I have two routers 1760 serie with a WAN card WIC-1T inserted in slot 0.
Unfortunetly, I cannot use the command "controller E1 0/0" in order to configure the source of the clock.
Nor can I use the command "sh controller E1".
The command "show diag" tells me that the card WIC-1T has been recognized by the router.
Where is the problem ? Is there a special image that I should use ?
My IOS image file is : c1700-sy-mz.122-11.T8.bin
Thank you for your reply.
