Overview

The EtherMap™-12 is a highly integrated, STS-12/STM-4 rate SONET/SDH devic.

  • Eight 10/100 Mbit/s Ethernet ports, each using a SMII interface
  • Single 1000 Mbit/s Ethernet port, using a parallel GMII interface (lead shared with SMII interfaces)
  • Ethernet Management interface for control and configuration 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)
  • IETF RFC2878, Point-to-Point Protocol (PPP) with Bridging Control Protocol (BCP) support
