Structure:

I032/050 - Composed Track Number

Definition: Identification of a system track.

Structure:

Extended item.

I032/050/SUI - System Unit Identification

I032/050/STN - System Track Number

(FX)

Notes:

  1. Each Track Number (i.e. either a Master or a Slave Track Number) is composed of a System Unit Identification (i.e. the identification of the SDPS unit processing the) together with the relevant System Track Number (i.e. the number of the track local to the SDPS Unit in question).
  2. The Composed Track Number is used by co-operating SDPS units to uniquely identify a track. It consists of the unit identifier and system track number for each unit involved in the co-operation. The first unit identification identifies the unit that is responsible for the track amalgamation.
  3. The Master Track Number and the possible extensions (Slave Tracks Numbers) are identically composed.
