ADDRESS UPDATE INTERVAL
       Default: 10                         Value: 1-4294967296

       Minimum time, in seconds, allowed between updates of address information.
       More frequent modification to the set of local towers is prohibited.

   BACKTRANSLATION SEARCH PATH

       Describes the order in which name services will be searched for
       address-to-node-name translation requests when more than one name service
       is in use on a node and any associated naming templates for each
       directory service.

   INCOMING PROXY
       Default: True                              Value: Boolean

       Specifies whether to honor incoming proxy requests. If this attribute is
       set to false, requests to invoke proxies on incoming requests are
       ignored.

   INCOMING TIMER
       Default: 45                                Value: 0-65535

       Time, in seconds, to wait for a user module to issue an accept/reject
       call after a port enters a state indicating that a connection request
       was received. If the timer expires, Session Control aborts the transport
       connection with a timed out error. For OpenVMS, a zero 0 value
       directs Session Control to wait indefinitely without aborting the
       connection.

   MAINTAIN BACKWARD SOFT LINKS
       Default: False                             Value: Boolean

       Specifies whether Session Control should attempt to update the backward
       translation soft links when it detects an address change. If this
       attribute is set to false, Session Control will add no new backward
       translation soft links and it may delete any that it has created.

   MODIFY ACS CONTROL SET
       Default: True                               Value: Boolean

       Specifies whether Session Control should attempt to update the ACS
       access control set of the node object whenever it attempts to update
       the towers attribute for the node in the namespace.

   NAMING CACHE CHECKPOINT INTERVAL

       Amount of time, in hours, between times when the address and node-name
       information is checkpointed to disk from the in-memory, local naming
       cache.

   NAMING CACHE TIMEOUT

       Amount of time, in days, after which the address and node-name
       information for a node is deleted from the in-memory, local naming cache.

   NAMING SEARCH PATH

       Describes the order in which name services will be searched for
       node-name-to-address translation requests when more than one name
       service is in use on a node, and any associated naming templates for
       each name service.

   NON PRIVILEGED USER

       Specifies the Session Control on a non-privileged user account.

   SOFTLINK TIMER
       Default: 30 days                        Value: binary relative time

       Interval of time, in days, DECdns checks that an object pointed to by a
       backward translation soft link still exists.

   OUTGOING PROXY
       Default: True                           Value: Boolean

       Specifies whether to invoke a proxy on outgoing connection requests when
       the user does not explicitly specify to do so. If this attribute is set
       to false, no proxy is invoked.

   OUTGOING TIMER
       Default: 60                             Value: 0-65535

       Time, in seconds, to wait for an outgoing transport connection to be
       accepted before Session Control aborts the connection with a timed out
       error. For OpenVMS, a zero 0 value directs Session Control to wait
       indefinitely without aborting the connection.

   UPDATE RETRY INTERVAL
       Default: 60                             Value: 1-4294967296

       Time to wait before Session Control retries a failed attempt to update
       information in the namespace.  The default is 60 minutes.

   VERSION

       Session Control protocol version number. You cannot modify this
       characteristic.
