater peer, IGMP Snooping is enabled and the network supports IGMP protocol, the 195Ea will begin to identify the connected Ethernet devices using Multicast transmissions and report this information to the network.
  • Page 43 UTILITIES & FEATURES Client Modes When the ESTeem 195Ea is configured as a mobile client (EtherStation, Station Router or Station Masquerade), there are two configurations that will increase the reliability of Multicast traffic. The first phase is encapsulation of the multicast packets, as described in the Repeater Peer, and the second is IGMP Snooping if the network will support the protocol.

  • Page 59 SERIAL APPLICATIONS Mode of Operation There are two distinct modes of operation for the serial port in the 195Ea. The Redirector mode will provide two-way serial communication between two or more serial devices, while the Terminal Server mode will allow serial communication to a specific remote site by connecting through telnet or SSH.
  • Page 60 If you are using multiple ESTeem repeater links to send the serial data to remote locations, the value for the maximum bridge link needs to be increased to a number greater than the longest repeater chain. For example, if you are using four repeater (peer) links to send the serial data between two or more sites the number will need to be five (5) or greater (Figure 4).

  • Page 61: Esteem Mesh Network

    When programmed in any of the three Access Point (AP) Repeater Modes, the Model 195Ea will create a wireless network with other Model 195Ea units in radio range that are programmed in the AP Repeater Peer table during setup. This feature adds the increased functionality of repeaters to the typical Ethernet Bridge configuration.

  • Page 62: Rapid Spanning Tree Protocol (Rstp)

    This RSTP functions the same as standard Spanning Tree Protocol (STP) listed below, but the network recovery is three times faster. If the 195Ea is used in a network that has any older STP only modems, the entire network will be STP.
  • Page 63 SPANNING TREE PROTOCOL The ESTeem Model 195Ea uses standard Ethernet Rapid Spanning Tree Protocol (RSTP) to determine the radio routing structure of the wireless network. The primary purpose of RSTP is to make sure that “network loops” are not created. A network loop is having two communication paths to the same destination where the remote device would receive the same data multiple times.

  • Page 64: Root Bridge

    If more than one communication path to the Root Bridge is found, the 195Ea must determine which route to take based upon the lowest Path Length. The default path length to all links in the 195Ea network is 1. If the Path Lengths are equal then the lowest MAC address will determine the priority route.

  • Page 65: Redundant Backup

    Model 195Ea’s are installed at the same location (Figure 7). If two Model 195Ea’s are connected to the same switch, one of the Model 195Ea’s will be Blocked when the Spanning Tree Protocol is completed.
