Overview
The WRTU54-TM has an 8MB flash, 64MB RAM, Infineon WildPass ADM8668 SoC, Infineon Vinetic device for the two telephone ports, and GemPlus GemCore SIM Pro Smart Card Reader attached to the USB bus to read credentials from two SIM cards. It utilizes UMA/GAN. Basically all voice traffic is passed as GSM over an IPSec link to T-Mobile.
Hardware
Serial Port
JP2 is your standard Linksys 3.3v serial port at 115200 8N1. You'll need a level converter. The pinout is as follows:
1 - 3.3 VDC 2 - TXD 3 - RXD 4 - GND
USB2.0 Port
The SoC offers a single USB2.0 port, which is attached to the SIM card reader. The reader can be removed from the circuit and replaced with a USB port for Flash drives, etc. More info on USB here: HOWTO: Replace SIM reader with USB connector
Software
Das U-Boot boot loader with Linux kernel 2.4.31-ADM8668. Separate recovery kernel and rootfs in flash. rootfs is squashfs-2.2 with LZMA compression.
