Looks like we’re missing the transformer from the PSTN black port but it’s still active and the green port is inactive according to the manual. There are two metal cans, one for the DECT radio and one for something else labelled SC – which there are two more labels on the PCB, I can only assume it means “Special Circuit” or similar. The heatsink that’s on top of the main chip has been soldered down using what looks like a nail on the top left and some epoxy to hold it down, the heatsink has a foot print which could have been a bit bigger. The PCB date code is 14th week of 2014 so it’s pretty recent. We’ve got a MP9141ES and 2x MP1492 SMPS near the input jack, an UTC LD1117 LDO and we’ve got Lelon branded electrolytic capacitors, there is a outline in the middle of the PCB for a very large capacitor. There’s a small removable panel at the front which looks to be for a DECT cradle. It looks to be similar to the Thomson Gateway TG797.Ģ screws later and we’re in.
Once again this is another router which I haven’t heard of this brand before. Today we’ll be taking a look at the Technicolor TG797n v3 Router (Telstra branded), an ADSL2+ Wireless router with 1 gigabit WAN and LAN port, 3 10/100 ports, VOIP, DECT and 2 USB ports.
