The present invention includes a support frame wherein the support frame defines the peripheral edges of the shape of the support frame. The support frame includes a central aperture surrounded by a plurality of support members. A cover member is secured to the front side of the support frame so as to cover the central aperture. A bladder is suspendedly mounted within the central aperture of the support frame and extends downward from the upper end to the lower end of the support frame. The bladder includes a nozzle that is journaled through a hole in the cover member so as to provide dispensing of a beverage subsequent the beverage dispenser being secured to a wall. The cover member includes decorative indicia.

Unlike conventional methods and systems for locating ingress, which only monitor the upstream path, a method and system of locating ingress by monitoring the downstream path is provided. A test system measures the signal quality in the upstream path and in dependence upon a noise level being above a predetermined limit, polls a plurality of terminal equipment devices to return a downstream signal quality measurement. The test instrument analyzes the downstream signal quality measurements to locate an ingress source contributing to the noise.

Ingress noise labeling tags are coupled into the signal path at various nodes of a cable network. The tags imprint a unique electric signature into a local ingress noise, making the noise identifiable at the headend of the network. In one embodiment, tags do not require external control signals to operate, the electrical response of the tags being determined by present and/or past magnitudes of the return path signal. Such tags can be made entirely passive, not requiring a control signal or an external source of electrical power.

The present invention provides a test device and a method enabling automatic detection of an imbalance in a power level of a channel. The test device includes a tuner, a power-level measurement system, and an evaluation unit. According to the method, a test channel is selected from a plurality of channels, by means of the tuner. A power level of the test channel and a total power level of the plurality of channels are measured, by means of the power-level measurement system. A ratio of the total power level of the plurality of channels to the power level of the test channel is then evaluated, by means of the evaluation unit, to detect an imbalance in a power level of the test channel.

The present invention provides a test device and a method enabling automatic detection of an imbalance in a power level of a digital channel. The test device includes an attenuator, a tuner, a demodulator, and an evaluation unit. According to the method, a plurality of channels are attenuated at a plurality of attenuation levels, by means of the attenuator. A digital channel is selected from the plurality of channels, by means of the tuner. A modulation error ratio (MER) of the digital channel is measured at the plurality of attenuation levels, by means of the demodulator. A variation of the MER of the digital channel with attenuation level is then evaluated, by means of the evaluation unit, to detect an imbalance in a power level of the digital channel.

The testing equipment of the present invention calculates a single 'AGC stress' value, which provides an indication of the stability of the level of a digital carrier based on the change in gain required to stabilize the power of an incoming cable signal over time. Ideally the AGC stress value is rated on a scale, e.g. 1 to 10 or 0 to 5, and is fed into the DQI measurement system as a new data model.

A test device enables DOCSIS link testing in a HFC network without requiring the CMTS or other router at the headend of the HFC network to respond to ICMP messages. The test device includes a test packet generator for generating test packets having a destination Internet protocol (IP) address associated with a test device, a memory for storing transmission parameters of the test packets, and a test packet evaluator associated with the IP address in the generated test packets. The test packet evaluator receives the generated test packets after the test packets have been routed through a router at a head end of a HFC network and compares reception parameters for the received test packets to the transmission parameters stored in the memory.
