Aculab channel driver

Hello,
We tried to configure Aculab Prosody PCI card rev1.5 with Asterisk.
When we run asterisk we get the following error:

[Aug 28 11:08:39] ERROR[9185] chan_aculab.c: No valid timeslot for channel 1
[Aug 28 11:08:39] WARNING[9185] chan_aculab.c: Aculab config: Unable to register channel ‘171547:0:1-30’

any help?
