Description
Applies to synchronous applications only (direct synchronous or SDC operating modes). Your
modem sends Marks or Characters on EIA/TIA 232-D Pin 3 (V.24 Circuit 104) to the DTE when
it has no messages to send.
Modem sends continuous Marks (or one bits) on EIA/TIA 232-D Pin 3 (V.24 Circuit 104) to the
DTE when it has no messages to send.
Applies to V.25bis, and LPDA2 ACUs.
If the modem is configured for V.25bis and V25Form=Charsync, it sends a continuous stream of
SYN (synchronizing) Characters on EIA/TIA 232-D Pin 3 (V.24 Circuit 104) when it has no
messages to send. If V25Form=Bitsync, it sends continuous flags (7E hexadecimal) when it has
no messages to send.
If the modem is configured for LPDA2, it sends continuous flags (7E hexadecimal) when it does
not have a message to send.
When using the V.25bis ACU, the modem always indicates a valid connection after the local
modem and remote modem switch to data mode. You can receive an indication of call progress
at your DTE. The V25 Resp option chooses the response you receive.
The modem sends a VAL message upon receipt of the dial command and a CNX message once
an answer-back tone is received from the remote modem.
The modem sends a VAL message upon receipt of the dial command and a CNX message
followed by the data rate once the modem switches to data mode.
The modem sends a VAL message when the modems switch to data mode.
The modem does not send a message to the DTE.
Lets you select the modem's address. (See Chapter 2 of the 326X Series Modem Reference
Guide for details.)
Allows the modem type to be returned in the data field response field.
Sends 3260 in data response.
Sends 7855 in data response.
LPDA2 commands are recognized in the data stream and the commands are processed.
LPDA2 command frames are not recognized as commands.
Displays the modem's dial line transmit level, which is set for your country's requirements.
The modem is set to transmit at a level in the 0 to -15 dBm range.
Displays the modem's leased line transmit level, which is set for your country's requirements.
The modem is set to transmit at a level in the 0 to -15 dBm range.
Adjustable Transmit Levels—V.34 Modulation Mode
In the V.34 modulation mode, the local and remote modems negotiate a transmit level (for the
dial/leased line) during the training sequence. This allows the modems to select the lowest
possible transmit level in order to maximize the signal to echo level in the receiver. A typical
range for the reduction of the transmit level is 0 to -14 dBm.
NOTE: Although the modem negotiates a transmit level that may differ from the rate indicated
for your country, the front panel DL TX and LL TX Levels options remain the same. The CQMS
parameter, Tx Level, however, displays the actual transmit level in use for a connection.
