PRELIMINARY
3.3.1
The S/T interface uses two pairs of copper wires (dedicated to transmit and receive) for
2B+D data transfer. It builds a direct link between the VIP and connected subscriber
terminals or the Central Office. It supports point-to-point or point-to-multipoint modes.
Data and maintenance information is accessible by DELIC via the IOM-2000 interface.
