ztcfg -vvvv shows no error

this is the error it outputs in the asterisk console
[Oct 27 14:30:35] WARNING[4139]: mtp.c:457 t2_timeout: MTP2 timer T2 timeout (failed to receive 'O', 'N', or 'E' after sending 'O'),     initial alignment failed on link 'l1'.

A similar problem was posted on 15th January, 2008 by Pawel Ratajewski (Forweb) rataj at 4web.pl
but i could not see any posted solution in the archives.

Please help!
