<DIV><FONT face=Arial size=4>As you know, when overlap signaling is used, when
enough digits have been collected to identify the next exchange, an IAM is sent
to the next exchange along the route to the called party, the remaining digits
are sent in subsequent SAM messages.</FONT></DIV>
<DIV><FONT face=Arial size=4></FONT> </DIV>
<DIV><FONT face=Arial size=4>My question is: how does the local exchange of the
called party decide whether all digits of the called party number has been
collected or not (i.e., how does the local exchange of the called party know
whether or not the SAM it received is the last one), especially when the called
party number is of variable length?</FONT></DIV>

<DIV><FONT face=Arial size=4>I looked through some of the ITU-T Q.76X series but
failed to find the answer, I hope any of you will kindly help me answer my
question or refer me to some information sources, thanks in
advance!</FONT></DIV></BODY></HTML>
