You can then start each device with wanrouter start. This starts all devices and populates /dev/wanpipe/ with a device for each channel (for example, for a T1 it will create /dev/wanpipe1_if1 to /dev/wanpipe1_if24). A span and channel number physically identifies each device. This is important to keep in mind, as it...
