Description

 

 

 

 

Sync Idle

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.

 

=Mark

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.

 

:Char

Applies to V.25bis, and LPDA2 ACUs.

 

 

If the modem is configured forV.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.

 

 

 

 

V25 Resp

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.

 

=V25bis

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.

 

:V25rate

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.

 

:VALOnly

The modem sends a VAL message when the modems switch to data mode.

 

V25 Resp:

The modem does not send a message to the DTE.

 

 

 

 

LPDA2 Addr

Lets you select the modem’s address. (See Chapter 2 of the 326X Series Modem Reference

 

 

Guide for details.)

 

LPDA2 ID

Allows the modem type to be returned in the data field response field.

 

=326X

Sends 3260 in data response.

 

:7855

Sends 7855 in data response.

 

 

 

 

LPDA2 Det

 

 

=Enab

LPDA2 commands are recognized in the data stream and the commands are processed.

 

:Disab

LPDA2 command frames are not recognized as commands.

 

 

 

TELCO

DL TX Level

Displays the modem’s dial line transmit level, which is set for your country’s requirements.

OPT’S

 

 

 

=0 to -15

The modem is set to transmit at a level in the 0 to -15 dBm range.

 

LL TX Level

Displays the modem’s leased line transmit level, which is set for your country’s requirements.

 

=0 to -15

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.

 

 

 

Gray shading indicates country-specific options. See Appendix C for your country’s options.
