Patent ID: 7225329

Claim:
A channel service unit/data service unit (CSU/DSU) coupled to a first data network and coupled to a second data network, the first data network being a wide area data network, the CSU/DSU comprising: a first data interface to the first data network, the first data interface comprising a telephony type interface; a second data interface coupled to the second data network via a data router separate from and external to the CSU/DSU, wherein the data router does not have encryption capability, wherein the second data interface comprises a packet data interface, and wherein the second data network includes a remote terminal, the remote terminal including decryption software, and wherein the remote terminal receives and decrypts the encrypted management performance data for display to a user of the remote terminal; a data processor responsive to the first data interface and to the second data interface, the data processor receiving input traffic data carried over the first data interface and generating management performance data based on measurements with respect to the input traffic data; a third data interface, the third data interface comprising a serial data interface and wherein the data processor is further coupled to the third data interface; and an encryption module coupled to the data processor, the encryption module to receive the management performance data and to produce encrypted management performance data to be communicated to the second data network via the data router coupled to the second data interface.
