TCS Backs Federal Communications Commission's Efforts to Develop National Commercial Mobile Alert System

ANNAPOLIS, MD (NASDAQ: TSYS), a leading provider of mission-critical wireless communications, today announced that it has joined national wireless carriers in support of the Federal Communications Commission's (FCC) Commercial Mobile Alert System (CMAS). The CMAS is intended to transmit geographically targeted emergency alert text messages conveying imminent emergency threats.

"TCS applauds and fully supports the FCC's ruling on the development of a national emergency alert program," stated Maurice B. Tosé, President and Chief Executive Officer of TCS. "During times of emergency, it is critical to put accurate and timely information directly into the hands of consumers. With our strength as a leading player in consumer wireless safety, combined with our experience in delivering billions of text messages daily, we look forward to the opportunity to work with the government and wireless operators to make CMAS a reality."

The FCC summarized the alerts that devices would receive under the system:

--  Presidential Alerts - national emergency-related alerts delivered to
    the American public that would preempt any other pending alerts
--  Imminent Threat Alerts - alerts with information on emergencies that
    may pose an imminent risk to people's lives or well being
--  Child Abduction Emergency/AMBER Alerts - alerts related to missing or
    endangered children due to an abduction or runaway situation
    

"This system has the potential to significantly impact the way Americans receive critical warnings on the go, whether they are at home, work, or vacationing," FCC Chairman Kevin Martin said in a statement.

TCS' Wireless E-911 system is used to automatically pinpoint wireless caller location information and ensure that consumers' emergency calls are routed to the appropriate public safety answering point (PSAP). TCS not only provides Wireless E-911 service for over 140 million cell phone subscribers today, the company also delivered 80 billion text messages in the U.S. last year, representing about 25% of the total 363 billion messages as reported by the Cellular Telecommunications and Internet Association (CTIA).
