<b>Indoor Gigabit zNID</b>
<b>Overview</b>
The zNID-GE-22xx series of indoor ONT's provide an ideal solution for FTTH deployments. The indoor ONTs are standards-based CPE designed for advanced triple-play deployments. The device provides for many features such as QoS, multicast video, and voice. The ONT is designed for high performance applications. The gigabit interface uses SFP's for the ultimate in flexibility. The SFP can be either copper or optical. A wide range of Gigabit SFPs are available which support distances from 10 to 60 km.
The zNID-GE-2244 model has four voice ports, and the 2284 model has eight voice ports. Each model has four Ethernet ports that can be configured for bridging or routing. All Ethernet ports support full VLAN priority and QoS.
<b>Voice Features</b>
The zNID provides voice service with either 4 or 8 voice ports on the unit. The zNID uses SIP or MGCP. All the major voice features are supported. This includes features such as three-way-calling, caller ID, distinctive ringing, T.38 fax, and V.90 modem.
<b>Gateway Features</b>
The zNID is a full-featured gateway with integrated DHCP server, ALG's, NAT Router, PPPoE Client, scheduling, comprehensive logging, and more. The zNID product line implements a very flexible QoS allowing the service provider to guarantee that services are being prioritized correctly and the end-user is getting the Quality of Experience that is expected.
The indoor zNID is designed for high performance applications. It features one Gigabit Ethernet port and three Fast Ethernet ports, in addition to the 4 or 8 voice ports.
The zNID has full VLAN support with QoS. The packets in the VLANs are prioritized based on the IEEE 802.1p priority bits. In addition, each VLAN can be rate limited.
The zNID supports prioritization at the higher layers through the use of the Diffserv bits (RFC2474, RFC2475).
<b>Management</b>
The zNID has intuitive Web and command line interfaces. The zNID is also managed by the Zhone Network Management System (ZMS), using SNMP. Software upgrades and configuration backups can be handled automatically by the ZMS using the CPE Manager feature.
