OC-48 SONET/SDH Ethernet Mapper
TXC-06710
PRODUCT INFORMATION
DESCRIPTION
The EtherMap™-48 Device is a highly integrated, STS-48/STM-16
rate SONET/SDH VLSI device, for mapping of Gigabit/100BaseT
Ethernet and 8B/10B block encoded traffic like Gigabit Ethernet,
Fibre Channel, FICON, ESCON into SONET/SDH Transport. The
EtherMap-48 addresses Metro applications such as the transport of
switched Ethernet for point-to-point connections of aggregated
Ethernet and Packet traffic, and Storage Area Networks (SAN).
The EtherMap-48 SONET/SDH interface consists of one full duplex
STS-48/STM-16 channels, which can also operate at a 4xSTS-12/
STM-4 rate. The EtherMap-48 provides single OC-48 or Quad
OC-12 framing. There is full TOH/POH processing and monitoring,
along with full Virtual Concatenation and LCAS support.
The EtherMap-48 Ethernet interface consists of four 1.25GHz
SerDes for the 8B/10B clients, including Gigabit Ethernet, and
4xGMII interfaces for Gigabit Ethernet, lead-multiplexed with
24xSMII Fast Ethernet interface. Over-subscription for mapping
four Gigabit Ethernet streams into a single STS-48/STM-16 by
statistical multiplexing are supported via configuration and built-in
flow control mechanisms.
• Single STS-48/STM-16 or 4xSTS-12/STM-4 line-side
interfaces
• On-chip 622 MHz clock synthesis
• 4xSTS-12/STM-4 and STS-48/STM-16 Framing
• Transport Overhead Termination and Processing
• Supports contiguous Concatenation at STS-1 granularity
• Pointer tracking at AU-4-16c/AU-4-4c/AU4/AU3/TU3
levels
• Full Duplex cross connect at both STS-1-VC-3 and
TU-3-VC-3 granularity, with facility for Line and Terminal
side STS-1 Path level loopbacks
• Full Path Overhead Processing and Termination, at the
HO/LO Path Level.
• Retiming at HO Path Level (STS-1 through STS-48/48c
level)
• Ring ports, K1/K2 ports, TOH and POH ports for TOH/POH
Bytes
• Full support for HO Virtual Concatenation to ANSI T1.105/
ITU-T G.707/G.783 with or without LCAS (ITU-T G.7042)
• Terminal-side interfaces for 4x GMII interfaces (Gigabit
Ethernet with MAC) and up to 24x SMII Interfaces (100
Mbit/s Ethernet)
• Terminal-side Serial Data and Reference clock interfaces for
the 4x1.25 GHz SerDes for 8B/10B block encoded clients
• Provides Ethernet 100/1000 Mbit/s Framed PDU mapping
over GFP (ITU-T G.7041) or LAPS (ITU-T X.86)
• Provides transparent GFP mapping for standard 8B/10B
block coded clients, such as Gigabit Ethernet, Fibre Channel
(ANSI X3.230), ESCON (ANSI X3.296), and FICON.
• Provides configuration and Flow Control support for oversubscribed operation of Gigabit Ethernet (4xGigE into a
single OC-48) or Fast Ethernet clients
• Mailbox interface with API for device configuration with
higher level messages
• 2.5 V/3.3 V I/O, 1.3 V core
• 676-lead SFC Ball Grid Array package
