For example, class C and class D boundary clocks have been added to G.8273.2, along with an enhanced EEC specification (G.8262.1). Similarly, there is a new enhanced PRTC specification (G.8272.1), and Class B PRTC specification (G.8272) has also been defined. The network limits associated with these enhanced clock specifications are still under development.
