No. An EthIR Beam receives infrared frames from an infrared device and delivers these to the EthIR Switch. The EthIR Switch then translates these infrared frames to Ethernet frames (and vice-versa) forwarding and receiving frames to and from an Ethernet network. An Ethernet hub cannot translate infrared frames. That is the purpose of the EthIR Switch.

A switch has chips to store MAC addresses of the connected clients. Hubs do not. Therefore a switch can send packets directly to the intended computer based upon the header of the packets. Hub is different, when hub receives packets, it will broadcast packets to all the clients that are connected and that costs traffic. A switch is more efficient than a hub.

Ethernet hubs can be purchased at your local computer store. AT&T does not provide installation support for Ethernet hubs.

No, because Ethernet switches and hubs need Ethernet data. They would also add a lot of latency (or delay) to a Pro16 system. For parallel (or "star") connections, use the A-16D or A-16D Pro A-Net Distributor. Links:

A switching hub can be considered to represent a multiple-port bridge, with a complicated internal bus that allows full cross-point switching. Such a hub has low latency packet delay and allow several conversations simultaneously. It has larger bandwidth than hubs.

No. USB is designed to have two types of devices - a host (like a PC or Mac) can talk to and control other devices, while those other devices can't talk to each other. USB ethernet adaptors are designed to plug into computers, while the USB connector on the Toppy is the same sort as you'd find on a printer, or an external disk drive - in other words, it simply doesn't provide the functions necessary to link to anything like an ethernet adaptor.

Yes. SELECT customers may have up to four computers connected simultaneously. However, CLASSIC customers may only have one computer connected to the network at a time. Yes, with Choice OnLine you can surf the Net and simultaneously make phone calls or watch TV. To use a fax machine or dial-up modem while surfing the Net, you must have a normal phone line available. Your computer will not allow you to use our Choice OnLine service and dial-up to another Internet service simultaneously.

Yes- The phone should work properly when plugged into a USB hub. If experiencing problems with a vPhone using a USB hub, plug the vPhone directly into the computers USB port.

No. An EthIR Beam provides infrared connectivity for only ONE device at a time. . Usually the laptop or PDA tries to ”discover‘ an IR device, EthIR LAN in this case. If more then one PDAs are discovering at the same time, it will be the first one that discovers the EthIR LAN that wins the IR connection. Once an IR connection is established, both the PDA and EthIR LAN change to a higher baud rate to communicate.

That is not the proper way to connect a network printer to the network. A network printer must be hardwired to an existing network and accessible as a shared resource. A notebook or device must then be told of the shared device's existence. As with an Ethernet network connection, an infrared network connection merely provides a vehicle for the transmission of data to and from the computer device that is connected to the network except it does so wirelessly.

Usually a IrDA digital camera expected to communicate to a computer and uses a protocol other than TCP/IP/PPP. Unless the camera supports TCP/IP/PPP, it would not be able to connect to EthIR LAN and upload digital pictures.

If the device is a Windows 95/98 notebook or Apple Macintosh Powerbook then, Yes. Once the device detects an interruption in infrared network connectivity it continuously sends out a signal searching for an infrared access point. When it is found and the access point 'discovers' the device, network connectivity is restored. If the device is a Windows CE or Palm Pilot then, No.

Harrington, Anderson/Langdon, University, or Seward you will be plugging in your ethernet cable into a hub. A hub is a small box which takes one data port's connection and splits it into a larger set of data ports. Typically the hub will have three ports to plug into, but some rooms have hubs with more ports, depending on the number of room occupants. Todd/Phibbs, Trimble, Smith, Regester, or Schiff you will plug directly into the data jack on the wall.

No. The uplink of EthIR LAN is either 10BaseT or 10/100BaseT. It works seamless alongside existing networking devices.

The RJ45 connectors on the ES208/216 multiport EthIR Switch are designed to connect to either an EthIR Beam or a computer‘s Ethernet card. It cannot connect to the uplink of another EthIR LAN device or an Ethernet hub.

The router allows you to make a connection between your network and ADSL, so that more than one computer in your LAN can access the Internet. Certain models may give you further options such as security (firewall). A hub is the point of connection for the router and the computer to connect to the network. A switch acts like a hub but allocates an independent bandwidth to each user. This means the data transfer speed will not be decreased by additional users.

The final piece you need to put your network design together is a hub. It is used to gather groups of PCs together at a central location. The switch is actually a higher-performance alternative to a hub.

The HP Advancestack 100Base-T Hub-8txe and the ProCurve Networking by HP 100Base-T Hub 8 can only be directly connected to another Class II 100Base-T hub or to a switch. To connect them to a 10Base-T hub, either use a switch in between, or connect them to the ProCurve Networking by HP 10/100 Hub 12 or 12m or ProCurve Networking by HP 10/100 Hub 24 or 24m which are both Class II hubs that autosense the speed of each port to be either 10Mbps or 100Mbps.

Only the computer which has been registered with ResNet will be able to access the network outside your room. The remaining computers will not be able to communicate with resources outside your residence hall. Using a hub or switch can potentially cause your port to stop responding to all traffic.

Any electronics store that sells computers will sell hubs, switches, and routers. Best Buy, CompUSA, Circuit City, Radio Shack, Fry's - any of these is fine. If you go in and ask for a "networking hub", a "networking switch", or a "cable/DSL router", the pimply-faced saleskid will show you where they are. (I was a pimply-faced saleskid once, so I'm allowed to joke.)
