SLICOFI-2x uses either an IOM-2 or a PCM digital interface. In receive direction,
SLICOFI-2x converts PCM data from the network and outputs a differential analog signal
(ACP and ACN) to the SLIC that amplifies the signal and applies it to the subscriber line.
In transmit direction, the transversal (IT) and longitudinal (IL) currents on the line are
sensed by the SLIC and fed to the SLICOFI-2x. A capacitor separates the transversal
line current into DC (IT) and AC (ITAC) components. Because ITAC is the sensed
transversal (also called metallic) current on the line, it includes both the receive and
transmit components. SLICOFI-2x separates the receive and transmit components
digitally, via a transhybrid circuit.
between the SLICs and SLICOFI-2x:
