28 LED to indicate speeds between 16,800 and 26,400 bps (see
table). It lights together with the 96 LED to indicate a speed of
12,000 bps.
9600 bps. The 96 LED lights when the modem connects at 9600
bps. If no speed LED lights, the modem is operating at less than
9600 bps.
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.
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.
Error Correction (V.42). The EC LED lights continuously when
the modem is in error correction mode, and blinks when compres-
sion is activated.
Fax. The FX LED lights when the modem is in fax mode.
Note: When you turn on the MT2834ZDX, 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 MT2834ZDX is 28,800 bps
(33,600 bps for the ZDXb) 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 9600 bps, all speed LEDs remain off after the connection is bro-
ken, even though the modem is still turned on.
