zNID 2728A1 Indoor Active Ethernet ONT


Introducing the newest mix of style and technology – the Zhone 2728A1 Indoor GE ONT. Dual-band 802.11ac WiFi capability combines with a stylish table-top finish to bring next-generation connectivity and best-of-class performance to Fiber-to-the-Home/Hotel deployments.

Seven internal high-gain antennas enable concurrent dual-band radios (2.4 and 5.8GHz) WiFi radios to independently connect multiple users and devices simultaneously, including older 802.11b/g/n devices. Its 3×3 and 4×4 MIMO antenna design provides superb WiFi throughput and coverage. The latest technology combined with 802.11ac (5.8GHz) makes delivering reliable Multicast IPTV services over WiFi a reality.

The 2728A1 GE ONT is ideal for providing premium WiFi services in large homes, home theaters, and hotel guest and conference rooms facing a variety of laptops and mobile devices.

The 2728A1 GE ONT provides four 10/100/1000Mbps LAN ports, two FXS Voice ports, and one USB port. The four Ethernet LAN ports can be separated into different services allowing the configuration of dedicated ports for IP video and data.

The 2728A1 GE ONT sits upright and its attractive, modern enclosure requires a small footprint making it equally at home on a living room bookshelf or as a polished accessory in high-end commercial accommodations. An easy to use wall-mounting bracket is also included. Simplified and easy-to-read indicators allow for quick trouble-shooting even with no internet connection to avoid unnecessary cable-pulling and power-cycling. Hospitality installations will appreciate the guest-friendly indicator modes (Day, Night, Off). Extensive diagnostics in the ONT (run locally on the ONT or remotely from the NOC) reduce service call disruptions.

The supported industry-standard SIP and MGCP VoIP signaling provides reliable voice services. Zhone’s experience with packet voice ensures interoperability and support with a large number of soft switches and with the ability to tailor the VoIP solution by selecting from a list of over 30 countries.

Flexible management means the 2728A1 GE ONT may be provisioned using the same intuitive and easy-to-navigate Web interface and CLI as the Zhone 2400, 2600, 2800 and 4200 Series ONTs, as well as through USP (Unified Service Provisioning), the Zhone Network Management System (ZMS), or using a TR-069 compliant ACS. Software upgrades and configuration backups can be handled automatically by the ZMS using the CPE Manager feature.
