In this sample initialization the ELIC is set up to handle a digital IOM-2 subscriber. The
interfaces of the ELIC are shown below:

port 0, time slot 1. The subscriber’s HDLC-data is exchanged via the D-channel with the
SACCO-A. Monitor and C/I-channels are to be handled via the ELIC.
The SACCO-B communicates via a dedicated signaling highway with a non-PBC group
controller. A 4-MHz clock is input as PDC and HDCB.
Port 1 of the ELIC is to be used as active low output. Thus the port should be linked to
pull-up resistors.
