The TD-W8951ND is a 150Mbps Wireless N ADSL2+ Modem Router.
The board seems to be similar to the ASUS DSL-N10: i.e. it has two SoC. One Trendchip (TC3162LE-LQ128G + TC3086-QFN64-EPG) for the ADSL part and a (Ralink:?:) for wireless:?: .
I can see a flash chip Winbond 25Q16BVS1G.
There are two EM638165TS-6G RAM chips: one near Trendchip SoC and the other one near the other SoC.
