V.42/MNP/Buffer Configuration Options

*V42bis Compress: Enable

Nxt Enable Disable

V.42bis Compression. Enables or disables V.42bis data compression.

Enable ± Data compression operates in both the transmit and receive directions. This is the recommended setting for all applications.

Disable ± V.42bis data compression is disabled. This is rarely needed because V.42bis data compression does not cause data expansion for compressed data.

The factory default is Enable.

NOTE: This configuration option is only available if Error Control Mode configuration option is set for V42/MNPorBfr or . V42/MNPorDsc.

AT command equivalent is ″ Hn.

*MNP5 Compress: Enable

Nxt Enable Disable

MNP5 Compression. Determines if the modem uses MNP Class 5 data compression. It can be set independently of V.42bis data compression. Online changes do not take effect until a disconnect occurs.

The factory default is Enable.

NOTE: This configuration option is only available if Error Control Mode configuration option is set for V42/MNPorBfr, V42/MNPorDsc, MNP or Buffr, or MNP or Disc.

AT command equivalent is %Cn.

*EC Negotiat Bfr: Disable

Nxt Disable Enable Disab&Switch

Error Control Negotiate Buffer. Determines if the answering modem buffers the data that it received from the remote modem during an interval in which the modem attempts to establish a connection using error control. Online changes do not take effect until a disconnect occurs.

Disable ± Data is not buffered during the link negotiating (handshaking) sequence.

Enable ± Data is buffered while the link is being established. Initialization data is not passed on the DTE during the handshaking sequence.

Disable and Switch ± Data is not buffered during the handshaking sequence. However, when the modem receives an error control fallback character, it switches to Buffer mode. (See EC Fallback Char configuration option.)

The factory default is Disable.

AT command equiovalent is \Cn.

*This configuration option is only available if Async/Sync Mode is configured for Async. Refer to the DTE Interface configuration options group for more on Async/Sync Mode.
