V.34. This LED is lit when the modem is connected in V.34 mode.

V.32bis. This LED is lit when the modem is connected in V.32bis mode.

Note at speeds lower than a V.32bis connection, the

MultiModemZDX speed LEDs remain unlit.

Off Hook. The condition of Off Hook indicates to the central

office that the MultiModemZDX wants the phone line to do some-

thing (i.e., dial or answer a call). This LED is also lit when the

MultiModemZDX has achieved on-line status.

Terminal Ready. When TR is lit, the MultiModemZDX can

answer an incoming call. This signal (TR or DTR) provides a means

for the terminal or computer to control the MultiModemZDX's

connection to the communications channel. A high DTR signal is

required by the MultiModemZDX to be able to communicate. The

state of the TR LED matches that of the DTR circuit on pin 20 of the

RS232/V.24 interface.

Error Correction. This LED is lit when the modem is set for V.42

error correction, and flashes on and off when data compression

is activated.

Fax. This LED is lit when the modem is connected in Fax mode.
