zNID 2400A1 Series Indoor GPON ONT: ZNID-GPON-2424A1, 2426A1 & 2428A1


Introducing the newest mix of style and technology – the Zhone 2400A1 Series Indoor GPON ONT. Dual-band 802.11ac WiFi capability combines with a compact design to bring next-generation connectivity and best-of-class performance to Fiber-to-the-Home deployments.

Five internal high-gain antennas enable two radios (2.4 and 5.8 GHz) WiFi radios to independently connect multiple users and devices simultaneously, including older 802.11b/g/n devices.

The 2400A1 GPON ONT is ideal for providing WiFi coverage in homes, hotel guest and conference rooms facing a variety of laptops and mobile devices.

The 2424A1 GPON ONT provides four 10/100/1000Mbps LAN ports, two FXS Voice ports, and one USB port. The future-proof GPON optics include a WBF (wavelength-blocking filter) for coexistence with Next-Gen-PON ONTs. The four Ethernet LAN ports can be used to support any-port-any-service model, or separated into different services allowing the configuration of dedicated ports for IP video and data. Unique VLANs may akso be configured per user to ensure full isolation of each department’s data traffic. The 2426A1 GPON ONT adds an 2.4G WiFi. The 2428A1 GPON ONT has the most comprehensive feature set in the 24XXA1 family supporting 4xGE, 2X POTS, 2.4G and 5.8 WiFi.

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 2400A1 GPON ONT may be provisioned using the same intuitive and easy-to-navigate Web interface and CLI as the Zhone 2400, 2600, 2700, 2800 and 4200 Series ONTs, as well as through GPON-standard OMCI, 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.
