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.
