1.6.2
The ELIC is an optimal solution for key systems like a PBX. When selecting the
multiplexed D-channel architecture, the ELIC covers switching, layer-1 and layer-2
control for the entire system. Together with the IOM-2 compatible Siemens transceiver
circuits, a complete key system can be build with a few devices.
