Carrier Loss Duration (modemCarrierLossDuration)
The number of seconds the carrier signal must be missing before the connection is considered lost.
Retrain(modemRetrain)
Enable the modem to monitor line quality and request a fallback or retrain for poor quality and a fall forward
for good quality.
•
none(0)—do not allow modem to retrain, fall forward, or fall back.
•
ratrain(1)—all modem to retrain or fallback if the line quality is poor, or fall forward to a faster speed if the
line quality is good.
•
fallForwardFallBack(2)—allow the modem to fallback to a slower speed if the line quality is poor, or fall for-
ward to a faster speed if the line quality is good.

Protocol (modemProtocol)
Assigns the error correction protocol for use with the modem. The following options are available:
•
direct(0)—no error correction will be used
•
requestV42(1)—enables v.42 error correction. If this is selected, the modem will either negotiate for v.42
error correction or—if v.42 correction is not available will not use any error correction.
•
requireV42(2)—V.42 error correction is mandatory, otherwise disconnect.
Compression (modemCompression)
Assigns the data compression protocol to use with the modem. This setting is in effect only when v.42 error
correction is active.
•
direct(0)—no compression will be used.
•
requestV42bis(1)—enable v.42bis data compression. If this is selected, the modem will negotiate for
v.42bis, and if it is not available, will use no compression.
