Small network configuration
Medium network
A medium network can include the following components:
• one or multiple CS 1000 systems with Media Gateway and Signaling
Server
• a Primary NRS with an Alternate Network Routing Service (NRS) that
co-reside on one of the Signaling Servers
• up to 5000 users
• high availability with system redundancy for OCS 2007
You will need:
• an Office Communications Server 2007 Enterprise Edition
• an OCS Proxy server that runs MCM 3.0
• a Mediation Server
If you install only one OCS 2007 Enterprise Edition server, a Load Balancer
is not required. SPS (Linux-based NRS) does not support co-residency.
