How do you go from a 4-Wire system to a wireless system?

In many cases it is possible to enable a device that is designed to communicate over wire-line using a specialized cellular gateway that can be configured emulate legacy 4-Wire E&M while also making the conversion to IP. USAT achieves this solution by such a gateway on both ends of the communication loop. Contact USAT Corp. for more information if your business is being burdened by an aging 4-Wire infrastructure and you are looking for an alternative or fix in the short-term. Clients have reported that their telecomm providers are simply not interested in repairing DC line systems anymore.
