A customer premises network access device includes a housing and a network interface unit at least partially disposed therein, for communicating with a data network and providing access to the data network to a user. The customer premises network access device also includes a processing unit disposed in the housing and connected to the network interface unit. The processing unit is configured to determine an aggregate amount of data associated with the network interface unit over a predetermined time period, and to determine a data value based on the determined aggregate amount of data. An exterior-facing display viewable to the user from outside the housing receives the data value from the processing unit, and displays an indicium based on the display value to the user.
