DLS is the central component with which devices, QoS parameters and the software distribution of IP devices are administered. Integrating DLS in a network makes it possible to take stock of and manage the IP device infrastructure. After participating in the course the service engineer will be able to carry out a DLS initial installation. The course covers the operation and general functions of the DLS by means of service examples and practical exercises. Any expansions with additional end-user devices (initial installation), as well as the relocation of telephones, will also be covered.
