Claim 12:
13. A method, comprising:
determining whether a message received via a router of a telecommunication device is directed to a secure data circuit of the telecommunication device; and
responding to a determination that the received message is directed to the secure data circuit by:
identifying a communication pipe identifier and an instruction code associated with the received message;
determining whether the instruction code includes an instruction to reassign an end of a communication pipe associated with the communication pipe identifier from a port of the router to a port of another circuit of the telecommunication device; and
responding to a determination that the instruction code includes the instruction to reassign the end of the communication pipe associated with the communication pipe identifier from the port of the router to the port of another circuit of the telecommunication device by:
comparing the instruction code to a parameter associated with the communication pipe identifier and stored in a filter table, the parameter indicating whether the instruction requesting reassignment of the end of the associated communication pipe to the another circuit is authorized; and
blocking the received message from reaching the secure data circuit of the telecommunication device or passing the received message to the secure data circuit hbased on the comparison.
