Hi,
I've seen some reports about ruuning Intel modem with 537 or MD3200
chipset running with Zaptel drivers as a FXO port. Did anybody managed
to set up a PCI faxmodem based on Intel536ep chipset to work with * and
Zaptel drivers?
Modem seemd to work just fine with Linux, but the driver says no;)
some more info:
Linux 2.4.26
mazuchna:~# cat /proc/pci | grep 536
Communication controller: Intel Corp. 536EP Data Fax Modem (rev 0).
mazuchna:~# lsmod
Module Size Used by Tainted: P
ztdynamic 6692 0 (unused)
zaptel 177280 0 [ztdynamic]
Intel536 876524 0 (unused)
mazuchna:/lib/modules/2.4.26/misc# insmod wcfxo
Using /lib/modules/2.4.26/misc/wcfxo.o
/lib/modules/2.4.26/misc/wcfxo.o: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters,
including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg
is there anything more I can do?

buy a x100p for 100 bucks and support digium. Matteo. P.S. and you'll have free installation support from digium and a rock solid hw made for asterisk.

I for one would love this. I do not have any test equipment to determine the level I am sending at, but if I could at least figure out what levels to have my rxgain values set to, that would help. I remember seeing somewhere that you can use a program (part of the zt suite if I remember correctly) to view the audio levels on the FXO card like an on-screen vu meter. I can use that and dial up my telco milliwatt test number and adjust accordingly. I asked where that tool was on the IRC channel, but they seemed to not know either. I have searched as I know I saw it, but can't find it again. Please post a guide like this to the Wiki or some other location, and be assured it will help at least one person out, probably many more. -----Original Message----- From: Rich Adamson [mailto:radamson@routers.com] Sent: Monday, April 19, 2004 6:43 AM To: asterisk-users@lists.digium.com Subject: Re: [Asterisk-Users] Intel 536ep as a FXO?> As someone who used to adjust hybrids for a living a number of years > ago, I can tell you, complex impedence matching is only a part of the > equation.Same here.> The most important part is proper gain structure.

The "picture" below may > help to clarify:A major part of the problem implementing * into a pstn environment is that few implementors actually understand transmission basics, a smaller percentage actually have the test gear to measure the values, and even a smaller number understand what impedence, DBm, noise levels, twisted pair, induction, etc, mean in terms of pstn interface performance. Combine that with dropping an FXO interface into a pstn environment where the transmission levels to the CO are basically unknown, SOHO impedence mismatches abound, bridged analog phone sets are commonplace, and assumptions that plug-n-play applies across the board including the x100p, its fairly obvious why so many people bad-mouth the "hardware". Its also interesting that in about eight months on this list no one has asked what the milliwatt generator is for, how to find the telephone number of the pstn generator, how to measure the levels or what the objectives should be, etc. The transmission levels that were noted in the original posting are those associated with the analog toll network, but the principle still applies. Maybe a couple of us should write a whitepaper for beginners on the topic.

This may not be the case in all areas, but in my area with Qwest as well, all exchanges have the test at xxx-9996. For example, my number is in the 208 area code, 459 exchange, so the full number would be 208-459-9996. It is not tied to any specific number, so I can use any exchange local to me such as 323-9996. It may or may not work in your area, so try not to do it at 3:00 AM until you have verified the number.

The next question for me is: How do I found out my telco milliwatt test number? I'm in Washington State using Qwest. The way I understand this, I'm to dialup the telco milliwatt test number and adjust the rxgain values using ztmonitor tool until the "Max Audio Hit" is in the middle of the bar graph for a normal conversation?

I have > searched as I know I saw it, but can't find it again.The tool you're looking for is /usr/src/zaptel/ztmonitor [root@phoenix zaptel]# ./ztmonitor Usage: ztmonitor <channel num> [-v] [-f FILE] [root@phoenix zaptel]# ./ztmonitor 1 -v Visual Audio Levels. -------------------- Use zapata.conf file to adjust the gains if needed. ( # = Audio Level * = Max Audio Hit ) <----------------(RX)----------------> <----------------(TX)----------------> ##################* Keep in mind that tool is nothing more then an audio VU meter and was not intended to be an accurate means of measuring transmission levels. I think bkw (probably with Mark) wrote it back in the November/December timeframe as a simple tool for adjusting rxgain, etc. About that same time, the echo cancelling mechanism (for the x100p) was rewritten to "sense" the audio reflection (or echo) during the first half-second or so of an initial pstn call. (That was a substantial improvement over previous cancellation methods without a doubt. If I recall recorrectly, that mechanism was reduced to sending an outbound short duration pulse or burst, and measuring the reflected energy. Sort of a snapshot at the start of an analog call. It's okay, but certainly not the equivalent of commercial analog cancellation products including mux's.) I've not had to revisit the x100p gain adjustment effort for several months, but seems to me that it was necessary to completely stop and start * each time an adjustment was made to the rxgain/txgain settings in zapata.conf (a simple reload wasn't adequate).

hi I want to setup my intel 537 modem to "place" and "receive" pstn call. So far Asterisk registers my modem. What do i do next. I couldnt find any help setting up my modem. p.s: can any one tell me the full extent of modem functionality in asterisk ( AND please dont mention digium cards... i am talking about cheap analogue voice modems here) --- Marcin Mazurek <M.Mazurek@netsync.pl> wrote:> Hi, > > I've seen some reports about ruuning Intel modem > with 537 or MD3200 > chipset running with Zaptel drivers as a FXO port. > Did anybody managed > to set up a PCI faxmodem based on Intel536ep chipset > to work with * and > Zaptel drivers? > Modem seemd to work just fine with Linux, but the > driver says no;) > > some more info: > > Linux 2.4.26 > > mazuchna:~# cat /proc/pci | grep 536 > Communication controller: Intel Corp. 536EP Data > Fax Modem (rev 0). > > mazuchna:~# lsmod > Module Size Used by Tainted: P > ztdynamic 6692 0 (unused) > zaptel 177280 0 [ztdynamic] > Intel536 876524 0 (unused) > > mazuchna:/lib/modules/2.4.26/misc# insmod wcfxo > Using /lib/modules/2.4.26/misc/wcfxo.o > /lib/modules/2.4.26/misc/wcfxo.o: init_module: No > such device > Hint: insmod errors can be caused by incorrect > module parameters, > including invalid IO or IRQ parameters. > You may find more information in syslog or the > output from dmesg > > is there anything more I can do? > tia > mazek > > -- > http://mazek.netsync.pl/ ::: nic-hdl: > MM3380-RIPE > GnuPG 6687 E661 98B0 AEE6 DA8B 7F48 AEE4 776F 5688 > DC89 > _______________________________________________ > Asterisk-Users mailing list > Asterisk-Users@lists.digium.com >http://lists.digium.com/mailman/listinfo/asterisk-users> To UNSUBSCRIBE or update options visit: > >http://lists.digium.com/mailman/listinfo/asterisk-userssers> To UNSUBSCRIBE or update options visit: >http://lists.digium.com/mailman/listinfo/asterisk-users __________________________________ Do you Yahoo!?
