  • Supports IP-based voice, all forms of enterprise IP-based data traffic and all forms of enterprise IP-based video traffic

Included Highlights


The Tellabs 131W ONT supports Plain Old Telephone Services (POTS) analog voice over one RJ-11 connectors. This means that VoIP Softswitch or CLASS 5 based high quality voice service through one POTS line or VoIP access through one of three Ethernet interfaces can be utilized. Proven interoperability with major soft switch manufacturers. Interoperability certification has been completed with Metaswitch and BroadSoft.


Packet based interactive IPTV services including multicast video and video-on-demand is supported on the Tellabs 131W ONT. This is inclusive of IGMP v2 plus v3 proxy, and MAC level ITU 802.1p QoS standards for streaming IP video and IPTV content delivery.

Powering Options

Remote powering can be accomplished with 48V feed that can be connected at the rear of the ONT via a 2-wire phoenix style connector.

Mounting Choices

The Tellabs 131W ONT can be desktop or wall mount. In-wall mounting can be provided using standard dual or single gang electrical box. This ONT is also plenum rated for mounting in air handling spaces. It also supports industrial temperature ratings allowing both indoor and outdoor mounting locations. There are four holes in the ONT that extend through the faceplate to the back of the ONT and are used to secure the ONT into a standard dual or single gang electrical box.

Advanced IP and Ethernet

Tellabs 131W ONT offers industry-leading software-defined traffic management, security, provisioning and quality of service mechanisms. True enterprise advanced IP and Ethernet protocols are supported for ultimate LAN security, scalability and operational efficiencies.

Power over Ethernet (PoE)

With PoE functionality, the Tellabs 131W ONT connects to any Powered Device (PD) such as IP-Phones, IP-Camera, and other equipment that can be powered from the Ethernet port. Both IEEE 802.3af PoE and high-power PoE+ IEEE 802.3at, including Class-4 negotiations can be selected on per port basis. The maximum PoE power is 30 watts, spread across two Ethernet ports.

Centralized Management

All features and functionality can be defined in software and dynamically allocated, based on real-time needs. Being controlled by the Tellabs Panorama PON Manager helps speed installations and daily operations. Centrally controlled by the Tellabs Panorama PON Manager, the Tellabs 131W ONT supports auto-discovery mechanisms, can be quickly provisioned using global templates and profiles, and offers smart troubleshooting tools, all of which allow for speedy moves, adds and changes for everyday operations.
