I'm trying to setup a Cisco 1721 router for a customer that will be using it for video conferencing.. They will have multiple sites with a Full T1.which are all provided by Global Crossing on their private VPN network. Each location will have a 1721 with a WIC-1DSU-T1.
I have the T1 interface setup as follows...
Linecode - B8ZS
Framing - ESF
Timeslots - 24 speed 64
Clock source - Line
IP (One of the Serial IP's given.
That's pretty basic to setup, but they have given me two serial IP's and one LAN IP. My asumption is that I set the WIC card to one of the two Serial IP's and then the LAN IP will be given to the FastEth connection. Am I correct? Also, is there any routing that I will have to setup between the T1 interface and the FastEth? This is where I lack the understanding. I do no have the router in place yet, but tomorrow I will be instaling it at the first location. Any help is appreciated.
