The layer-1 functions for the S/T interface of the ISAC-SX are:
– line transceiver functions for the S/T interface according to the electrical specifications
– conversion of the frame structure between IOM-2 and S/T interface;
– conversion from/to binary to/from pseudo-ternary code;
– level detection
– receive timing recovery for point-to-point, passive bus and extended passive bus
– S/T timing generation using IOM-2 timing synchronous to system, or vice versa;
– D-channel access control and priority handling;
– D-channel echo bit generation by handling of the global echo bit;
– activation/deactivation procedures, triggered by primitives received over the IOM-2
– execution of test loops.
The wiring configurations in user premises, in which the ISAC-SX can be used, are
