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。; W/ }4 H+ Q3 |  g! X0 c
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5 p# W! T2 n1 a- @8 q2 J$ R
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- E" O$ @2 M# ~" u+ m
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.

* [$ Z4 d/ s9 ]- L: z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$ L8 Z  h, m- W4 a- b# J. L0 ?
