Flash slot

56482

The slot number for all WIC interfaces is always 0. (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
