16线POTS ONT硬件设计

The design of 16 line POTS ONT

光网络设备(Optical Network Terminal,ONT)是XPON网络接入方案中的产品,是一种应用在用户端的光网络终端,有GPON和EPON。介绍以PON ONU SOC为主控芯片的16线POTS ONT的硬件设计及遇到的问题以及如何解决这些问题。此设计是一款基于GPON(ITU-T G.984)标准并支持以太网和语音接口的ONT,适用于北美市场,满足NEBS1标准。本设计的特点是有16线的语音用户接口和1个GE的接口,上联是GPON,支持Dying Gasp且功耗低。

(Optical network terminal,ONT)is the production of XPON network access.It’s an optical network terminal applied at the user end,including EPON(Ethernet Passive Optical Network)and GPON(Gigabit-Capable Passive Optical Networks).This paper introduces the design of 16-line POTS with PON ONU SOC as the main control chip,the problems encountered and how to solve them.It is an ONT based on GPON(ITU-T G.984)standard and supports Ethernet and voice interface.It’s applicable to north American market and meets with NEBS1 standard.The design features a 16line voice user interface and one GE interface,its uplink is GPON,supports the Dying gasp and has low power consumption.
