[Asterisk-Users] Re: Problem with TDM400P

Greetings all,

    I'm new to asterisk... Finally got two IP phones and two TDM400P's (one 
with four FXO modules and one with four FXS modules)... Began experimenting 
a couple days ago and have ran into a very aggrevating problem.

    My system consists of the following hardware:

	Abit BL7-RAID motherboard
	Pentium 4 1.6GHz processor
	512MB SDRAM
	2 TDM400P cards
	2 3Com 3c905 ethernet cards

    And the following software:

	Redhat Linux 9.0 updated using FedoraLegacy.org's repository and yum
	Kernel 2.4.27
	Asterisk from the latest CVS image as of two days ago

    The problem I am running into is very random and very irritating. I'm 
about ready to pull my hair out... Basically, one of my TDM400P cards 
refuses to initialize about 1/3 to 1/2 of the time after reboots... When I 
modprobe wcfxs I get the following:

# modprobe wcfxs
Freshmaker version: 71
Fresmaker passed register test
Module 0: Installed -- AUTO FXS/DPO
Module 1: Installed -- AUTO FXS/DPO
Module 2: Installed -- AUTO FXS/DPO
Module 3: Installed -- AUTO FXS/DPO
Found a Wildcard TDM: Wildcard TDM400P REV E/F (4 modules)
ZT_CHANCONFIG failed on channel 5: No such device or address (6)
/lib/modules/2.4.27/misc/wcfxs.o: post-install wcfxs failed
/lib/modules/2.4.27/misc wcfxs.o: insmod wcfxs failed

    I just ran into a new problem a minute ago when I tested it again:

# modprobe wcfxs
Freshmaker version: 71
Freshmaker passed register test
Module 0: Installed -- AUTO FXO (FCC mode)
Module 1: Installed -- AUTO FXO (FCC mode)

Did you forget that FXS interfaces are configured with FXO signalling
and that FXO interfaces use FXS signalling?
/lib/modules/2.4.27/misc/wcfxs.o: post-install wcfxs failed
/lib/modules/2.4.27/misc wcfxs.o: insmod wcfxs failed

    However, about 50% of the time I get a good modprobe of both cards 
which looks like:

# modprobe wcfxs
Freshmaker version: 71
Freshmaker passed register test
Module 0: Installed -- AUTO FXO (FCC mode)
Module 1: Installed -- AUTO FXO (FCC mode)
Module 2: Installed -- AUTO FXO (FCC mode)
Module 3: Installed -- AUTO FXO (FCC mode)

Module 2: Installed -- AUTO FXS/DPO
Module 3: Installed -- AUTO FXS/DPO

    I have moved the cards to different PCI slots... I have stripped out 
the ethernet cards... I have disabled different combinations of on-board 
peripherals (in hopes of freeing up spare IRQ's)

    In the end, I have just become more frustrated with these Digium cards 
than I was previously.

    What am I doing wrong?? Any advice would be appreciated.

    I'd love to get started with all this stuff I spent my hard-earned 
money on, but so far it's just a pile of impressive looking electronics 
that doesnt do anything other than make me pull out hair.

Thanks,
Brad

P.S. -If any of you are wondering why I have two ethernet cards installed 
-- I want the phones on a private LAN since my normal LAN gets hit pretty 
hard at times and I dont want call quality to decline because of this. But 
the problems described above also occur when no network cards are installed 
whatsoever...
