WSUS Server updating other Servers

We have a Microsoft Server 2012 that we would like to use as the central/controlling server for updating other servers (Windows 2012, SBS 2011) and workstations (Windows 7). For security reasons the networks only interconnect at particular times of the week.

Is it possible to get a central WSUS server to pull, or be pushed for, all the updates for a variety of servers and workstations?

I'm not sure I quite understand your question.  The way WSUS works is that you configure the WSUS server to poll the Microsoft update servers for updates for whatever Microsoft products you specify.  So, you can specify any of a large number of operating systems, server software (like Exchange or SQL) and workstation software (like Office) on your WSUS server. The WSUS server then pulls down from the Microsoft update servers a list of the updates available for those OS's and software packages.  

The WSUS server also receives information from each client workstation (assuming you've configured all this through group policies) as to what OS and software are on that workstation and what updates are needed. This is a "push" activity from the workstation end once the workstation is configured to connect to the local WSUS server through group policies. Then, again depending on your configuration, you approve updates for installation and the updates you've approved are downloaded to the WSUS server. The next time each client (server or workstation) contacts the WSUS server it will pull down those updates that are needed by it.

The day and time that the WSUS server is polled by the client machines can be specified through the group policy settings that are configured for your domain.

That's how I understood WSUS to work. It's basically a three tier model:

Microsoft > WSUS Server > Workstation

Is it possible to add in a forth tier like:

Microsoft > WSUS Master Server > WSUS Servers > Workstation

yes you can configure a downstream replica so that one server pulls the updates and other servers in other locations pull from that first server

Yes, it is possible to configure an upstream server (or master server) for another WSUS server.
