| 説明 | The other complicated PCB in the unit contains the modem transmit and receive filters -- rather oddly for a unit of this data the latter uses 4 pot core inductors (up the left edge of the board). Also on here are the drivers for the line control relays and the amplifier for the built-inspeaker (not shown, it's fitted to the top cover). |
