Note
On the Cisco 1900 series router, the numbering format for configuring an async interface is 0/slot/port. To
configure the line associated with an async interface, simply use the interface number to specify the
async line. For example, line 0/0/0 specifies the line associated with interface serial 0/0/0 on a WIC-2A/S
in slot 0. Similarly, line 0/1/1 specifies the line associated with interface async 0/1/1 on a WIC-2AM in
slot 1.
configure the line associated with an async interface, simply use the interface number to specify the
