Point to Point T1 Connection w/ 1720

[andylai2k9]

Hi all,

I try to setup a point to point T1 for 1 device connected to another device on other location.
After both router are up, I can ping the following from Office A console
10.5.253.1
10.5.253.2
10.5.4.254
10.5.0.254
10.5.0.6
10.5.4.6

But I can't ping any thing from the Ethernet port except
10.5.253.1
Please help.
