Neil, understanding the technologies involved, however, is fundamental to
answering your question. Given your drawing below, the "external converter"
you refer to translates to a "layer 2 device connecting Ethernet and Serial
interfaces", most likely you want to connect 10BaseT interface to V.35. This
device DOES exist - it is called a bridge.
The simplest, most readily available, and obvious implementation of the
device you seek is a Cisco 2501. But you have stated that a 2501 is not what
you want.
I get the impression that what you want is a device about the size of a
cigarette pack, with one RJ45 jack and one DB60 jack, that will perform this
bridging function on a "plug-and-play" basis. You never mentioned cost, but
I also get the impression that you'd like the price to be low, like under
$100 or something... My guess would be that it won't happen this decade...
Ever seen a gender changer? How about a serial dongle that changes the
connector end from DB9 to DB25? I think that Priscilla wanted to warn you
and others that there is no possibility of such a dongle to enable you to
plug your Cat5 cable into one side and your V.35 cable into the other and
have Ethernet to Serial communications work. It just ain't that simple. It's
gonna take circuitry to perform a bridging fuction.
If you understand that, fine. Looking at some of the other replies to your
post it seems clear that others do not, and a quick read of the Cisco link
Priscilla offers should clear things up for them.
Now - if you can contract the folks at RonCo to get cracking on that "Pocket
Bridge" you may be on to something. If you can't wait that long, there might
be another 2501 in your future - though it looks like the LanNode bridge
referenced in the link below might do the job for ya. It is a bit bigger
than a cigarrette pack, more like the size of a carton of smokes.
