ONT SoC technology consists of five key elements:

The Gigabit Passive Optical Network Media Access Control (GPON MAC)

element on the SoC terminates the GPON interface using an optical diplexer. This

interface supports GPON as described in G.984.3 (GPON TC Layer) ITU

specification.

Ethernet MAC

The SoC provides up to four GE MACs.

The Digital Signal Processor (DSP) provides voice processing for 2 POTS lines

with 3-way calling. The DSP has a dedicated 64 kbyte instruction cache and

shares a 32 kbyte data cache with the Control Processor. It provides up to 4

network processor cores, each at 800MHz.

The Control Processor features an integral memory management unit that

supports a dedicated 64 kbyte instruction cache and shares a single 32 kbyte data

cache with the DSP. The Control Processor and DSP also include a single channel

Data Management Application (DMA) controller with a 4 kbyte read ahead

low-latency Dynamic Random Access Memory (DRAM) access port. The

processors typically run at 500 MHz.

Switch matrix

The Switch matrix provides an integrated data channel between the four GE

MACs, the GPON MAC, the DSP, the control processor, and the other integrated

elements such as flash memory, DRAM, and the local bus controller.

These ONTs can also interact with additional hardware components to support

functionality not provided by the SoC technology.
