Note
(1)
High-speed Internet and video can either have their own HSI, or share the same HSI. If the HSI is
shared, an IGMP signaling channel is required for video.
3.3 Ethernet interface specifications
The Ethernet interface supports the following specifications:
• Ethernet ports are IEEE 802.3 and 802.3as compliant
• IEEE 802.1q, 802.1x port-based authentication, and 802.1p QoS classification
per Ethernet port
• Layer 3 DSCP-to-802.1p mapping to allow layer 3 CoS over the layer 2 network
• RJ-45 connector(s)
• full or half duplex operations
• auto-negotiation or manual setting by operator
• 10/100 Base-T or 10/100/1000 Base-T (depending on the ONT type)
Voice subsystem
ONT SoC-based technology provides a maximum of four POTS lines for voice
services and can support either H.248 (Megaco) or session initiation protocol (SIP)
signaling protocols. All POTS ports on an ONT must be configured to use the same
signaling protocol. Signaling protocols can not be mixed.
The following signaling protocols are supported:
• for ONTs with four POTS lines, two lines can have both 3-way and 2-way call
support, but the remaining two lines can support only 2-way calls
• support for G.711, G.726, and G.729 CODEC; the support for G.729 requires
reduced channel number with software upgrade
• fax per T.38 on POTS lines
ONTs are compatible with all existing subscriber voice equipment including analog
phones with tone or rotary dial capabilities, cordless phones, modems, fax machines,
and caller ID boxes (Type I, Type II, and Type III).
Data and IP video subsystems over Ethernet interface
Data and IP video services are delivered through the Ethernet cable interface. The
Ethernet interface connects the subscriber premises equipment to the GPON.
