Nortel Networks NN43001-121 manual Multiple customer network, Large network configuration

40Planning 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.

Large network configuration

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).
