3.2.5Configuring device ports
When a device is selected in the device list, the available ports on the device are
grouped and listed. Comma ports are enumerated using de device's name, the card
index in the device and the port number. I.e. device:a2-5 would indicate the fifth port
on the second analogue card (a – analogue, b – bri, p – pri) in device. Doh
