[hcflinux] Is a Voice Modem without AT+FCLASS=8 capability possible ?

[Nicolas Duclos-Hindie]

Hello hcflinux post list people,

After having searched through 
inet posts, some Modem, vgetty HOWTOS, 
and readmes, a question remains UNANSWERED.

The local dealer tells me one thing,
(your modem does voice with softwares, on windows)
but the modem tells me another, on linux ?!?

(main) QUESTION:
??????????????????????????????????????
Does anyone know if the PCI HCF modem
   AOpen FM56-PLM  (CONEXANT chip set)
"should" be able to AT+FCLASS=8 ?
??????????????????????????????????????

??????????????????????????????????????
OR, is voice capability (vgetty) possible
without the AT+FCLASS=8 ???
?????????????????????????????????????

Once the modem is installed on 
a Linux station, using "lspci" 
we get to read this line:
======================================
00:0d.0 Communication controller: Conexant HCF 56k
Data/Fax/Voice Modem (rev 08)
======================================
Where we can read the "Voice Modem" string.


Using the "listmodem.sh" obtined from:
http://www.linuxant.com/drivers/modemident.html
we see:
======================================
  PCI CONFIGURATION INFORMATION READ:
     Vendor Id         : 14F1
     Device Id         : 1034
     Revision Id       : 1
     Sub Vendor Id     : 14F1
     Sub Device Id     : 1034

  DEDUCED INFORMATION:
     Vendor Name       : CONEXANT
     Device Name       : HCF P85 Data/Fax/Remote TAM
     Modem Type        : HCF
     Download Site     :
http://www.mbsi.ca/cnxtlindrv/
======================================
Notice the "Remote TAM" instead
of the "Voice Modem" previously obtained...


After having installed the:
hcfpcimodem-0.99lnxtbeta03042700-1.i386.rpm
(from the "http://www.linuxant.com" download site)
on a RedHat 9.0 Linux station
(that seems to have recompiled nicely),

using "minicom" we can get the modem 
to dial out OK (ATDTXXX-YYY),
but the AT+FCLASS=? command gives:
======================================
AT+FCLASS=?                                          
0,1,1.0                                              

OK

AT+FCLASS=8
ERROR
======================================
Notice that "AT+FCLASS=8" (voice)
seems to be unavailable" !
It is not even listed out of AT+FCLASS=?

????????????????????????????
Is the "voice" really unavailable ???
If so, is it because of the modem, 
or the driver ?
????????????????????????????

Returning to the AOpen FM56-PLM 
product web site
http://www.aopen.com/products/modem/fm56plm.htm
We can still see that 
this PCI modem should have:
========================================
Telephone Answering Machine (TAM) and 
Voice Mail Operations
========================================

?????????????????????????
Should the AT+FCLASS=8 be available
according to the TAM + Voice Mail note ?
?????????????????????????


On the "aopenplm" user manual,
(obtained from the web)
http://www.aopen.co.jp/tech/manual/modem/modem_pci/aopenplm.pdf

There is a chapter for "voice commands" 
that start with:
==================================================
5. List Of Voice Commands (Voice Models Only)
...
==================================================

??????????????????????????????????????
(Voice Models Only) ? How do we know
if we got a "voice model" or NOT ???
??????????????????????????????????????

In the "hcflinux" posts, we found that:
http://www.mbsi.ca/pipermail/hcflinux/2002q3/000428.html
in some cases, the "Voice in hcfpcimodem" may
not be available:
=========================================
Marc Boucher, marc at mbsi.ca 
wrote on that other post:
...
Unfortunately you have an older '71' datapump and the
voice 
functionality has only been tested with the newer '73'
datapump.
This limitation will be documented in the next
version. Also the
modem will no longer report the availability of FCLASS
8 unless
the right datapump is present.
...
=========================================


On our modem, the command "ATI6" 
with minicom gives:
========================
ATI6                                                 
DP Part 74                                           
DP Rev  BA
V90     SPX RAM Ver 16
V90     CTL RAM Ver 16
========================

????????????????????????????????????
We observe that the "DP Part 74" is not "73".
Is it possible that the DATADUMP 74
makes the Voice feature unavailable
with the "hcfpcimodem" current driver ?
?????????????????????????????????????

Can we ever hope to use the "voice" features 
of this modem (TAM, voice mail...)
with a Linux workstation ?

Thanks,


Nicolas
