AONT 1532




The AONT-1532 has been optimized for residential homes for providing triple play Broadband services that also require RF video.

Advanced High Bandwidth GPON technology

The AONT-1532 is fully FSAN (ITU-T G.984) compliant 2.488 Gbpsdownstream and 1.244 Gbps upstream GPON systems.

Quality of Service

The AONT-1532 supports extensive QoS features, including 802.3x -flow control, DSCP to 802.1p mapping, upstream congestion control, and downstream traffic scheduling for premium or time sensitive content. Intelligent and robust buffer and queue management for Ethernet traffic, with individual prioritized queues, ensures that tiered service offerings based on different bit-rates and QoS can be readily supported.


The AONT-1532 contains both wire-speed L2 switch and L3 routing gateway with port forwarding, NAT and NAPT address translation, built-in PPPoE support for HSI, and an integrated stateful packet inspection (SPI) firewall with a configurable access control list (ACL) and application-level gateway (ALG). Support for VPN (L2TP, PPTP and IPSec) pass through is also provided. Included as part of the gateway function are DHCP client, DHCP server and DNS server for IPv4 and IPv6.


The AONT-1532 comes with the latest security features, including MAC address spoofing protection, MAC/IP address port binding, per-port access control list (ACL) based on port, MAC address and Ether-type, DoS prevention and wireless encryption protocols such as WEP and the more secure WPA/WPA2.
