Description
A dial call is always answered. As soon as the dial call is answered, the leased line connection
is dropped (with auto-answering, the leased line is dropped after the correct number of rings).
If training on the dial line fails, the modem returns to the leased line.
Auto Type
During answer-back tone, the modem attempts to negotiate a connection in the V.32
modulation mode. As soon as answer-back tone ends, if a V.32 tone has not been detected
during ABT, the modem attempts to negotiate a connection in the V.22bis modulation mode.
During answer-back tone, the modem attempts to negotiate a connection in the V.32
modulation mode. After sending answer-back tone, the modem continues to attempt to
negotiate a connection in the V.32 modulation mode. If unsuccessful, the modem tries to
negotiate a connection in the V.22bis modulation mode.
Blind Dial
Determines the time the modem waits before dialing; once time has expired, the modem dials
without waiting for a dial tone.
The modem waits 2 seconds before dialing.
The modem waits 4 seconds before dialing.
The modem waits the amount of time specified by S-Register 6 before dialing.
Break Handling
Controls how the modem handles the break signal in reliable and auto-reliable data modes.
Break signals are sent to the DTE for the duration specified in S-Register 97.
The modem uses destructive and expedited break handling. It passes the break to the remote
site immediately and deletes all data from its buffers. NOTE: Destructive breaks reinitialize
data compression tables for MNP-5 and V.42bis.
The modem uses nondestructive and expedited break handling. It passes the break to the
remote site immediately without deleting data from its buffers.
The modem uses standard break handling. It passes the break to the remote site in sequence
with any transmit data from its buffers.
Answer/Originate Mode
The modem operates as an originating modem in a manual answer/dial application.
The modem operates as an answer modem in a manual answer/dial application.
The signal from the DTE on EIA/TIA 232-D Pin 11 determines whether the modem is in
answer or originate mode. If the signal is off, the modem is in originate mode; if the signal is
on, the modem is in answer mode
The modem configures itself as an originating modem after auto-answering a call. In leased-
line operation, the modem functions as if it is set to originate calls. NOTE: The functions
provided by this setting only apply when the modem auto-answers.
DCD Loss Disconnect
The modem will not disconnect due to loss of carrier.
The modem hangs up if it loses carrier for 3 seconds.
The modem hangs up if it loses carrier for 7 seconds.
The modem checks the value stored in S-Register 10 to determine when it disconnects due to
loss of carrier. See the "S-Registers" section in Chapter 5 for more information.
