Texas Instruments TCM129C13
The TCM129C13, TCM129C14, TCM129C16, TCM129C17, TCM29C13, TCM29C14, TCM29C16, and TCM29C17 provide the band-pass filtering of the analog signals prior to encoding and after decoding. These combination devices perform the encoding and decoding of voice and call progress tones as well as the signaling and supervision information. The TCM29C13, TCM29C14, TCM29C16, and TCM29C17 are characterized for operation from 0°C to 70°C.| Part No. | TCM129C13 |

They provide all the functions required to interface a full-duplex (4-wire) voice telephone circuit with a TDM (time-division-multiplexed) system, and are intended to replace the TCM2910A in tandem with the TCM2912C. Primary applications include:● Line interface for digital transmission and switching of T1 carrier, PABX, and central office telephone systems
● Subscriber line concentrators
● Digital-encryption systems
● Digital voice-band data-storage systems
● Digital...
