ONT Product Information Guide
Figure 19-3 Package M ONT and MDU hardware block
Package M ONT and MDU SoC technology consists of four 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 one GE MAC.
• 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 GE MAC, the
GPON MAC, the control processor, and the other integrated elements such as
flash memory, DRAM, and the local bus controller.
Package M ONTs can also interact with additional hardware components to support
functionality not provided by the SoC technology.
Single-residence Gigabit Ethernet ONTs are the only variation of Package M ONTs.
These Package M ONTs transmit Ethernet packets to one SFP port. These ONTs also
feature an SFP connector to connect directly to a residential gateway with an SFP
cage.
Figure 19-4 shows the functional blocks for an I-010S-P or an O-010S-P.
