Claim Text:
1. A network infrastructure device for processing a data stream received via a communication channel, the network infrastructure device comprising: a receive interface and a transmit interface coupled to the communication channel; and a set of signal processing blocks operationally coupled to the communication channel between the receive interface and the transmit interface; wherein the network infrastructure device is configured to analyze the data stream to identify an occurrence of a predetermined data pattern; wherein the network infrastructure device is further configured to operate in a first channel mode by: performing at least one of adding at least one signal processing block to and removing at least one signal processing block from the set of signal processing blocks operationally coupled to the communication channel upon the occurrence of the predetermined data pattern, and processing the data stream based on the predetermined data pattern, and providing the data stream to the transmit interface after processing; and wherein the network infrastructure device is further configured to operate in a second channel mode by passing the data stream from the receive interface to the transmit interface without processing on a condition that the predetermined data pattern is not identified in the data stream; wherein the data stream changes from a VoIP session to an intersystem link protocol (ISLP) session; and wherein the predetermined data pattern is a sequence of ISLP flags.
