TN780
The TN780 connects to and monitors an optional external Stratum 3 clock for digital frame timing. It also couples the clock output to local clocks. The TN780 supplies master timing to the system and produces the following tones: call progress, touch tones, answer-back, and trunk transmission test. It has 2 MHz, 160 kHz, and 8 kHz clocks. This circuit pack can transmit the system clock and tones on either TDM bus A, TDM bus B, or both.
The TN780 is administrable to produce 5 tone plans (for countries outside the United States) other than the United States tone plan. Six tones can be customized in each plan. The TN780 supports µ-Law or A-Law companding.
