ISDN tweak guide (Windows 2000)


Now select the Options tab. I would recommend you leave the first option on, & unless you use the same details for your OS as your ISP (not recommended) leave the latter two options in Dialing options Unticked. The second option is down to user preference. Set the time between redials to 1 second, there is no real reason why it should be anything more. Leave X.25 well enough alone unless you need it.

128k connections

If you can only have 64k on this line then the multiple devices section will be blanked out. However if it is available to you, you are in luck.

For an optimal connection, set the option in multiple devices to Dial all devices. This will always connect you at 128k, providing you have two devices enabled in the “general” tab as mentioned earlier. 128 is nearly always noticeably faster than 64k, & for most of you I would recommend connecting at 128k all the time. However, this also costs double the amount that a 64k connection does, & as such some may want to be a bit more conservative with this setting. Set it to Dial only first available device to connect at 64k only. Windows 2000 has the unique option of “bandwidth on demand”, which means you will always connect at 64k, but windows can activate the other ISDN line as necessary. In theory, it is an extremely useful option, although I found in practice that windows rarely activated the second line, as the speed of incoming data from the internet changes dramatically all the time. However I would recommend people try this option. To enable it, select Dial devices only as needed. Click on Configure. Here you can specify under what conditions windows should dial up the second line.

I would recommend using the settings I have here, although it doesn’t matter too much what you specify. One thing I would add though is that data flow rarely uses 100% (or even 95%) of the available bandwidth due to other constrictions. Therefore, windows will not dialup the second line, even if it would help.
