Line Interface Cards
Line interface cards (LIC) provide a computer-controlled interface to the PBX extensions. The
different types of line cards used in the Octel Overture 200/300 configuration are as follows:
- LIC4
- LIC8
- DLC16
- ILC12
Each 4-, 8-, 12 or 16-port line card connects to PBX extensions through a 25-pair cable. The 4-port
and 8-port LICs are based on the original D.I.A.L. software technology. The DLC16 and ILC12 cards
are based on the digital signal processing (DSP) technology to interface with analog ports.
The LIC4, LIC8, and DLC16 are FCC part 68 registered. The LIC4, LIC8, DLC16, and ILC12 are
BABT-approved for use in the United Kingdom.
