The zNID-GPON-94xx ONTs are designed for business applications. These ONTs provide up to eight Voice ports and eight 10/100/1000bT LAN ports, plus a ninth 10/100/1000bT LAN port for connecting an auxiliary device such as a Wi-Fi access point or video camera. In addition to the voice and data services, the 94xx ONTs provide up to 8 T1/E1 ports. The T1/E1 data is transported over the packet network using Pseudowire Emulation Edge to Edge (PWE3) technology. The PWE3 technology allows voice, Ethernet and the TDM traffic to be transported over the GPON link. These ONTs support multiple TDM clock recovery methods (Adaptive, Synchronous, Differential) to provide accurate clock recovery in a variety of network configurations. The unit also supports IEEE 1588v2 timing recovery. Each Voice port, LAN port, and T1/E1 port is individually controlled, and can be assigned to a specific customer. A customer can have as many Voice, LAN, or T1/E1 connections as needed. Unique VLANs are configured per customer to ensure full isolation of each customer’s traffic. All 9000 series ONTs provide the same voice features found on the 4200 series of Single Family Unit (SFU) ONTs. SIP-PLAR signaling is supported for connection via Zhone’s Voice Gateway to traditional Class 5 TDM switches, while both MGCP and SIP are supported for direct connection to a VoIP Softswitch. This flexibility allows Zhone’s 4200 and 9000 Series ONTs to work in nearly all Telco networks, with interoperability support for a broad array of Softswitches. All LAN ports are capable of suppling Power over Ethernet (IEEE 802.3at compliant) making this also an ideal product for applications such as video surveillance.
