Package B ONT SoC technology consists of five key elements:
•
GPON MAC
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 Gigabit Ethernet MAC addresses.
•
DSP interface
The Digital Signal Processor (DSP) provides voice processing for 2 POTS lines
with the 3-way calling. The DSP has a dedicated 64 kbyte instruction cache and
shares a 32 kbyte data cache with the Control Processor.
•
Control Processor
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 400 MHz.
•
Switch matrix
The Switch matrix provides an integrated data channel between the four GE
MACs, the GPON MAC, the MoCA 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.
The single-residence Gigabit Ethernet ONTs without POTS or RF video connections
use a SoC-based functional block that transmits Ethernet packets to either one, two,
or four RJ-45 Ethernet ports. These ONTs also feature fiber optic and power
connectors, as well as a reset button.
