In this sample initialization the ELIC is set up to handle a digital IOM-2 subscriber. The
interfaces of the DOC/ELIC are shown below:
Figure 3-9
The subscriber uses the ELIC’s CFI-port 0, channel 0 (time-slots 0-3). The subscriber’s

PCM-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.
