67 / 109 page  XRT79L71 64 REV. 1.0.0 1-CHANNEL DS3/E3 ATM UNI/PPP/CLEAR-CHANNEL FRAMER IC - HARDWARE If the XRT79L71 has been configured to operate in the High-Speed HDLC Controller Mode, then the Receive Overhead Data Output Interface block will be disabled. A MORE DETAILED FUNCTIONAL/ARCHITECTURAL DESCRIPTION FOR THE HIGH-SPEED HDLC CONTROLLER MODE page 7 of word 3/12/04 The Functional/Architectural Description of the XRT79L71, when configured to operate in the High-Speed HDLC Controller Mode, can be found in Section _, within the document entitled: 79L71_Arch_Descr_HDLC.pdf -Architectural/Functional Description of the XRT79L71 1-Channel DS3/E3 ATM UNI/PPP/Clear-Channel Framer with LIU IC - High-Speed HDLC Controller Applications. BRIEF FUNCTIONAL/ARCHITECTURAL DESCRIPTION OF THE XRT79L71 - ATM UNI OVER DS3/E3 MODE If the XRT79L71 has been configured to operate in the ATM UNI over DS3/E3 Mode, then it will have the Functional Architecture as is presented below in Figure 4. Figure 4 indicates that the XRT79L71 consists of the following functional blocks. • The Transmit UTOPIA Interface Block • The Transmit Overhead Data Input Interface Block • The Transmit ATM Cell Processor Block • The Transmit FEAC Controller Block (DS3 C-bit Parity Applications Only) • The Transmit Trail-Trace Message Controller Block (E3, ITU-T G.832 Applications Only) • The Transmit SSM Controller Block (E3, ITU-T G.832 Appications Only) • The Transmit LAPD Controller Block FIGURE 4.
