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
STS-48c/STM-16c/STS-48/STM-16/STM-
4 or four STS-12c/STM-4c/STS-3c/STM-
1/STS-1 SONET/SDH signals.
■ In POS mode, each channel performs SPE
scrambling (1 + X43), HDLC processing,
and offers a UTOPIA-type FIFO-based
POS interface.
■ Hardware assistance for APS
implementation, via K1 and K2 bytes.
■ Provides a 16-bit microprocessor port.
One-second counters for B1/B2/B3, M1/G1
REI, etc.
■ 600 TBGA package; -40 °C to +85 °C
operating conditions; low power, 3.3 V
operation, 5 V tolerant I/O
