                  Avantel readies InterconnecT for New Year

              Heightens Intec's profile in Central/Latin America

December 12th, 2001 Mexico/London: Avantel, one of Mexico's leading domestic
long distance operators, is on schedule to go live with Intec's InterconnecT
solution in January 2002. Intec Telecom Systems, a global provider of
Operation Support Systems (OSS) for telecom companies, sold its InterconnecT(TM)
billing software to Avantel earlier in 2001. Avantel cited the proven
performance of InterconnecT as the primary reason for its selection. Other
important considerations included InterconnecT's low implementation cost and
user flexibility in supporting future services and market requirements.


'Intec's billing solutions have a global reputation for performance and
reliability in major operators, and this was key to our success in winning
Avantel,' says Victor Salazar, Intec's Director of Sales for Mexico, Central
America and Caribbean.  'InterconnecT is a proven product which will maximize
Avantel's revenue stream from the first day of operations in 2002.'


Avantel has grown from a leading domestic long distance company into an
Internet and local telephone service provider for corporate and residential
customers.  InterconnecT  will play a vital role in calculating
interconnection revenues and producing accurate billing information. In
addition to these capabilities, InterconnecT will also provide support for
other complex billing areas including number portability and least cost
routing.


'InterconnecT is a sophisticated, low-risk solution that will help Avantel
deal with the growing demands of intercarrier billing across all network 
types', said Kevin Adams, Intec's CEO. 'Intec's growing presence in the CALA 
region will also ensure that Avantel gains our experience in technical 
implementation and service support.'
