摘要: 光網(wǎng)絡(luò)設(shè)備(Optical Network Terminal,ONT)是XPON網(wǎng)絡(luò)接入方案中的產(chǎn)品,是一種應(yīng)用在用戶端的光網(wǎng)絡(luò)終端,有GPON和EPON。介紹以PON ONU SOC為主控芯片的16線POTS ONT的硬件設(shè)計(jì)及遇到的問(wèn)題以及如何解決這些問(wèn)題。此設(shè)計(jì)是一款基于GPON(ITU-T G.984)標(biāo)準(zhǔn)并支持以太網(wǎng)和語(yǔ)音接口的ONT,適用于北美市場(chǎng),滿足NEBS1標(biāo)準(zhǔn)。本設(shè)計(jì)的特點(diǎn)是有16線的語(yǔ)音用戶接口和1個(gè)GE的接口,上聯(lián)是GPON,支持Dying Gasp且功耗低。

Abstract: (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.
Key words : ONT;GPON;BOSA;POTS;GE
