ie ISDN maximum bandwidth is 128K is it possible that
can 2 isdn lines be connected simultaneously on ONE PC
or through ISDN ROUTER and can get 256k Bandwidth.

Plz do reply..waitinggggggg

THank and Regards

Quick answer is yes; as long as your router can support it you can aggregate any number of B-channels together to get any bandwidth you want. Keep an eye on the call charges though

Re: ISDN INFO! 12 years 5 months ago #16920

so u mean we can get a client connect at 256Kbps with one ip address assigned to him ? a full pipe of 256K instead of 2 128k pipes ?


Re: ISDN INFO! 12 years 5 months ago #16937

Yes, as long as the OS on the router is capable of aggregating them together

Add on:

I believe you're refering to PRI lines in ISDN, which in that case, yes, you can achieve 256kbps and more, depending on how many B-channels you choose to get.

Not so sure it is as simple as that. Alot will also depend upon your providers ability to assign a single IP to 2 x ISDN2 (128Kb/s) you will need to check.

If you are talking about ISDN PRImary rate (2.048 mb/s in 64Kb/s channels) then wouldn't be so much of an issue.

Define exactly what you want then ask your provider how best they can provide it, and what they recommend at the customer site. If you are thinking of 2 x ISDN2 (or BRI Basic rate) then you will need 4 x Copper Pairs, 2 x NTU and a decent router to aggregate the channels.

Hope this helps
