UPD98402A LOCAL ATM SONET FRAMER

DATA SHEET MOS INTEGRATED CIRCUIT µPD98402A LOCAL ATM SONET FRAMER The µPD98402A is one of the ATM-LAN LSIs and incorporates the TC sublayer function in the SONET/SDHbased physical layer of the ATM protocol. The main functions of the µPD98402A include a transmit function for mapping ATM cells received from the ATM layer onto the payload block of the SONET STS-3c/SDH STM-1 frame and sending them to PMD (Physical Media Dependent) in the physical layer, and a receive function for separating the .

UPD98402A Features

* Provision of TC sublayer function of ATM protocol physical layer

* Support of SONET STS-3c frame/SDH STM-1 frame format

* Provision of stop mode for cell scramble/descramble and frame scramble/descramble

* Disposal/transitory selection of unassigned cells is possibl
