Features

Tone transmitter

The TDS/DTR tone transmitter provides 30 channels of tone transmission. Up to 256 tones are available as u-Law or A-Law and up to 256 bursts and cadences are downloaded from the CPU.

The TDS/DTR card does not provide the Music on Hold feature as do other TDS cards. The music source must come from a standard trunk card.

Tone detector

The TDS/DTR card provides eight channels of DTMF (Dual Tone

Multi-Frequency) detection in A-Law or µ-Law.

In North America, pre-programmed data is configured for µ-Law tone detection.

SDI function

The TDS/DTR card provides two SDI (Serial Data Interface) ports.

Refer to “SDI ports” in Installation planning (553-3001-120) for more information.
