Notes
(1)
These items are determined by the country-specific VoIP configuration XML file. The values
specified are for ANSI deployments.
(2) While the maximum ringing capacity for all ONTs is five REN per POTS line, some ONTs can support
more than one POTS line at a time. For MDUs and business ONTs, the maximum ringing capacity is
three POTS lines with a five REN load ringing simultaneously. For indoor ONTs, the maximum
ringing capacity is two POTS lines with a five REN load ringing simultaneously.

Note —
For ONTs that have SoC technology on-board in a
two-Ethernet port device, only one Ethernet UNI port at a time can be
configured for IPTV and multicast streams.
