  • Method and circuit for forming an ATM cell
    Patent number: 6826188
    Abstract: A method of forming an ATM cell having a fixed length from CPS packets according to the AAL2 protocol includes the steps of placing a header at a beginning of the ATM cell and then packing the ATM cell with the payload of the CPS packets. ATM cells are formed until the payload of the last CPS packet has been packed into an ATM cell. A TimerCU is not triggered until the last available CPS packet has been processed. If the last ATM cell formed is not full, it is padded until it is full.

  • Real time protocol packet handler
    Publication number: 20030095567
    Abstract: A Real Time Protocol (RTP) packet handler includes a protocol processor (44) coupled to a communications medium (26) and a central processing unit (CPU) (46). The protocol processor (44) receives IP packets (24) transmitted over the communications medium (26). Operating system (OS) software executing on the CPU (46) controls the operation of the protocol processor (44) via a host interface (57) and a dual port RAM (58). A switch (50) routes RTP type IP packets to a RTP handler module (48) running on the protocol processor (44). The RTP packet handler module (48) processes RTP packets. Non-RTP packets are processed by the OS software (46).
