Business ONT
The business ONT is suitable for small business applications and provides voice,
data and IP video, and optional RF video services to subscribers and supports CES
DS1 or E1 connections at the business premises. The business ONT enclosure is
environmentally hardened for exterior installations. An external –48 V dc 50 W UPS
with backup battery is offered for use with the business ONT.
The business ONTs provide a single entry point for voice, data, and video services
at the subscriber’s premises and multiplexes DS1 and E1 traffic with Ethernet data
using MEF-8 for transport across the GPON. Each business ONT supports the
following:
• GEM mode support for efficient IP/Ethernet service traffic transport
• one GPON interface capable of 1.244 Gb/s upstream and 2.488 GB/s downstream
line rates as per G.984.3 using an SC/APC connector
• 1490 nm wavelength downstream, 1310 nm wavelength upstream, and optional
1550 nm downstream for RF video overlay
• integrated diplexer for ONTs supporting POTS and data
• integrated triplexer for ONTs supporting POTS, data, and the optional RF video
and/or MoCA service
• one 10/100/1000BASE-T MACs with GMII/RGMII interface providing Ethernet
services for IPTV, data, and VoIP
• eight POTS lines for connecting phones to VoIP services
• one RF video coaxial interface (not supported on all units)
• two DS1 or E1 interfaces supporting structured, unstructured, or fractional
services
• serial RS-232 craft interface
• external power and alarms
• optical budget of 28 dB (without FEC) and an Rx optical sensitivity of -27 dB
• PON reach capacity of 18.6 miles (30 km)
• full 100BASE-T throughput upstream and downstream simultaneously
• packet fragmentation support for packet sizes above 1500 MTU
• loop start
• G.984.3-compliant Dynamic Bandwidth Allocation (DBA)
• G.984.3-compliant Advanced Encryption System (AES) with operator
enable/disable per port-ID level
• G.984.3-compliant Forward Error Correction (FEC) for longer reach upstream
and downstream
• G984.4, G.983.2 revised compliant OMCI interface for ONT management and
provisioning
EMS
The EMS software system use GUI interfaces to provide element management
functions for the OLTs and ONTs.
