STMicroelectronics L3092
the L3000S line interface circuit and the L3092 control unit. The kit implements the main features of the BORSHT functions: - Battery feed (balance mode) - Ringing Injection - Signalling Detection December 1997 - Hybrid Function The SLIC KIT injects the ringing signal in balanced mode and requires a positive supply voltage of typically + 72V to be available on the subscriber card. The L3000S/L3092 kit generates the ringing signal internally, avoiding the requirement for expensive external circuitry.| Part No. | L3092 |
