It indeed is a typo. I just made further research and it should be something
like this I check the clock source options on the CVOICE book Third Edition
thanks you very much
for Internal Clock:
1. controller T1 1/0
framing crc4
linecoding hdb3
clock source internal
ds0-group timeslots 1-15 type e&m-wink-start
for External Clock
2. controller T1 1/0
framing esf
linecoding ami
clock source line
ds0-group timeslots 1-12 type e&m-wink-start
