Desperate Help needed with TDM11B

Hello:

After configuring FXS and FXO channels of a TDM11B card, I can make calls from the telephone attached to the TDM11B card to the outsite (the PSTN, analog line), The problem is when I try to dial from the PSTN to my asterisk box (it has to make ring the handset on the TDM card), but I got infinite:

“Poopy (00) on card 4!”

What is the problem?. I’m running latest Asterisk and Zaptel software on a lineox 4 linux.

This is the output of the wctdm module loaded with debug=1

ACPI: PCI interrupt 0000:00:08.0[A] -> GSI 19 (level, low) -> IRQ 169

and when receiving a call from the PSTN I see this on /var/log/messages

What should be the problem?. What am I doing wrong?.

my ztcfg -vvv says

Zaptel Configuration

Channel map:

Channel 01: FXO Kewlstart (Default) (Slaves: 01)
Channel 04: FXS Kewlstart (Default) (Slaves: 04)

2 channels configured.

Thanks a lot in advance for the help.
