About Carrier Access

Carrier Access (Nasdaq:CACS ) provides converged access technology
designed to streamline the communication network operations within
service provider, enterprise, and government markets. Carrier Access' technologies help our customers do more
with less. Therefore, a
given national scale rating implies a different level of risk compared
with the same international scale rating.
