The layer-1 functions for the S/T interface of the IPAC-X are:
– Line transceiver functions for the S/T interface according to the electrical
– 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-topoint, 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 IPAC-X can be used, are
