-## ExpressRoute Direct circuits
-
-Azure ExpressRoute allows you to extend your on-premises network into the Microsoft cloud over a private connection made possible through a connectivity provider. With ExpressRoute, you can establish connections to Microsoft cloud services, such as Microsoft Azure, and Microsoft 365.
-
-Each peering location has access to the Microsoft global network and can access any region in a geopolitical zone by default. You can access any global regions when you set up a premium circuit.  
+> [!NOTE]
+> 400-Gbps is available in limited ExpressRoute peering locations and requires enrollment. Complete the [enrollment form](https://aka.ms/AA101nu0) to get started
 
-The functionality in most scenarios is equivalent to circuits that use an ExpressRoute service provider to operate. To support further granularity and new capabilities offered using ExpressRoute Direct, there are certain key capabilities that exist only with ExpressRoute Direct circuits.
+## ExpressRoute Direct circuits
 
-You can enable or disable rate limiting for ExpressRoute Direct circuits at the circuit level. For more information, see [Rate limiting for ExpressRoute Direct circuits](rate-limit.md).
+ExpressRoute circuit is a logical connection between your on-premises infrastructure and Microsoft cloud services provisioned on an ExpressRoute Direct port pair. Each circuit has fixed bandwidth mapped to an ExpressRoute Direct in a location. 
 
 ## Circuit SKUs
 
-ExpressRoute Direct supports large data ingestion scenarios into services such as Azure storage. ExpressRoute circuits  with 100-Gbps ExpressRoute Direct also support **40 Gbps** and **100 Gbps** circuit bandwidth. The physical port pairs are **100 Gbps or 10 Gbps** only and can have multiple virtual circuits. 
+ExpressRoute Direct supports Local, Standard and Premium SKU's. For pricing details, see [ExpressRoute pricing](https://azure.microsoft.com/pricing/details/expressroute/).

-> [!NOTE]
-> You can create logical ExpressRoute circuits on top of your selected ExpressRoute Direct resource of 10-Gbps or 100-Gbps up to the subscribed Bandwidth of 20 Gbps or 200 Gbps. For example, you can create two 10-Gbps ExpressRoute circuits within a single 10-Gbps ExpressRoute Direct resource (port pair).
+## Rate-limiting on the Circuit
+You can enable or disable rate limiting for ExpressRoute Direct circuits at the circuit level. For more information, see [Rate limiting for ExpressRoute Direct circuits](rate-limit.md).
