The CHB308 can be installed on the CHB308/CSB316/SLIB8 (CN2) connector of the MBU or EMBU, and provides 3 CO/PBX Loop Start CO Line interfaces that support Pulse/DTMF signaling. Each interface contains ring and loop current circuits, A/D and D/A conversions, and pulse signaling circuitry.
It also provides 8 Hybrid (8 DKTs or 8 SLT interfaces) ports, and can detect FSK signal for incoming Caller ID, DTMF signal for incoming caller ID, call progress tone.
It also provides three on-hook connection paths for CID/SMS.
