GFC Halt Path REI/RDI Line REI/RDI System Loopbac k Line Loopback Intel IXF6048 51/155/622/2488 Mbit/s SONET/SDH Cell/Packet Interface Datasheet Intel IXF6048 is a single-chip interface solution for the transport of ATM cells or HDLC frames over SONET/SDH. Intel IXF6048 can operate as a quad 51/155/622 Mbit/s or as a single 2488 Mbit/s SONET/SDH processor. When configured in ATM UNI mode, it interfaces with an ATM layer device using the industry standard UTOPIA interface (Levels 3/2/1). When configured in Packet Over SONET mode, it transfers the PPP frames using a UTOPIA-enhanced interface, based on the ATM industry standard UTOPIA, which supports the transfer of variable length frames. Product Features Supports the UTOPIA Level 3 (single 64- Applications bit, 32-bit, or quad 8-bit), Level 2 (single 8/ 16-bit), and Level 1 (quad 8/16-bit) WAN and edge ATM switches interface modes. Layer 3 switches Implements a GFC halt function (ITU I.150 Video and File Servers and I.361). Broadband Switching Systems Handles full J0/J1 trace identifier processing. Features SOH, POH and Alarm insertion/extraction ports. Maps ATM cells or HDLC frames into one Hardware assistance for APS STS-48c/STM-16c/STS-48/STM-16/STM- implementation, via K1 and K2 bytes. 4 or four STS-12c/STM-4c/STS-3c/STM- 1/STS-1 SONET/SDH signals. Provides a 16-bit microprocessor port. One-second counters for B1/B2/B3, M1/G1 In POS mode, each channel performs SPE 43 REI, etc. scrambling (1 + X ), HDLC processing, and offers a UTOPIA-type FIFO-based 600 TBGA package -40 C to +85 C POS interface. operating conditions low power, 3.3 V operation, 5 V tolerant I/O Figure 1.
