This sample has one byte of Padding and a 2-byteДЇCS as well.

Shows one common application of the PPP general frame format: carryingДata.The value 0x0021 in the Protocol field marks this as an See Figure 33 for an example of how this format is applied. Padding may be applied to the frame, which concludes with an FCS field of either 2 or 4 bytes (2 bytes shown here) and a trailing Flag value of 0x7E. The variable-length Information field is formatted in a variety of ways, depending on the PPP frame type. The first three bytes are fixed in value, followed by a two-byte Protocol field that indicates the frame type. Always has the value в€°1111110В”ДЄll PPP frames are built upon the general format shown above. The FCS is calculated over the Address, Control, Protocol, It can be either 16 bits or 32 bits in size (default is Other layer two protocol error protection schemes such as the one used

This is a CRC code similar to the one used for In some cases, additional dummy bytes may be added to pad out the sizeДЄ checksum computed over the frame to provide basic protection againstД®rrors in transmission. For control frames, the control information For regular PPP data frames the network-layerДatagram is encapsulated here.
