(The W0 and W1 slot designations are for physical slot identification only.) Interfaces in the WICs are numbered from right to left, starting with 0/0 for each interface type, regardless of which physical slot the WICs are installed in. Some examples are as follows: • If slot W0 is empty and slot W1 contains a 1-port serial WIC, the serial interface in the WIC is numbered Serial 0/0. • If slot W0 contains a 2-port serial WIC and slot W1 contains a 1-port serial WIC, the serial interfaces in physical slot W0 are numbered Serial 0/0 and Serial 0/1, and the serial interface in physical slot W1 is numbered Serial 0/2. • If slot W0 contains a 2-port serial WIC and slot W1 contains a 1-port BRI WIC, the serial interfaces in physical slot W0 are numbered Serial 0/0 and Serial 0/1, and the BRI interface in physical slot W1 is numbered BRI 0/0. Voice Interface Numbering Voice interfaces are numbered as follows: chassis-slot/voice-module-slot/voice-interface If a 4-channel voice network module is installed in chassis slot 1, the voice interfaces are: • 1/0/0-Chassis slot 1/Voice module slot 0/Voice interface 0 • 1/0/1-Chassis slot 1/Voice module slot 0/Voice interface 1 • 1/1/0-Chassis slot 1/Voice module slot 1/Voice interface 0 • 1/1/1-Chassis slot 1/Voice module slot 1/Voice interface 1 Cisco 3700 Series Routers Hardware Installation Guide 1-6 OL-2180-08
