How to model a bussystem with EA

[Hans-Christian]

In the sequence diagrams I want to use logical signal names representing a bussystem like an ethernet or a CAN-bus. But in reality I have different deployments with different busses but with the same sequences. So my problem is to model this association between one logical signal to more than one physical signals depending on the physical deployment and to export this right in rtf.
One idea I had was to use the alias field and to put the signals as methods in classes and to link the classes with associations. But this is only an intellectuel link between the signals.

Does anyone has a good idea ?

thanx

An other idea to solve this problem I have is to put the methods as operations in classes (like my first proposal) and to create a link (association, dependency or something like this) between the classes with the operation names as role description. For this the link between the logical signal and the corresponding physical signal would be modeled in UML. But this is also more an intellectual link.
So for this the problem is to export it in a good way with the RTf Exporter (New RTF Style Template Editor). The Classes and methods have to be in the package where which is exported directly. But this is no variant for me.
If you add the classes in a diagram and select "Document each contained element in RTF" you don´t have the possibility to export the Source and the target of the connector (which is the association between the classes) like in connectors of a package.

Somebody any ideas to achieve this?

Thanx for all ideas
