This TS specifies the standards allowed to implement Layer 1 on the Iu interface. The specification of transmission delay requirements and OAM requirements are not in the scope of this TS.

The main functions of Layer 1 are summarised in the following:
  • Interface to physical medium;
  • [ATM-Cell delineation];
  • Line clock extraction capability;
  • Layer 1 alarms extraction and generation;
  • In-sequence delivery;
  • Transmission quality control.
