Whichever of the 2 spans is from the PSTN should be providing 
clocking...

i.e.
span=1,1,0,css,hdb3,crc4

Otherwise you may get clock slips on one or the other interface... also 
make sure the panasonic is getting clocking from the Asterisk server. 
That is clocking for the PRI's should go from the PSTN connect to the 
Asterisk server to the Panasonic otherwise you may well run into 
problems like this.
