Since i got my 1604R isdn router my total bandwidth has been 14kbps. Both of my b channels are dialing out, but still 14k downloads. My telco company came out twice saying the line is good. Call cisco support they check my config file saying it was fine, but i really don't think so. Seems like the d channel is only be use, but i thought you couldn't use the d channel for data. Someone please help situation going on for 3 months. I don't know who to blame cisco or telco, thanks [sig][/sig]

Have you tried putting another ISDN device on the circuit to determine wether are not it is a cpe or Telco issue ? This will allow you to start trouble shooting in the right direction . Have you contacted your ISP ? The question for your ISP is , Is the line that your dialing into set up for ISDN and or is there another number less published they can provide . ( this would test the ISDN backbone to the internet ) . The only other question I have at this time is did you remove your lan from the router and ping across the internet? is your responce time quicker ? ( <-- just a thought ) . Your conf looks ok . I'll look at this conf in the lab , but again I think its ok ... [sig][/sig]
 
I did contact my ISP they said everything is fine. They even provided 2 different #'s to dial in still the same. No i did not remove my router from my LAN. [sig][/sig]
 
MY downloads at different times of the day. Always about 12-14.5k [sig][/sig]
 
Try removing ppp multilink and only dial out with one channel (remove the second SPID)and see if you get 56 or 64kb as you should. If so, I'm guessing the channels aren't bonding properly, and it's doing some sort of round-robining out both devices and half the packets are getting dropped/being reset, or something odd like that. I saw a simular situation where another engineer had done the config, and as soon as the second channel came up, bandwidth went down the tubes (like what you're talking about). I actually found the configs (before and after):

Anyway, I'd just configured a simular router 2-3 days before, and rather than troubleshoot what another lazy engineer had set up, I just wiped it and used what I knew just worked (and it did just work).

Hi

I have an Off-Topic remark:
Never post passwords (even encrypted ones) because they can be hacked!

just for example: unix72, your enable password is jjg61

be carefull!

Thanks for the advice jroysdon hope that works and ariev your way off!!!!!!!!!! [sig][/sig]
 
Perhaps this may not be what is happenning, but on the off chance it is...
When you think of the bandwidth you should have with two B channels, you thinking 128Kbps. Now when you're doing a download over this, you're seeing download speeds that read 14KB/Sec. Is this correct? If it is, your throughput is about what you should expect to see and therefore, there is no problem. Your bandwidth is measured in bits pre second, but the download is measured in bytes per second. The download speed of 14KB/Sec equates to a bitrate of 112kbps, or pretty close to your total capacity. Hope that helps. [sig][/sig]
 
I'm getting 14kbps on downloads i know that for a fact. it takes 6 minutes to download a 5mb file. (Analog modem speed) [sig][/sig]
 
The last responder is correct. If you look at the numbers, a 5 meg file is 5,000,000 bytes, you are downloading at 14,000 bytes per second. So 5,000,000 / 14,000 is 357 seconds or 5.9 min. And 14K download speed is correct for a 128 KiloBIT download, 128,000 bits per second = 16000 KiloBYTES per second. So you are very close to top speed.

Understand?
 
No im downloading at 14,000 bits per second. if i was getting my full bandwidth of 128k both channels it should take less than a minute to download a 5mb file. My partner haves a isdn connection he gets mostly 128k downloads.(128,256,384,512,640,768,896,1,024k)He downloads 1mb files in about 10-15seconds. [sig][/sig]
 
Please check your Telco line for possible taps and also your inside wiring config. also ask youe telco tech to check your loop lengh you could be to far from office
 
The last comment about the loop being close to out of limits could be a factor . It's possible that a repeater is needed on the ISDN circuit . This normally will cost about and additional $20.00 a month . I'm wondering only because I have not seen you post
any info on this . Have you installed your Equipment to another ISDN circuit ,and or installed some different equipment on your present ISDN ? If so what HAPPEN >? [sig][/sig]
 
Sorry everybody but im new to isdn technology i made a mistake. I thought for each channel the bandwidth is 64kbytes but really it's only 64kilobits together total=16kbytes. Hey everybody thanks so much for helping out now i know. [sig][/sig]
