Data Sheet
2.3
The layer-1 functions for the S/T interface of the SCOUT are:
– line transceiver functions for the S/T interface according to the electrical specifications
– conversion of the frame structure between IOM and S/T interface
– conversion from/to binary to/from pseudo-ternary code
– level detection
– receive timing recovery
– IOM timing synchronous to the S/T interface
– D-channel access as specified in ITU I.430 (see chapter 2.2.7.2)
– activation/deactivation procedures, triggered by primitives received over the IOM C/I
– execution of test loops.
