3 Features

Note: Although the modem can connect at lower than V.32bis speeds, no speed indicator lights during the connection.

OH Off-Hook.The OH LED lights when the modem is off-hook, which occurs when the modem is dialing, online, or answering a call. The LED flashes when the modem pulse-dials.

TR Terminal Ready. The TR LED lights when a datacomm program initializes the modem. It means the modem is ready for an outgo- ing or incoming call. It goes off when the datacomm program disconnects the COM port. When it goes off, a connected modem will disconnect. The state of the TR LED matches that of the DTR circuit on pin 20 of the RS-232C/V.24 interface.

EC Error Correction (V.42). The EC LED lights continuously when the modem is in V.42 error correction mode, and blinks when com- pression is activated.

FX Fax. The FX LED lights when the modem is in fax mode.

Note: When you turn on the modem, the speed lights flash briefly as the modem does a self-test, then the LED for the default modem baud rate lights. The default rate for the modem is 56K bps unless you select and store another baud rate. After a call, the LEDs for the connection’s baud rate remain lit until another call is made or the modem is reset. If you connect at a rate under 14,400 bps, all speed LEDs remain off after the connection is broken, even though the modem is still turned on.
