Overview on ATM Circuit Manager

CA Spectrum's ATM Circuit Manager lets you model both the physical and logical connectivity of your ATM infrastructure. You can represent an ATM infrastructure that you own and manage, or one that is partially or fully owned and managed by a service provider. The following illustration shows a sample modeled ATM network that includes partial management by a service provider.

In a fully or partially meshed ATM network, each physical ATM interface may have logical connections with many other ATM devices. However, without ATM Circuit Manager, CA Spectrum's modeling functionality will only model physical ATM interfaces, leaving logical ATM interfaces unmanaged and limiting connectivity to physical links. Therefore, without ATM Circuit Manager, it is impossible to accurately represent the logical connectivity of the switches and routers in the ATM network.
The physical connectivity of an ATM network is represented by

associations between the ATM physical interface models and the connected device models. This lets you represent true data relay paths between the clients and helps ensure proper fault isolation. You can represent the physical connectivity of the ATM network by connecting a physical ATM interface model to another physical interface model, to a device model, or to an ATM_Cloud model.
The logical connectivity of an ATM network is represented by logical connections between virtual link models. These virtual link models represent the endpoints of a virtual connection. Virtual link models include VPLs (virtual path links, also referred to as virtual path trunks or VPTs) and VCLs (virtual channel links). Virtual link models are associated with a lower-layer interface model using the HASPART relation. The lower-layer interface may be a physical ATM interface model, or, in the case of a VCL, it may be a VPL or VPT model.
The following illustration shows the relationships between the modeled physical and virtual components in an ATM network.
SPEC--ATM Circuit Manager
An actual ATM network would contain (collect) multiple switches. For simplicity, the illustration shows just one switch.
Once you have modeled your ATM network, you can use ATM Circuit Manager to isolate faults within the network, evaluate performance, and monitor quality of service.
