Does anyone know where one could find any examples of a Service Level Agreement for the AAL5?
You need to ask their account manager for that. They are the only one who can provide you with those info because some of them may be confidential between the service provider and the subscriber (or prospective subscriber). Anyone here who give you those info will not be honoured by the said service provider as some SLAs if not all of them has a legal bind.
Asking such information from the service provider does not automatically bind you with any contract with them (beside NDA).
