ONT SoC technology consists of five key elements:
•
GPON MAC
The GPON MAC element on the SoC provides the GPON interface to the TC
layer via the optical diplexer or triplexer (if using RF video). This interface
supports the FSAN standards compliant GEM mode transport and provides AES,
FEC, and data fragmentation functionality over the GPON as described in
G.984.3 (GPON TC Layer) ITU specification.
•
Ethernet MAC
The SoC provides an Ethernet PHY device (either 10/100BaseT or
10/100/1000BaseT) between the GMII interface and the RJ-45 port.
•
Digital Signal Processor (DSP) interface
The DSP provides voice processing and has a TDM interface to the
CODEC/SLIC devices.
•
control processor
The control processor manages functions related to OMCI, IGMP, VoIP, and
Ethernet services.
•
SoC bridge
The SoC bridge provides an integrated data channel between the Ethernet MAC,
the GPON MAC, the DSP, the control processor, and the other integrated
elements such as flash memory, SDRAM, the local bus controller, and the
DUART interface to the craft port if used.
