The LT link management layer controls and configures the Link State Machine and
establishes the target link requested by the user. It also controls the Link State Machines
at both the NT and LT throughout this process. The Link State Machine at the NT acts
as a slave and is controlled through the VOC channel.
The NT link management layer sets basic configuration capabilities of the Link State
Machine. Dynamic control tasks are not needed at the NT, because the NT acts as a
slave during link establishment.
The NT link management layer also holds transmission profiles used by the Link State
Machine. Transmission profiles are sets of predefined link profiles. Each profile consists
of a profile name and link parameters (for example, carrier frequencies, constellations
and symbol rates). Transmission profiles simplify the programming of the STPs, because
the LT only needs to name the profile instead of specifying a complete set of link
parameters. Transmission profiles are kept in the EEPROM and can be changed by the
user. The data structure of the transmission profiles in the EEPROM is described in
“EEPROM” on Page
