ISDN channel bonding not happening

[edlance]

I just had ISDN installed since I can't get DSL or cable. I have a 2B + D line (BRI, 128K). Standard SBC 5ESS point-to-point. I am running a Hayes Accura external ISDN TA through a high speed PCI serial card (port speed is set to 460.8Kbps ob both the serial card and the TA). The TA has been setup correctly from what I can tell and does work (I am on it right now on single channel (64K) ISDN hookup). The account I have with my ISP is a 128K account, but I am unable to get the B channels to bond.

I have searched the net and tried every AT command string, setting, etc I can find in the dial-up network settings to no avail. The TA configuration software says it is set for multilink PPP, and I even have STAC compression on. I don't even get any compression, even on this single channel connect.

Anyone have any experience with the Hayes Accura TA? Did I overlook something? This is driving me nuts!

Thanks!

Is there a way to dial a 2 channel non-bonded call? Maybe your ISP doesn't support the bonding protocol (quite possible). You also need to look at the cause code when the second call fails, it will give you a good idea of the problem. Its more likely your BRI was provisioned by SBC as NI-1...does your line have 2 different telephone numbers and/or spids? If so then you should change the switch protocol in the settings to National ISDN-1 (or NI-1).

Anyway, I'm just throwing out some ideas. Hopefully I'm close on one of them. Good luck.

Actually, I've fixed the problem (actually 2 problems it seems)....I got a different modem. I now have a 3Com Impact IQ modem and it is connecting at 128K fine, but the second problem...I'm still only getting 64K throughput...it's like one channel is just sittng idle even though it connects.

I fixed that too....I loaded WinXP and it all works just fine now. I talked with the ISDN tech at the ISP and we sat for 2 hours trying to configure my former Win98 load and couldn't get it to use the full 128K.

Oh well, I actually think I like WinXP and I now have my full 128K throughput so I'm happy.

You beat me to it.

My advice would have been to replace the modem and upgrade to XP.

Glad you got it sorted.
