3.3.3 CBIB (CID Loop Start CO line + Basic Rate Interface Board)

Description

The CBIB can be installed on the LCOB/STIB/CBIB connector, and provides 2 CO/PBX Loop Start CO Line interfaces that support pulse/DTMF signal and ISDN BRI T-mode interface. CO Interface contains ring and loop current detection circuits, A/D and D/A conversions, and pulse signaling circuit.

The CO port of the CBIB can be optionally equipped with add-on boards (Figure 3.3.3): CPCU2 (FSK CID, Polarity Reversal & Call Progress Tone detection Unit 2) to detect FSK signal for the incoming Caller-ID, polarity reversal and call progress tone; PRCPTU2 (Polarity Reversal & Call Progress Tone detection Unit 2) to monitor polarity reversal and call progress tone; or PRU2 (Polarity Reversal detection Unit 2) to monitor polarity reversal.
