  “Can you please check your ont compliance?” “Please check the ONT Specification in attached file.” Usually, some of our global customers will bring a lot of questions regarding to the list of features in their PON ONT equipment requirement. Based on actual sales experience, our team is sharing a list of features, which are most wanted in a PON ONT terminal project.

 

Overview

  ONT should be Equipped with ITU-T G.984 compliant 2.5G Downstream and 1.25G Upstream GPON interface, supports the full Triple Play of services including voice, video, and high speed internet access service. Compliant with standard OMCI definition, ONT should be manageable at remote side and supports the full range FCAPS functions including supervision, monitoring and maintenance. ONT should also support TR069 management protocol.

 

data

 

The GPON ONT is delivered with four 10/100/1000 Base-T Ethernet data interfaces, supporting:

 

Auto-negotiation and MDI/MDIX auto-sensing.

Built-in layer-2 switch

Advanced data features such as VLAN tag manipulation, classification, and filtering

802.11 b/g/n/ac WLAN interface (Bridge mode Wifi)

Dual Band Wi-Fi (2.4GHz & 5GHz)

High Gain MIMO Antenna

Multiple Wi-Fi SSID (up to 4) – Each mapped to different LAN Port/ GEM Port

USB 2.0/3.0 storage

 

Voice

The ONT is delivered with up to two POTS interface ports for carrier-class voice services, supporting:

 

5 REN per line, balanced Ring at 55V RMS, DTMF dialing

Multiple voice codec

Supporting Echo Cancelling, VAD, CNG

Supporting static or dynamic jitter buffer

Various CLASS services – Caller ID, Call Waiting, Call Forwarding, Call Transfer, etc.

SIP (RFC3261)

 

Support multiple country-profiles

 

Video

The ONT should support video contents delivered in the form of data (by multicast or unicast).

 

In case where multicast technology is used for delivering video contents through data channel, the ONT supports the dedicated multicast GEM port on the Downstream. So the video contents are received and processed by all the ONTs through the unified channel and this greatly improves the bandwidth efficiency.

 

  In addition, the ONT supports IGMP snooping function to be applied for further optimization. When IGMP snooping is enabled, the ONT monitors the member joining and leaving activities at the Ethernet service port, and then selectively delivers the multicast streams.
