EtherMap-12 Device
Ethernet into STS-12/STM-4 SONET/SDH Mapper
TXC-04212
FEATURES
• Eight 10/100 Mbit/s Ethernet ports, each using a SMII inter-
face
• Single 1000 Mbit/s Ethernet port, using a parallel GMII inter-
face (lead shared with SMII interfaces)
• Ethernet Management interface for control and configura-
tion of externally connected PHYs
• GMII Mux-mode allowing multiple concatenation groups
from one GMII
• Supports IEEE 802.3 flow control (Half and Full-duplex) and
management statistics (RMON) on 10/100/1000 Mbit/s
Ethernet ports (100 Mbps full-duplex only)
• Ethernet frame encapsulation/decapsulation protocols:
• ITU-T G.7041, Generic Framing Procedure (GFP)
• ITU-T X.86/X.85, Link Access Procedure SDH (LAPS)
• ITU-T Q.922, Link Access Procedure Frame Mode
(LAPF)

Bridging Control Protocol (BCP) support
• Transparent HDLC processing
• Performs mapping/demapping of encapsulated Ether-
net frames into/from Low Order Virtual Concatenated
• Payloads and High Order virtual and contiguous concate-
nated payloads
• Dynamic bandwidth allocation using LCAS (ITU-T G.7042)
for Low and High Order Virtual Concatenated payloads

DESCRIPTION
The EtherMap-12 is a highly integrated, STS-12/STM-4 rate
SONET/SDH device that provides mapping of 10/100/1000 Mbps
Ethernet traffic into SONET/SDH Transport structures.
The EtherMap-12 has on the Ethernet side, either Eight 10/100
Mbps SMII MAC interfaces or One independent 1000 Mbps GMII
MAC interface. Over-subscription is allowed for example in map-
ping One Gigabit Ethernet stream into either a single VC-4-
4c/STS12c SPE, multiple VC-4/STS-3c SPEs, or multiple VC-
3s/STS-1 SPEs is supported via configuration and built-in flow con-
trol mechanisms.
The STS-12/STM-4 front-end of the device is a standard byte wide
77.76 MHz Telecom Bus interface SONET processing includes Low
and High Order pointer tracking and retiming, Low and High Order
POH processing and performance monitoring along with complete
High Order and Low Order Virtual Concatenation with LCAS. Both
VT/TU and STS-1/VC-3 level non-blocking cross connects are
available for flexible data path grooming and switching. The device
operates from a 1.2V core and 3.3V/IO power supplies.
A fully functional Device Driver is available through TranSwitch
Applications Engineering.
APPLICATIONS
• SONET/SDH add/drop and terminal multiplexers
• Multi-service access platforms
• IP DSLAMS
• CPE access platforms
• Wireless backhaul multiplexors
