I need some help with an ISDN BRI setup we are trying to do. We are trying to hookup a Cisco 1604R ISDN BRI Router to the Hiper DSP Total Control, Ameritech filled the order for BRI two B channels and 1 D Channel and we can manage to hook one B channel no problem but when we try to bond or multilink the two B channels together it will hookup the second channel for approximately two or three seconds and then it dies and about one second later the first B channel that had been hooked up dies. We are running Hiper DSP code 2.0.51 on the particular Hiper DSP card it is on and Hiper ARC code 4.1.59-6. 3 Com looked at our setup on the Total Control and said it look right, Cisco looked at the 1604R and said it looked right. And Ameritech said the B channels are setup right. Now we are lost, something is not right so someone is wrong and we cannot figure what it is. Does anyone have any ideas or know if there is something the Telco has to do to allow two B channels to bond on a BRI setup? Ameritech says they do not that it is all done at each equipment end which I know but we are searching for anything at this point. Any help would be appreciated. Thank you, Clint R.
