Configure Time Periods
----------------------

A time period specifies a time range that includes a start time and end
time. Time periods also specify a repetition interval either as days of
the week or a specified date on the yearly calendar. You define time
periods and then associate the time periods with time schedules. A
particular time period can be associated with multiple time schedules.

.. note::

   VOSS-4-UC provides one **All the time** time period. The **All the time**
   period is a special, default time period that includes all days and hours,
   and cannot be deleted.

1. Sign in as provider, reseller, or customer administrator.
2. Make sure that the hierarchy path is set to the node where you want to
   configure the new time period.
3. Perform one of these options as appropriate:

   * If you logged in as provider or reseller administrator, choose
     **Apps Management > CUCM > Time Periods**.
   * If you logged in as customer administrator, choose
     **Apps Management > Advanced > Time Periods**.

4. Perform one of these options as appropriate:

   * To add a new time period, click **Add**, then go to Step 5.
   * To edit an existing time period, choose the time period to be updated by
     clicking it in the list of time periods, then go to Step 6.

5. If the **Network Device List** popup window appears, choose the NDL for the time
   period from the drop-down menu. The window appears when you are on a nonsite
   hierarchy node. If you are at a site hierarchy node, the NDL associated with
   the site is automatically used.

   Note:

   The **Network Device List** drop-down menu only appears when a time period is added;
   it does not appear when you edit a time period.

6. Enter a unique name for the new time period in the **Name** field, or modify the
   existing Name if desired. This field is mandatory. Enter a name in the **Time
   Period Name** field. The name can comprise up to 50 alphanumeric characters. It
   can contain any combination of spaces, periods (.), hyphens (-), and underscore
   characters (_).

   Use concise and descriptive names for your time periods. The hours_or_days
   format usually provides a sufficient level of detail and is short enough to
   enable you to quickly and easily identify a time period. For example,
   office_M_to_F identifies a time period for the business hours of an office
   from Monday to Friday.

7. Complete the other fields as appropriate.
