With M7i there are only 4 PIC slots available... each ATM OC3 PIC has
2 ports and each GigE PIC has 1 port, there is a fixed GigE on the M7i
board, so a router with 3 GigE ports and 4 ATM OC-3 ports won't have
any PIC slot left. Could you change the router-switch connection to 1
ATM OC-12 ?

Why exactly do you need 3 GigE ports ?
