<p class=MsoNormal style='margin-bottom:12.0pt'>the 40 ms latency requirement
only applies to communication between CCM nodes. Phones can be
further away from the CMs. Also, with newer versions of CM the latency
requirement can be as high as 80 ms between nodes depending on the amount of
available bandwidth you can dedicate to CM intercluster traffic and DB
replication.<br>
<br>
perhaps you can reevalute whether you need two clusters?<br>
<br>
have you read the SRND, good place to start for reading about CM design.<br>
