T1-CSU/DSU Configuration

Hi,

I need to configure 2 T1-CSU/DSU modules on a router and I need some assitance with the how to configure the interfaces. Protocol to be used is PPP.

I am not clear on which IP address to assign on the interface as I was provided with the following (not exact IPs) from the service provider:

WAN Link Details:

WAN Link IP Address: 64.12.59.91

AR Serial INT IP Address: 64.12.95.92

CR Serial INT IP Address: 64.12.95.93

WAN Link Subnet Mask: 255.255.255.252

WAN Link IP Address: 64.12.59.91

AR Serial INT IP Address: 64.12.95.92

CR Serial INT IP Address: 64.12.95.93

WAN Link Subnet Mask: 255.255.255.252

Any help would be greatly apprecaited.

Thanks,
