Lewis, Well, it seems that I've learned the concept of bridge though let me getSo far, so good. The difference between a bridge and a router is that a router connects two separate ethernet networks of the same topology (that's redundant; it connects two _ethernet_ networks). A bridge, OTOH, connects two different topologies, thereby creating a "bridge" between them. For DSL, this typically (in the case of SDSL and ADSL) means connecting an ethernet network to an analog telephone connection (I know, I know... DSL means *digital* subscriber line...).
this straight. Working backward, the AP is the transceiver, the router is
the IP connector (for lack of better terminology) and the bridge is the
DSL modem hardware?
And when DSL is down, the bridge is capable of usingNo. You'd need either a router configured to detect the dead link (dead link detection, as it is commonly called; fancy that?) and then re-route the connection to a second routed (WAN) port, which in this case, would not be ethernet, but rather serial, to which a modem would be connected (either externally, as in the Nexland ISB100, or internally). The other alternative would be something akin to Cisco's HSRP (hot start routing protocol) where two or more separate routers are configured to act as one logical unit. One router is designated as the primary, and the others fall behind, in suit. When a dead link is detected by the primary (or the primary fails), the secondary fires up an alternate route. As the units are configured to share a single logical IP address, the clients don't know the difference, as their default gateway address hasn't changed.
an analog modem for a dial-up connection? About right?
Also, what's aAn intelligent hub. A hub merely divides bandwidth equally among all connected devices. This is the way Wi-Fi access points work, too. It is analogous to a lawn hose splitter, where equal amounts of water flow through each outlet of the splitter. A switch, OTOH, manages bandwidth much more efficiently, by taking advantage of the packetization of data and rapidly switching on and off the different connections. This gives the appearance to the devices that each one has a dedicated connection with (practically) a full pump. Pretty slick.
switch?
BTW, I've now been able to connect my IBM UltraPort Camera II (USB) to theI've thought about getting an UltraPort camera, but I didn't think there were any OS/2 drivers available (there's a familiar song, huh?).
TP and look forward to video conferencing. Is anyone doing this over their
wireless DSL connection yet? Any success? Pros and Cons? Gotchas?
Suggestions for hardware?
