  • Page 38 Direct Dial Inward trunk card Page 35 of 44 Dialling The central office sends address information in the form of loop disconnect signalling or dual tone multifrequency (DTMF) digits. Loop disconnect signalling Loop disconnect pulses are detected at speeds of up to 22 pulses per second. The minimum interdigit pause is 230 milliseconds.
  • Page 39 Page 36 of 44 Direct Dial Inward trunk card When the DDI unit detects the high impedance loop, it sends a change of state message to the CPU. The CPU sends a release acknowledgement message back to the DDI unit, which will respond by returning to the idle state. Near End Release When the Option 11 disconnects the call, the CPU sends a message to the DDI unit, which in turn will respond by returning to the idle state.

  • Page 41 Page 39 of 44 Flexible analog line circuit card Functional description The NT5K02LB Flexible analog line card with message waiting provides an interface for up to 16 analog (500/2500-type) telephones lines. It can be installed in slots 1-9 in the main cabinet and in any slot in the expansion cabinet.
  • Page 42 Page 40 of 44 Flexible analog line circuit card Connections The Flexible Analog line card has 16 units. Each unit connects to the shelf backplane through an 80-pin connector. The backplane is cabled to the input/output (I/O) panel which is then cabled to the cross-connect terminal. At the cross-connect terminal, each unit connects to external apparatus by tip and ring leads.
  • Page 43 Flexible analog line circuit card Page 41 of 44 Note 1: Analog circuitry is powered with +/- 12V generated from +/- 15V. The maximum current imbalance between the +/- 15V rails is 100 ma per circuit pack. Note 2: 8.5V is regulated to give 5V. Note 3: This figure reflects 10 ma for ringing one telephone per unit.
  • Page 44 Page 42 of 44 Flexible analog line circuit card Ringers Ringing is supplied to the telephones at a frequency of 25 Hz with a voltage of 80 Vrms. The peak voltage is no higher than 125V. The Flexible Analog Line Card supports any number of ringers up to a maximum ac impedance presented to the line of 350 ohms.
  • Page 45 Flexible analog line circuit card Page 43 of 44 Ground button detection The ground button detector sends a recall signal 30 to 50 ms after the application of a ground on either the Tip or Ring of the line. The ground must be applied for a time greater than the minimum hookflash time.
