T.30 Phase C Page Reception Responses  
Receive Page Transfer Status  
Class 2.1 
+FPS: 
Syntax:  
 
+FPS:<ppr>,<lc>,<blc>,<cblc>,<lbc
The +FPS:<ppr> response is generated by the modem at the end of Phase C data 
reception in execution of a +FDR command. 
The <ppr> response is generated by the modem; it depends on the modem for T.4 or 
T.6 error checking capabilities, controlled by the +FCQ parameter. See Table 3.0 for 
<ppr> values. 
The receiving modem may count lines and bad lines and report them. Values are: 
 
<lc> line 
count 
 
<blc> bad 
line 
count 
 
<cblc>  consecutive bad line count 
 
<lbc>  lost byte count due to modem buffer overflow 
The line counts are qualified by the modem’s copy checking capabilities, controlled 
by the +FCQ parameter. If the modem is not configured to count lines, or if line 
counts are irrelevant (e.g. in Binary File Transfer mode, Recommendation T.434) the 
modem sets the line counts to 0.  
A receiving host may inspect <ppr> and write a modified value into the +FPS 
parameter. The modem will hold the corresponding post page response message 
until released by a +FDR command from the host.

Class 2 
+FPTS: 
Syntax:  
 
+FPTS:<ppr>,<lc>[,<blc>,<cblc>][,<lbc>] 
The Class 2 response is similar to the Class 2.1 response, except that it may also 
use <ppr> codes 0, 6, and 7, which are not used in the Class 2.1 response.
