Gigabit Ethernet to SONET OC-48 Multiplexer
Features | Block Diagram | Ingress | Egress | 
Description
The GEOS-2 IP core multiplexes 2 channels of GE traffic into a single Packet over SONET (POS) stream, using frame-mapped GFP (Generic Framing Procedures). The GEOS-2 core is designed to interface with a Dual-Port Capable Gigabit Ethernet MAC (PMC-Sierra PM3386 S/UNI® - 2x1GE) and a 2.488Gbit/s SONET/SDH Framer Device (PMC-Sierra PM5381 S/UNI® 4x622), using POS-PHY Level 3 cores.
Features
- Supports up to OC-48 bandwidth
- Multiplexes 2 ports of Gigabit Ethernet traffic into SONET
- Configurable destination port address
- Complies with Frame Mapped Generic Framing Procedures from ITU-T
- A Link Layer function
- Provides GbE Traffic Statistics per port
- Plug & Play with POS-PHY Level 3 cores for variety of system solutions with different bandwidths
- Optimized for integration with a 2-Port Gigabit Ethernet MAC using POS-PHY Level 3 cores
- Encrypted Netlist available
- Available on Altera Cyclone EP1C20
Ingress: Ethernet-to-SONET Data Flow
- Controlled by ESMUX module
- Automatic generation of GFP header to packet w/ destination port ID
Egress: SONET-to-Ethernet Data Flow
- Controlled by SEDEMUX module
- De-multiplexes traffic from SONET side into 2 GE ports
- Routes packets to their corresponding ports
