GPON ONT M 28X2 Houston

To deliver triple-play services to the subscriber in Fiber-to-the-Home or Fiber-to-the-Premises application, the GPON ONT M-28X2 for SFU (Single Family Unit) incorporates interoperability, key customers’ specific requirements and cost-efficiency

Equipped with ITU-T G.984 compliant 2.5G Downstream and 1.25G Upstream GPON interface, the M-28X2 ONT supports the full Triple Play of services including voice, video, and high speed internet access.

Compliant with standard OMCI definition, ONT M-28X2 is manageable at remote side and supports the full range FCAPS functions including supervision, monitoring and maintenance.

Services

Data

The M-28X2 ONT is delivered with up to four 10/100/1000 Base-T Ethernet data interfaces, supporting:

• Auto-negotiation and MDI/MDIX auto-sensing
• Data transferring at wire-speed for all packet size
• Built-in layer-2 switch
• Advanced data features such as VLAN tag manipulation, classification, and filtering

Voice

The M-28X2 ONT can optionally be delivered with up to two POTS interface ports for carrier-grade voice services, supporting

• 5 REN per line, balanced Ring at 55V RMS, DTMF dialing
• Multiple voice codec
• Echo Cancelling, VAD, CNG
• Various CLASS services - Caller ID, Call Waiting, Call Forwarding, Call Transfer, etc.
• SIP (RFC3261)
• MEGACO v2 (H.248)
• Common architecture, drop-in replacement

To enable VoIP access, the M-28X2 ONT also supports interfacing external IAD box or Home Router with voice capability through the Ethernet Interface.

Video

The M-28X2 ONT supports 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.
