I have several remote sites that will be set up to use ISDN as a backup if the data T1 fails.
At each remote site, I am planning on having an external ISDN terminal adapter attached to the AUX port.
Since the ISDN TA has a serial interface it should operate just like a standard analog modem. I do realize that the AUX port is limited to 115k where the ISDN would max at 128k with both channels running. Is there any issue to this than just a slight reduction in speed?
Are there any gotchas that I am missing here?
