B-2404-P functional blocks

B-2404-P business ONTs transmit voice traffic to two RJ-11 POTS ports, Ethernet
packets to four RJ-45 Ethernet ports, and performs layer 2 Ethernet packetization and
de-packetization on up to four RJ-48C E1 ports.
In order to support four 10/100/1000 Base-T Ethernet ports, an Ethernet switch is
connected to the two GMII from the Ethernet MACs on the SoC. The Ethernet switch
provides IGMP packet replication and internal VLAN tagging to direct traffic to the
proper Ethernet port. Data and IP video services are delivered through the Ethernet
cable interface. The Ethernet interface connects the ONT to the PON.
A set-top box is required for the IP video service. The requirement for the television
set associated with the set-top box is that it must be able to receive and display analog
broadcasts on channel 3 or 4. The Ethernet port can be set to the following:
•
10/100/1000BASE-T auto
negotiation
•
10/100/1000BASE-T half duplex
•
10/100/1000BASE-T full duplex
•
10BASE-T auto-sensing
•
10BASE-T half duplex
•
10BASE-T full duplex
IP video service is supported using the Internet Group Management Protocol
(IGMP). The IGMP snooping function supports:
•
the ability to enable and disable IGMP per Ethernet port
•
the ability to age out multicast MAC addresses in the IGMP table
•
G.984.3 compliant multicast using a single GEM port-ID for all video traffic (as
mandated by G.984.3)
•
up to of 128 video multicast streams per device
The B-2404-P can terminate up to four DS1 or E1 links at the subscriber's premises,
and performs layer 2 Ethernet packetization and de-packetization using MEF-8 and
pseudo-wire PWE3 technology. TDM traffic is encapsulated using MEF-8
packetization before being transported across the GPON as layer 2 Ethernet.
Unstructured and fractional DS1 or E1 are supported.
The CES IWF packetizes DS1 or E1 traffic received at the RJ-48C port before it is
multiplexed with other Ethernet layer 2 data packets for transport upstream on the
GPON. MEF-8 is the packet payload format used. The packetization is removed
before downstream DS1 or E1 traffic from the GPON is sent to the DS1 or E1 lines
at the subscriber side.
