<DIV></DIV>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><BR><A

but the bandwidth requirements are too high - over the specified 40ms (one
way) - hence the need for differing clusters. The set up you have
suggested is what we have already.</FONT></SPAN></DIV>
