With the DLS (Deployment Service) Device Management Integration feature, Lotus Sametime Unified Telephony Assistant was enhanced to coordinate Lotus Sametime Unified Telephony subscriber management and DLS-based device management. With this feature DLS plug&play is now fully supported by the Assistant.
For configuration changes that are performed from the Assistant
, settings are consistently applied in either direction:
when a subscriber is created, a virtual device is seamlessly created in DLSNote:
when a subscriber is updated, the corresponding DLS devices (virtual and registered) are updated accordingly
when a subscriber's device configuration is updated, the subscriber's configuration is updated accordingly
when a subscriber is deleted, the administrator decides whether deletion of related devices and line keys in DLS shall take place
In order to use DLS Device Management Integration it is necessary to assign a DLS to the related Business Groups.
The goal of DLS Plug&Play is to automatically provide the supported workpoints with the parameters required for registering at a gatekeeper or SIP server. It is implemented using virtual devices, i.e. a set of device attributes that are inherited by a real device upon registration to DLS. In particular, when a device registers to DLS, a lookup is made in the DLS DB for a virtual device matching the Terminal Number (E.164) or the Device ID (MAC address) of the registering device. If a match is found, the real device downloads the configuration of the virtual device.
Lotus Sametime Unified Voice Assistant is able to create virtual devices in two ways:
At the time a subscriber is created
By explicit creation at the integrated Device Management GUI
Simplified DLS Server Assignment
Since Lotus Sametime Unified Telephony.1 the association between subscribers and DLS is carried out at the BG (Business Group) instead of the subscriber level. The BG's configured (default) DLS server is used for all
the subscribers that belong to this BG. It is also possible to provision a BG without an associated DLS server, but of course this will disable Integerated Device Management.
At the system level, it is possible to define a Default DLS Server

will be proposed (preselected in the GUI) as the associated DLS server for Business Groups created via Assistant and
will be used as the associated DLS server when a new Business Group is retrieved by Assistant during Synchronization.
Data Consistency: Lotus Sametime Unified Telephony -- DLS Devices
During subscriber/device management at the Lotus Sametime Unified Telephony Assistant, system-wide
as well as subscriber specific
Lotus Sametime Unified Telephony data are passed to the DLS in order to create/update the related devices. To minimize the load on the DLS, the Assistant monitors whether changes on the relevant attributes were made and updates devices only when needed.

Provisioning of certain device attributes also requires modifying the related subscriber. If performed from the integrated device management, the subscriber configuration is semlessly updated at the time the features are activated on the device.
DLS Device Management Integration: GUI
The DLS Device Management is integrated in Lotus Sametime Unified Telephony Assistant's subscriber management. On its graphical user interface it permits the display, creation and essential configuration of multiple virtual devices per subscriber.
