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8 L# q- Z7 l) C& j3 d

VOIP:LE9530CETC6 u# H9 f; {: G3 S6 s5 Q
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.

6 {, ^. q( {' q; w5 d5 {3 e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
 楼主| 发表于 2013-1-18 10:00:28 | 显示全部楼层
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
