aLaw - Mulaw deals with the expansion and compression of audio signals.
USA - muLaw Mexico aLaw
In telecommunication, signal processing, and thermodynamics, companding (occasionally called compansion) is a method of reducing the effects of a channel with limited dynamic range. It is a combination of compressing and expanding (the word companding therefore is a portmanteau word), and is a variant of audio level compression.

We have a plant in Reynosa, Mexico. We have a Definity switch in our McAllen, Texas plant and then pipe the calls across a microwave system. AT&T is in Mexico but trying to get service for a downed line is like pulling teeth. We keep two international voice and one international fax line available to use if Reynosa has one of there continual power outage issues. It helps to have the switch on the U.S. side.

Power was on and off and on and off in Cabo during an install last year. It seemed to be a commom happening. Next time a generator will go along with the equipment just for the installation.
