Overview

"ACTIONTEC", "04404A", and "47-0045-2SA3" is silkscreened on the board populating this entry.

The two large radial capacitors in the power section appear to be Chemi-Con caps. Capacitors on the rest of the board are (at least) a mix of GEMCON, Y.J., and Fullcon caps.

The device uses Globespan GS7070 and GT3180 chips for the ADSL modem.

The Ethernet transformer is a Mag.Com PX-5111S.

The power adapter included with the unit may be an OEM AD-121AG (120VAC ~ 60Hz, 18W -> 12VDC, 1A). The modem's label specifies that it uses a 12V 1.2A PSU, however..
