无线：BCM43217KMLG
VOIP芯片:LE9530CETC
内存：NANYA NT5TU32M16DG-AC 128MB
FLASH：NAND256W3A2BN6E 256M SLC

CPU：BCM6828FKFBG 没查到资料不知道是多少主频的。
无线部分：BCM43217KMLG 采用内部双天线隔了1墙的笔记本信号只掉1格感觉还不错。
外部天线是装饰。不过可以自己加。加了就是3天线了。
内存：NANYA NT5TU32M16DG-AC 64X16=1024bit=128MB DDR2 内存基本来说够用了。
拆开散热器的 CPU：BCM6828FKFBG 不知道哪里能查到资料
不过BCM的方案网络稳定性还是比较好的。而且估计以后会像BCM6358猫那样出现不少第三方功能强大的固件。
EPON 光模
供电部分做工
交换模块和主板版本号。其中第4的LAN口为1G接口。
TTL 和JATG接口
这个要顶 2013新款RG2000-CA 补充下BUG内存应该是64MB。不小心吧换算公式记错了。应该是 32X16/8=64MB
FLASH 换算回计算机上的MB来也是32MB的 继续补充 CPU：BCM6828FKFBG 国外论坛看了下听说是500-600MHZ 双核心网络处理器。
是BCM6818 的升级版。估计是提高了频率的版本就不知道稳定夏天到了怎么样。反正冬天进WEB看
CPU温度监控显示的是35度。比老版采用6818 的中兴F460好像要高点。

VOIP:LE9530CETC
The Le9530 Dual Ringing SLIC device is a dual-channel device optimized to provide battery feed, ringing, and supervision on voice loops found in short-loop VoIP applications. This device is optimized to interface to the Broadcom BCM3378/3380/3382 and BCM6816 devices, or a similar codec. The Le9530 device operates independently from a single, user-adjusted battery and a +3.3 V VCC per channel. Each channel provides forward and reverse battery feed, voice transmission, power ringing, an ultra low-power scan state, ground start (Tip open), and a disconnect state. A test load switch is also included to support integrated test algorithms.

目前只有这个。本来是选新版中兴F460的。不过师傅拿来对比穿墙无线信号。笔记本上掉了2格。这个也就只掉1格。然后这个CPU稍微要比中兴的强点。双核心500-600 MHZ。另外就是无线部分也是用的BCM 270MHZ的芯片。手机连接上比螃蟹芯片要稳定不少。而且考虑到全BCM芯片的方案后期国外的无限制固件好刷些。 你那有没F460固件呢 另外提供个第3方GEPON 固件 的下载地址 大家一起研究。准备校对好了。刷采用BCM6228 支持H248VOIP方案的无限制FW。彻底摆脱电信控制
