AT&T EXTENDS CAPABILITIES OF SOFTWARE DEFINED NETWORK

 AT&T EXTENDS CAPABILITIES OF SOFTWARE DEFINED NETWORK
 BASKING RIDGE, N.J., Jan. 7 /PRNewswire/ -- AT&T (NYSE: T) today


extended the capabilities of its Software Defined Network (SDN) offering with a new feature that enables customers to access their networks from remote locations with greater security. Called the SDN Card Guarantee, the feature enables customers to optimize use of their networks and better control costs.
 "Most SDN customers want their employees to have remote access to their networks so they can take advantage of the network's innovative features and low costs no matter where they happen to be," said Glenn Starr, AT&T's product manager for Software Defined Network. "In the past, some customers were wary of allowing employees to access the network remotely because of potential misuse. With the SDN Card Guarantee, any customer can have remote access to their SDN without the fear of fraudulent use."
 The Network Remote Access feature of SDN enables customers to place SDN calls from any TouchTone telephone by entering their authorization codes on the keypad, plus the telephone number. At times hackers have been able to access Software Defined Networks and, through various means, been able to acquire a valid authorization code. Using the valid code, hackers and others have then been able to place calls on the network.
 With the SDN Card Guarantee, Starr said, codes can be instantly disabled from AT&T's Network Fraud Detection Center in Chicago once usage exceeds a customer-defined limit. Customers simply assign a particular monthly dollar amount of usage permissible for all their SDN authorization codes. Once usage on that code exceeds the pre-set amount, the code is disabled and can no longer be used to complete calls.
 "This Software Defined Network feature enables our customers to extend SDN remote access to more of their employees, thus cutting their long distance costs," Starr said. "At the same time, the feature effectively frees them from worrying about potential misuse of their network. That's an enhanced level of security unmatched in the industry, and it's just the first of many enhancements we'll be adding to SDN's capabilities this year."
 AT&T Bell Laboratories and the Technical Advisory Committee of the SDN Users Association were instrumental in developing the feature, Starr said. Members of the advisory group worked closely with AT&T in defining and testing each of the feature's attributes.
 The technology underlying the feature includes real-time data communications links among No.4ESS(TM) switching machines on AT&T's worldwide intelligent network, AT&T's call processing and billing systems and the dedicated Network Fraud Detection Center in Chicago. The combination enables the center to track, in real time, each call made using a specific authorization code.
 Software Defined Network, AT&T's virtual private network offering, enables large business customers to use AT&T's public switched network as though it were their own private network. With more than 1,300 business customers, SDN is the most widely used, and fastest growing virtual private network offering in the industry, Starr said.
 The SDN Card Guarantee feature will be available in the second quarter of 1992. Pricing will include a monthly recurring charge and will be based on the number of codes covered.
