Abstract

A method and system that detects protocol and configuration messages in a PPP packet without having to unframe the entire packet. The method includes a communication device (MT2) that receives a plurality data frames (S306), wherein the communication device is capable of ascertaining the beginning of an information portion (S305) within the received frames. The communications device detects whether the information portion contains configuration information, such as protocol and configuration messages of a predetermined type. In a first embodiment, the detection is achieved by the communication device unescaping (S315) the contents of a plurality of bytes and determining (S325, S330, S335) whether the escaped bytes contains the desired configuration information. In a second embodiment, the communication device determines whether the contents of a particular byte contain the desired configuration information, in escaped or unescaped form, and the communication device continues to sequentially process the bytes within the information portion until the bytes typically containing the desired configuration information are processed.
