Nortel Networks NN43001-121 manual Network configuration

36Planning and engineering

Nortel recommends that you implement the Telephony Gateway and Services component to provide basic connectivity (which you can more readily debug), followed by the Remote Call Control (RCC) for more complex feature operation. Configure both Telephony Gateway and Services and RCC only in situations where both components are required.

Consider the following during the planning process.

•Consider the size of your network. See "Network Design" (page 36) for detailed information about determining your network architecture.

•Determine the type of users (internal and external users) and anticipated call traffic. For more information about type of users, see Table 5 "Maximum supported users for each topology" (page

52). For information about calculating the anticipated call traffic for the Communication Server 1000, see Communication Server 1000E Planning and Engineering (NN43041-220).

•Determine that the software and hardware components required for the CS 1000 are installed and have the latest software versions. For more information, see "CS 1000 and Signaling Server installation" (page 105).

•Determine that the software and hardware components required for Office Communications Server (OCS) 2007 have the latest software versions. For more information, see "OCS 2007 component installation" (page 105).

•Determine the system requirements for the OC 2007 client. For more information, see "OC 2007 client requirements" (page 47).

•Determine capacity requirements for all components. For more information, see "Capacity Planning" (page 46).

•Prepare your infrastructure.

•Plan for external user setup. For more information, see "Access Edge Server" (page 27).

•Plan your implementation strategy.

For more information on deploying OCS 2007, see the Microsoft Office Communications Server 2007 Planning Guide . Download Microsoft documentation from the Download Center at www.microsoft.com.

Network configuration

The main consideration when you plan and engineer the Converged Office desktop is the size of the network. Networks are divided into three main categories: small, medium, and large. Each type requires specific configuration.

The following sections describe typical network topologies to assist in determining capacity and robustness requirements.
