100722A Conexant 3-47
3.2.5.9 -K - MNP Extended Services
Enables or disables conversion of a V.42 LAPM connection to an MNP 10 connection. The parameter value, if valid, is written
to S40 bits 0 and 1.
Syntax
-K<value>
Defined Values
<value> Decimal number corresponding to the selected option.
0 Disables V.42 LAPM to MNP 10 conversion. (Default.)
1 Enables V.42 LAPM to MNP 10 conversion.
2 Enables V.42 LAPM to MNP 10 conversion; inhibits MNP Extended Services
initiation during V.42 LAPM answer mode detection phase.
Result Codes
OK 0 or 2.
ERROR Otherwise.
3.2.6 Data Compression Commands
This section contains parameters to condition modem use of standard ITU-T V.42bis Data Compression Procedures.
3.2.6.1 +DS - Data Compression
This extended-format compound parameter controls the V.42bis data compression function if provided in the modem. It
accepts four numeric subparameters:
Syntax
+DS=[<direction>[,<compr_neg>[,<max_dict>[,<max_string>]]]]
Defined Values
<direction> Specifies the desired direction(s) of operation of the data compression function; from the DTE
point of view.
0 Negotiated; no compression (V.42bis P0=0).
3 both directions, accept any direction (V.42bis P0=11). (Default.)
<compr_neg> Specifies whether or not the modem should continue to operate if the desired result is not
obtained.
0 Do not disconnect if V.42bis is not negotiated by the remote modem as specified in
<direction>.
<max_dict> Specifies the maximum number of dictionary entries (2048 entries) which should be negotiated
(may be used by the DTE to limit the codeword size transmitted, based on its knowledge of the
nature of the data to be transmitted).
<max_string> Specifies the maximum string length (32 bytes) to be negotiated (V.42bis P2).
Reporting Current or Selected Values
Command: +DS?
Response:
+DS: <direction>,<compr_neg>,<max_dict>,<max_string>
Example: +DS: 3,0,2048,32 for the defaults and 2048 entry max dictionary.
