1. On the Cisco 2901 router, the numbering format for configuring an asynchronous interface is 0/slot/port. To configure the line associated with an
asynchronous interface, use the interface number to specify the async line. For example, line 0/1/0 specifies the line associated with interface serial 0/1/0
on a WIC-2A/S in slot 1. Similarly, line 0/2/1 specifies the line associated with interface async 0/2/1 on a WIC-2AM in slot 2.
2. Applies only to Cisco 2951, Cisco 3925, and Cisco 3925E routers.
3. Applies only to Cisco 3945 and Cisco 3945E routers.
4. Applies only to Cisco 2921 router.
5. Applies only to Cisco 2951, Cisco 3925, and Cisco 3925E routers.
6. Applies only to Cisco 3945 and Cisco 3945E routers.
7. Applies only to Cisco 2951, Cisco 3925, and Cisco 3925E routers.
8. Applies only to Cisco 3945 and 3945E routers.
