The Accounting Rollover Interval characteristic attribute controls
 how often the DSA closes the current accounting file and creates a
 new one, that is, rolls over the accounting file. The interval uses
 the accounting rollover start time as its starting point. For
 example, if you set the accounting rollover interval to 6 hours, the
 first accounting file rollover will take place at the time specified
 by the Accounting Rollover Start Time attribute, and the second
 rollover six hours later.

 Syntax:

 	SET DSA ACCOUNTING ROLLOVER INTERVAL <time>
 	SHOW DSA ACCOUNTING ROLLOVER INTERVAL

 where <time> is the required interval specified in binary relative
 time.  For example, to make the DSA  rollover the accounting file
 every twelve and a half hours, enter the following:

 	> SET DSA ACCOUNTING ROLLOVER INTERVAL 12:30:00

 When the DSA rolls over the accounting file, it generates the
 Accounting File Rollover event. You can then process the closed
 accounting files using your decoding and billing utility.

 On Tru64 UNIX systems, accounting files are stored in
 the /var/dxd/accounting directory. On OpenVMS systems, accounting
 files are stored in the directory pointed to by the DXD$ACCOUNTING
 logical.

 Note that accounting files are neither purged nor deleted
 automatically by the DSA.

 The default setting for this characteristic attribute is 12 hours.

 This attribute has no effect if the Accounting Facility
 characteristic attribute is set to OFF.
