I prepare Cisco1841 as CE router of MPLS and need to set up US.Robotics 56k modem to connect to Cisco 1841.
This modem enable for me to login via PSTN when MPLS is down.
According to URL above, It seems that I need to connect like following
PSTN line----Modem --DB25--console cable --Cisco1841.
Is it right? and
Are there anyone who knows which port of Cisco1841 should be used?
I am wondering AUX port or Console port?
URL above says that I need to console port.
If console port in this case, what is there aux port for ?
