Ericsson LG - LCOB8 8 ports Line CO Interface Board

The iPECS-MG LCOB (Loop Start CO Interface Board) is a board for PSTN interface on iPECS-MG system. There are three kinds of LCOB. The LCOB4 is for 4 ports PSTN Interface. The LCOB8 is for 8 ports PSTN Interface. The LCOB12 is for 12 ports PSTN Interface. The LCOB basically supports Caller Identification (CID) detection, Polarity Reversal (PR) detection, Call Progress Tone (CPT) detection. But the optional CMU4 board is needed in case of call metering service (50Hz, 12kHz, and 16kHz). And, the LCOB has one Power Failure Transfer (PFT) circuit for 1st port.
