Systematic Investment Plan (SIP)

Do all the schemes provide me an option to invest via SIP?
What is the minimum amount needed to start an SIP?
Is there a minimum period for which I must make investments through SIP? What is the maximum number of months I can select for my SIP?
Are there any charges or penalties for terminating an SIP?
In any scenario, will my SIP be terminated automatically?
How can I STOP/ Terminate my SIP?
