AND Coax

Coax is more alive than ever

The king is dead, long live the king. The same could be said of coaxial networks. Because those who are declared dead apparently live longer in multimedia provision. Thanks to its conceptual design based on frequency multiplex transmission, DOCSIS 3.1 (Data over cable service interface specification) enables significantly higher data transfer rates than the 1,000 Mbit/s currently offered by standard cable internet tariffs.

Added to this are the classic advantages of cable TV over IPTV: no bandwidth requirements, top picture and sound quality, truly live with no delay when switching channels, no additional equipment required, preservation of user anonymity vis-à-vis the transparent customer, etc.

With its integrated CAD and engineering functions, AND Coax offers comprehensive documentation, planning, and service support for coaxial networks, including headends and in-building networks, with detailed information on all network components, including settings, expansion status, calculations, georeferences, and addresses.

What AND Coax does in detail

The AND Coax license is basically the AND FiberCo license without the fiber management features; microduct management is also not available. However, fiber and copper sections of the network can be displayed. The following information may also be relevant for coaxial network sections.

Channel management

The signal source can be administered at the headend allowing the TV channels to be defined according to the frequency plan. AND takes the relationship between the signal sources and outlets into consideration so it is possible to determine TV channels received by each and every customer. For example, the user can go to an address in the AND documentation and check to see which channels the customer receives.

Power supply

AND enables the user to manage power supplies to the network. The supplied area can be automatically determined and if requested, can also be colour-coded. Using the NIS function it’s possible to quickly see exactly which components are fed by which power supplies.

A power supply check calculates the power current and available voltage for every network component and provides a warning when:

• An element (requiring powering) is not supplied
• An element receives too little voltage
• A powering unit is overloaded
• There is a short circuit
• A component which should not receive voltage actually does so
• The permissible power through a component connector is exceeded

For a higher degree of accuracy the power supply calculation can reference the U/I characteristics in the libraries and takes the individual consumption of each module in the amplifiers and fibre node into consideration. AND Coax is available as a part of the AND SystemSolution or as a stand-alone application where data is stored to files.
