I-211M-K and I-211M-L functional blocks

Package B ONT SoC technology serves as the main hardware block for all Package
B ONTs; see Figure 28-5.
Package B ONT SoC technology consists of six 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 GE MACs.
•
MoCA MAC
The Multimedia over Coax Alliance (MoCA) MAC supports the MoCA v1.1
specification set.
•
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.
