Specifications Chapter 1 Overview of the Router Table 1-6 Interface Numbering (continued) Slot Number Slot 0 Slot 1 Slot Type EHWIC/HWIC/WIC EHWIC/WIC/VWIC Slot Numbering Range 0/0/0 to 0/0/0 (single-wide) 0/1/0 to 0/1/0 (single or double-wide) 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. Specifications Table 1-7 lists the specifications for Cisco 1905 and Cisco 1921 series routers.
