zNID 2400A Series Indoor GPON ONT: ZNID-GPON-2402A, 2403A, 2424A, 2425A, 2426A & 2427A


DZS’ indoor residential 2400A series GPON ONTs are designed for advanced triple-play deployments in Fiber-to-the-Home/Premise applications. The indoor models in DZS’ zNID product line of ONTs provide a lower cost alternative to outdoor ONT solutions. The small package contains many features including QoS, VoIP, and multicast video support. The series includes models with up to four 10/100/1000Mbps LAN ports, two POTS Voice FXS ports, b/g/n WiFi (with internal or removable external antennas) and an RF Video port, in a compact enclosure for indoor use.

Supporting industry standard SIP and MGCP voice signaling provides reliable voice services. DZS’ experience with packet voice ensures interoperability and support with a large number of soft switches. The four Ethernet ports can be separated into different services allowing the configuration of dedicated ports for IP video and data.

With wire-speed routing, a web UI for local management, and support for DZS’ CPE Management system, the DZS GPON ONT solution paired with the MXK OLT is an efficient way to extend bandwidth intensive services to the network edge using standard Ethernet frames.

The GPON 2400A series ONTs can be either wall mounted inside the home or placed freestanding on a desktop.
