Low Voltage Communication Symbols

[fsulik]

I create floor plans and wiring diagrams for communications cabling systems (voice, data, audio, cable tv video distribution, video security cameras, card access systems, overhead paging, fiberoptics, etc).

Each of these trades use symbols to denote various types of electrical components used in communications.

Is there a library of communication symbols that can be purchased through Autodesk or elsewhere?

Thanks
