I accepted a job to install a Cisco 804 on an ISDN 128K circuit (BRI), should be simple right!!
I got there they had an ISDN (PRI) running into a PBX and wanted me to connect the 804 to a 25 pin connector they had hanging from a DCD card. They said they had programmed 2 channels to connect the 804 through the PBX to their ISP. Fast Step got an error that it could not dial out to the ISDN, I talked to BellSouth which supplies the ISDN PRI. They said they seen the PBX blocking the 2 channels going to the router. I told the PBX guy that a normal BRI which the 804 supports has 2 - 64K data channels & a 16K signaling channel & that the reason it is not working is because it has no way to send the ISP the signaling. Is this a correct assumption? Is there a way to manually configure the router to work in this scenario, if so could you send a link to some sample configurations.
