Copy Quality Checking

Class 2.1

+FCQ

 

Write syntax: +FCQ=<rq>,<tq>

Values:

0, 1 for <rq>

 

0 for <tq>

 

Default:

1 for <rq>

 

 

0 for <tq>

 

 

Other values for <rq> and <tq> are not supported in the Multi-Tech implementation.

 

The +FCQ parameter controls copy quality checking and correction by a facsimile

 

modem. The <rq> subparameter controls copy quality checking and correction of

 

data received from the remote station and delivered to the local host; the <tq>

 

subparameter controls copy quality checking and correction of image data received

 

from the local host and sent to the remote station.

 

The modem reports on Received Copy Quality to the host in the page status report,

 

+FPS:<ppr>,<lc>,<blc>,<cblc>,<lbc>, and records it in the +FPS parameter.

 

+FCQ=0,0

modem receive copy quality checking is disabled; the modem will

 

 

generate copy quality OK (MCF) responses to complete pages, and set

 

 

+FPS=1. modem transmit copy quality checking is disabled; the host is

 

 

responsible for T.4 or T.6 compliance.

 

+FCQ=1,0

modem receive copy quality checking is enabled; the modem will

 

 

determine the recommended Post Page Message, and store it into the

 

 

+FPS parameter. modem transmit copy quality checking is disabled; the

 

 

host is responsible for T.4 or T.6 compliance.

Class 2

+FCQ

 

Write syntax:

+FCQ=<value> Valid values: 0, 1

Default value:

0

 

 

This parameter controls copy quality checking by the receiving facsimile modem.

 

The modem will generate a page transfer report, indicated with the

 

+FPTS=<ppr>,<lc>,<blc>,<cblc> response and posted in the +FPTS parameter. The

 

+FCQ parameter setting also conditions the generation of bad line count <blc> and

 

consecutive bad line count <cblc> subparameters.

 

+FCQ=0

The modem does no copy quality checking. The modem will generate

 

 

copy quality OK (MCF) responses to complete pages, and set +FPS=1.

 

+FCQ=1

The modem can check 1-D Phase C data. The host must check copy

 

 

quality for 2-D Phase C data. On new -V92 modems, +FCQ=1 means it

 

 

will also check 2-D Phase C data.
