Please log in for more thread options switch and a Linksys Broadband Router with 2 Phone Ports. Complete with voltage adapters for each. They were wrapped together and appear to be a matched set, but I don't understand this combination. Anyone tell me how these would have worked together? Or maybe they weren't meant to work together? I also don't understand the distinction between a "Broadband Router" and an "Ethernet Cable/DSL Router." Further, I don't understand either why a router requires a telephone connection. My friend's DSL modem has a telephone connection. I've never seen a router or a switch with one. Thanks -GECKO | ||||||||||||||||

Please log in for more thread options You could get a very precise answer, if you provided model numbers for the two boxes. :-) If I was forced to guess, I'd say it was something like this. WAN LAN ADSL/Cable ---------- VOIP_Box ----------- Router/Switch ------- Computer Modem | | +-------- Computer | | +--------- Computer RJ-11 RJ-11 +---------- Computer Phone Phone #1 #2 Some early VOIP boxes, liked to strip off the VOIP packets from the Ethernet, before hitting the Router/Switch. The reason for this has something to do with the port numbers used by VOIP. VOIP is a complicated protocol, with separate port numbers for Call Control and for Data Transport. If the VOIP box was put *after* a box with NAT (address translation), then punching holes (port forwarding) for the necessary ports becomes a painful thing. http://en.wikipedia.org/wiki/Voip Your "box with the phone jacks", might look like this. http://en.wikipedia.org/wiki/Image:VoIP_analog_telephone_adapter_diagram.png Paul | ||||||||||||||||

The one with phone ports might be one of Linksys' old HPNA ones. Posting

The datasheet (first doc) says the VOIP is SIP V2 compliant, whatever that means. ftp://ftp.linksys.com/datasheet/rt31p2_ds.pdf ftp://ftp.linksys.com/pdf/rt31p2_ug.pdf So it looks like the RT31P2 is enough to use some computers and have two phones via VOIP, all by itself. The RT31P2 might be suited to a small business, bringing VOIP analog phone connections, and some data connections for three computers. There were a number of versions of BEFSR41, some more successful than others. Some were apparently crap. One WAN port and four LAN ports. I had an early one, which required regular resetting by toggling the power. The last firmware I installed in it, would eventually forget how to do DNS after a while, which was the last straw. I replaced it, and the replacement from another firm, never gives me trouble. The replacement was on sale (clearout), and I got it for about 1/10th the price of the BEFSR41. ftp://ftp.linksys.com/datasheet/befsr41v3_ds.pdf ftp://ftp.linksys.com/pdf/befsr11_befsr41ug.pdf You could hook them together, as shown in my original answer, but I really wouldn't bother, remembering how well the BEFSR41 works. Here's hoping the RT31P2 is a better design. Paul | ||||||||||||||||
