TN2182B Tone Clock
The TN2182B integrates the tone generator, tone detection, system clock, and synchronization functions onto one circuit pack for use in standard, high, and critical reliability systems.
- Supports 8 ports for tone detection and allows gain or loss to be applied to Pulse Code Modulated (PCM) signals received form the bus
- Provides Stratum 4 enhanced clock accuracy
- Supports MFC signaling and places single tone on any of the 256 time slots of the system's Time Division Multiplexing (TDM) bus
- Provides continuous, cadenced, and mixed tones
- Allows administratable setting of tone frequency and level
- Detects 2025 Hz, 2100 Hz, 2225 Hz modem answerback tones, and provides normal and wide broadband dial tone detection
