OC 2007 client requirements

The PC that runs the OC 2007 must be registered to the domain in which the OCS 2007 server runs. The OC 2007 client can be installed on a PC that runs most versions of Microsoft Windows with the hardware device driver API DirectX 9 or later. For more information on the OC client requirements, see Table 11 "Office Communicator client requirements" (page 54).

For more information about deploying the OC client, see Microsoft Office Communicator 2007 Deployment Guide . Download Microsoft technical documentation from the Download Center at www.microsoft.com.

Load Balancer capacity requirements

Capacity planning for OCS 2007 is measured in terms of the number of clients. However, this becomes difficult to measure because of the enhanced capabilities and services for a pool and the variety of components that can be enabled in OCS 2007. Components can reside on separate servers, which adds to the complexity of capacity planning. A single client user can have multiple connection instances that depend on the features enabled. Each feature has different bandwidth requirements that can differ from one enterprise to another.

For more information on capacity guidelines, see Table 5 "Maximum supported users for each topology" (page 52).

For more information about capacity planning, see the Microsoft Office Communications Server 2007 Planning Guide. Download Microsoft technical documentation from the Download Center at www.microsoft.com.

SIP CTI (TR/87) services requirements

When you plan for capacity with Session Initiation Protocol Computer Telephony Integration (SIP CTI) services, observe the following restriction: For a single CS 1000 that supports multiple nodes, (each with SIP CTI services enabled), you can establish multiple SIP CTI (TR/87) sessions for a DN through the same node—but not through different nodes.
