Abstract

Secured connections are provided over a telephone access network using encryption/decryption equipment installed at a customer's premises and at a network facility. For outbound calls, the access network is secured before the destination number or any other critical information is sent over the access network. Inbound calls are routed through a secure center to prevent the identification of the calling party and to secure these communications over the access network. By providing encryption/decryption equipment at the network facility, the system provides secured connections over the access network regardless of whether the remote party is secured. The system also may be configured to provide end-to-end secured connections.
