Hello all,

Well I want to connect to the internet wirelessly using my Dial-up account. I got an H1940 and a SonyEricsson T616. I tried both Bluetooth and Infrared. The phone starts dialing, and as soon as the other PC answeres, the T616 seems to drop the call. Then it re-dials.

Then I get a message on my H1940. When using Bluetooth it says "No computer found on the other side of the line (err something like that lol)" And when using infrared it says "Unable to connect for unnknown reasons, please check your setting".

I played around with every possible setting, but it is no help at all. The problem seems to be the cellphone. For some dumb reason it dropps the call right after the other PC "picks up" the call.

If I dial the number normally my self on the cellphone, it answers perfect, and I hear the wonderfull screeching noises of a dial-up pc ;p

Any tips at all?

Thanks in advance guys.

Completely unrelated, but this happened with me last week. My laptop couldn't connect to a RAS server if using the built-in landline modem. Then I used the Zoom Bluetooth modem I had here for review and the connection went through. Back in the office I tested the same laptop with another landline and the built-in modem worked fine.

My point is: perhaps it's not a problem with your mobile phone, but with the other modem? Sometimes if you add too many devices in the same landline you'll have strange behaviour. One phone rings and the other doesn't. The modem connects only at 14.4kbps or get no connection at all.

Are you able to check the other modem? See if there are other devices (phone, called id display) in the same line? Are you able to dial in using another modem instead of your mobile phone, just to check that this connection works?

And of course, do you have data enable on this account?

no need for a data account. I wanna do Dial-up not GPRS.

Check other PC?! err let me clarify. You know dial-up internet? Say you have a PC. That PC has a dial-up modem that u stick a phoneline into. Then you dial-up the internet provider, be it AOL, MSN, Sympatico whatever ;p

Imagine my Ipaq as a PC. And the phoneline would be my T616 ;p

The problem lies either in the phone, or some sort of misscomunication between the two. They connect to eachother easily, and work wonderfully, but for some reason, the T616 drops the call as soon as the ISP computer picks up the call. Dunno why ;p

Yes, you need data enabled to use CSD connections. In most cases the network would not try the connection, but it may in some case dial out - to then disconnect.

And please calm down. I know what dial up is and how it works. I agree my suggestion to check the line wans't the right answer - I misread the question...

Dude I am calm, and I am not being aggressive towards you, am sorry if you thought I was.

Anyways, explain HCSD connections plz? How would I enable that service? Also why would the line drop the call, when PPC dials, yet not drop it when I dial?

CSD (Circuit-Switched Data) is the method used to transfer data on GSM networks. Because of the number of time slots used it only allows for 9.6kbps speeds. HSCD (High Speed Circuit-Switched Data) was created to allow higher speeds (up to 57.6kbps) based on more time slots used. But some networks restrict this to a max of 14.4kbps. Still, this is a circuit switched instead of packet based (GPRS), and it's charged per minute.

Circuit switched connections establish a physical connection between the two parties in the call. Exacltly what you'd expect in a standard phone call. That's why it's charged per minute, since you're using circuits.

As I said, some operators will require you to ask for CSD/HCSD to be activated. This is not related to GPRS.

Maan, that is such a rip-off. I thought only charges to be applied would be the airtime charge.

If you're using CSD, yes the charge is only the airtime. Depending on the company this will come out of your minutes included in your plan. On Vodafone NZ dial up comes out of available minutes first, for instance. You don't pay to have this feature added to your account.

This is different from GPRS, which you pay per traffic, not time.
