ISDN Router Question

[Palpatine]

Do ISDN Routers have the ISDN modem built into them? If not, why are they so much more expensive than a DSL/Cable router?

Thanks,

Palpatine.

Give me an example of an ISDN router that has the built-in modem. Do any of the DLink or Netgear ISDN routers have the built-in modem?

Thanks,

Palpatine.

ISDN signal is already digital, why would they (some manufacturers) call it modem?

An ISDN modem is typically a device that hooks into your PC's serial port. You can then use it just like an analog modem and configure a DUN profile. If you have an ISDN router, then you have more options. The PPP is done from the router and is transparent to your PC, which is connected to the router via ethernet. ISDN routers and ISDN modems give you the same bandwidth, up to 128Kbps, but the ISDN modem introduces quite a bit of latency. An ISDN router gives you about 30msec latency to the NAS your are dialing into, while an ISDN modem would run closer to 100msec.

As for newbie's question, I think they call it a modem because the client's OS uses it like a traditional modem. But you are correct in questioning the terminology, since there is no modulation/demodulation from analog to digital.

Forcesho's response is correct in that some routers allow you to utilize the ISDN port as a virtual modem that the client PC can attach to over the network, but these routers are usually more expensive. He's a good guy so if you want to buy his ISDN modem, I'm sure it will be a good piece of equipment. I used to have a Motorola Bitsurfer Pro back in the day -- boy was I glad to get rid of it and get a router!

actually i'm just clearing out stuff, if no one takes it, it's gonna get thrown away, 5 bucks just covers shipping, i can even ship it to u and if it works, pay the shipping otherwise, chuck it and i'll take the small lost..

I am looking at the DLink DI-300W. If I buy it, will I also need an ISDN modem, or will the router take care of everything?

Thanks for your help.

That link doesn't work, and I can't find info on that model on their website. What is it?

 

[Palpatine]

Just go to www.dlink.com and click Search the D-Link Web and type in ISDN. It's the first one on the list returned.

That's weird about the link. It works when I click it.

Thanks,
