40 Planning and engineering
The redundant, primary, and alternate NRS can be either the VxWorks NRS
or the Linux-based NRS (SPS/SRS). For the OCS 2007 Enterprise Edition
server, a SQL back end database server is a requirement.
ATTENTION
If you set up more than one server that runs the Enterprise Edition of Microsoft
Office Communications Server 2007, you must use a Load Balancer in
accordance with the Unified Communications Engineering Rules and Guidelines.
The Load Balancer ensures that the Fully Qualified Domain Name (FQDN) of the
pool is not equal to the FQDN of any Front End server in the pool.

Multiple customer network
You can configure the CS 1000 with a number of customers that have
their own set of telephones, trunks, features, restrictions, and numbering
plans. In the Converged Office environment, each customer is treated as a
separate machine. Each customer shares one OCS deployment, but has
their own Node Number, MCM, Signalling Server, and SIP domain in the
forest. For more information about the Multiple Customer environment, see
Features and Services (NN43001-106).
