Claim:
A system, comprising: a channel service unit/data service unit (CSU/DSU) having a first data interface to communicate via a telephony type network, and a second data interface to communicate via a local area network, wherein the CSU/DSU produces management data related to communications received via at least one of the first data interface and the second data interface, and wherein the CSU/DSU encrypts the management data, encrypts the communications received via at least one of the first data interface and the second data interface, and sends the encrypted management data and the encrypted communications to a data router to be communicated to a remote terminal of the local area network; and a data router coupled to the CSU/DSU to receive and route the encrypted management data and the encrypted communications to the remote terminal, wherein the data router is separate from and external to the CSU/DSU and wherein the data router does not have encryption capability.
