A Seasonal Service
If you are seasonally using optical internet or/and IPTV (in country home, village, etc.) and therefore use the service for the certain period of the year, within the seasonal service you are able to suspend the service for some period without affecting the standard conditions of a service or an agreement. For renewing of the service it is necessary to reactivate your account without any other installations and adding devices, only for the fee of reactivation.
See here additional detailed information about seasonal service.
