Receive Data. The RD LED flashes when data is being received (on for a space,

off for a mark). Data signals received from the remote MT5600ZDXV are

presented on this line. When no carrier signal is being received (pin 8

negative), this line will be forced into a marking condition. The RECEIVE (RD)

LED indicates the status of this signal.

Carrier Detect. This LED lights when a valid carrier signal from another modem

is detected.

56K. This LED is lit when connected to an ISP-type K56flex server. The actual

connection speed is contingent upon server capabilities and line conditions.

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

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

that at speeds lower than a V.32 bis connection, the MT5600ZDXV speed LEDs

remain unlit.

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

MT5600ZDXV wants the phone line to do something (i.e., dial or answer a

call). This LED is also lit when the MT5600ZDXV has achieved on-line status.
