CMS offline Installation & Internet

I just would like to ask When we run Symantec installtion Manager (SIM) and select Altrirs Client Mangement Suite (CMS) from there then it download its files from Internet. This means we need to have Internet on that machine.

Is it Possibel can we do offline Instlaltion without inerenet as due to some organizational policy internet is not available on the server.

Regards.
Saqib.
