Because the SBC 1k/2k ASM employs Microsoft's Windows Server operating system, it is necessary to periodically download Windows Updates. Updates are normally downloaded directly to the ASM from the Microsoft Windows Update website.
In some cases, the ASM may be installed in networks that do not have Internet access to Microsoft's Windows Update website, therefore the ASM requires an alternative method to download Windows Updates.
This document details how to configure a local Windows Server Update Services (WSUS) Server to permit the ASM to download any necessary updates via a local server.
The WSUS installation instructions are provided as a convenience. Please consult the Microsoft's WSUS documentation should you have any further questions or issues.
The WSUS server must have access to the Internet in order to download windows updates from Microsoft.
An additional benefit to using a WSUS Server is that the ASM installs Windows Updates much faster. The WSUS Server works by pre-fetching all necessary updates as they become available. When the ASM requests an update, the update itself is loaded to the ASM directly from the WSUS Server.
On the target WSUS Server, begin the WSUS installation by opening the Server Manager and selecting Add role and feature.
Click Add Features to accept the additional features required.
Select .NET Framework 3.5 Features.
Click Next until the Content tab, fill a folder the will host the update.
Click Next then Install, let the install complete and click on Launch Post-Installation tasks
Once the Configuration successfully completed, you can close the Wizard
Start the Windows Server Update Services, hit Next until the Proxy Server tab
Click Start Connecting to ensure the access to the Microsoft Server.
Choose your languages.
Click Begin initial synchronization then Finish
The WSUS Server must be configured to accept incoming requests from the ASM server. Use the instructions below to configure the WSUS server to accept incoming requests.
Go to Options, then Computer.
Choose Use Group Policy or registry settings one computers.
The ASM must be configured to use the local WSUS server instead of Microsoft's Windows Update site. There are two methods for configuring the ASM to use a WSUS Server to download updates:
To set the ASM down download from a WSUS Server:
Do not modify the Configure Automatic Update setting. See the warning below.
To set the ASM's WSUS Server via the ASM registry, modify the WindowsUpdate key with the Sonus Require values as noted below:
HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\WindowsUpdate
Do not modify the HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\WindowsUpdate\AU key to permit the ASM to automatically load updates from either the WSUS Server or Microsoft Windows Update site. Sonus selects specific updates to the ASM to ensure the SBC appliance operates within our published specifications, eliminating updates which might either break functionality or reduce the ASM's capacity.
Downloading unapproved updates to the ASM violates Sonus' Terms of Service
Go to ASM Roll-up Update page to apply ASM Roll-up updates on Sonus SBC 1000/2000 nodes.
Do not update ASM using any other method than what is documented.
