4.4.1 CHB308 (3 CO Line and 8 Hybrid Interface Board)
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.
